Worldwide Audio Wednesday





The Portable Audio Fest is coming (Japan)





Girls holding audio stuff they don’t know the name of…or care but nobody looking at them cares that they don’t care so who cares.


(insert favorite company name) +Black friday


90% chance you will spot a deal O’ the year going on



e-earphone is selling stuff at a reasonable price and calling it a sale I think?

Some legit deals to be found though






Wordwide Audio Wednesday





World Wide Wednesday Vol1                 11/22/2017




FiiO is about to release the new F9 Pro Hybrid IEM with Knowles BA tech

They are also organizing a tour on Head-Fi and application to join can be found here

(I will be in the mix so a look will be found right here.)




Shanling is also hosting it’s first tour in North America and it is sending 3 DAP’s at once to the reviewers chosen. information on that tour can be found here.


(They follow me on Twitter but do not reply to me …about anything, anywhere, ever.LOL, whateverz, it is news!)





Hiby has begun the process of delivering the first Hiby R6 DAP units outside of China/Asia and reviews and impressions should start coming in on that soon.

(I will be in the mix so a look will be found right here.)

Info on the device below




The long awaited FiiO Q5 amp/dac is slated for a December release for $349.99

(I hope…who knows?)





Will edit and expand sources to include the gobs of stuff I come across. Somebody once laughed at Headphonia in a PM about their daily events. No, it’s smart. the traffic flows have patters and in between reviews you let the tide go too low or you use what they call “B-roll”. 20 year old tactics that work still. Gonna do Photobomb Friday’s if you folks tempt me!!










Unique Melody ME.1 Planar IEM REVIEW

**Waits for Unicorn IEM**
Unique Melody: Hold my Beer, I got this..

Like a Game of thrones, The Sony EX1000 has finally been put down

by the Unique Melody Me.1

Unique Melody ME.1

The Unique Melody Me.1 is what is known as a “Planar” IEM

It is a technology developed and used for expensive headphones costing in the thousands of dollars. Recently the technology, forms of it, have been miniaturized and used in IEM or “In Ear Monitors”.  This is a very good thing for music listeners obsessed with detail. The minutia that is barely audible and sometimes lost to harmonic distortion is now available to you, the O.C.D crowd (me) and people who expect the whole recording to be played back…ALL of it



Sound impressions

Unique Melody ME1 FiiO X7MKII

Finest, clearest most impressive sonic playback of any IEM I have ever heard at any price.

The black quiet background is unlike any BA,Hybrid or Dynamic driver I have ever tried. It is absolutely addicting.

A Benchmark.

The sound of the needle gliding along between tracks on a vinyl rip is like being there. Next to Mom’s record player again, young, loving music and not analyzing it.

The moments between “The Battle of Evermore” and “Stairway to Heaven”


Those kind of moments are why I love this hobby.

I decided before starting to write this to just say what i think without trying to be some balanced robot infonator passing facts and general thoughts on to you. Nah, fuck that, these fucking RULE!



It is very much like the Sony EX1000. No measured increase of note between 20Hz and 1Khz. It is very clear and the speed of planar is second to…nothing. Bass guitar is outstanding. The pluck and pull and resonance of bass strings on some thing like the Violent Femmes “Blister in the Sun” is pure joy.


Who is she? No idea? Mommy or Daddy sure know their freakin’ music though. Whole album sounds sick on the Unique Melody Me.1


The best pairing for this IEM is the FiiO Q1MkII with it’s hardware bass boost switch. Most any good amp with a good bass switch will bring out the thump in these in a way an EQ cannot. Most DD or BA can be EQ’d to a reasonable point but for thump these love a good hardware my ears anyway.



Stevie Nicks and Lindsey Buckingham are an awesome pair of Male and Female vocals. Christine Mcvie reaches a little higher and brings in what is the sole weakness of the Planar…all of them. From 1.5Khz to approx 4.5Khz there is a harmonic event. A dip. Just prior is often a hump. Vocals on planar IEM without EQ can come off as shouty or odd if no EQ work is done.


Bass can go up because…it’s planar,

mids will not become veiled.

1Khz is very sensitive with this IEM IMO and it is my dip.

I do that at 400-500Hz usually but here it is 1Khz then I slow rise peak between 4-6Khz

Pretty simple and the payoff is perfect mids that transition to treble well, anchored by tight and authorative bass if you want it to be



“Telephone Line”

Woooo!! WOOOOO!!!

every crispy little detail pulled out and layed there for you. NOTHING shaded, trimmed,dulled…nothing. I coulda used any track with some sparkle but I was listening to this, wanted to try the widget so BAM….there ya go.

Science,  muf __kers!!


Product Specifications

Impedance: 23.1 Ω
Diaphragm Diameter: 18.5 mm
Magnet Type: Dual-Layer High Strength Neodymium

Shell: 3D Printed Medical Grade Acrylic with CNC Finish Connector Type: 2-Pin Protruding Connector
Cable: 6N Single Crystal Copper
Cable Termination: 3.5 mm Headphone Jack

You can change the cable..

But why??



Pimp C would blush….then wear it.

The cable is sick, the comfort is great (I use comply) the earhooks are soft and easy to adjust to your ear and the cable is sick….did I mention that?



Un rivaled SQ

Speed of driver and it’s assurance of the TOTL quality

Very responsive to EQ

Comfortable for long listening

The cable is unicorn hair dipped in gold


EQ near 1.5-4.5 Khz would be advised

hardware bass boost really needed to push bass properly


Your desk without these on them

I once watched Twister6 stumble over announcing one top of the line IEM after the other till he said he would stop making such grand statements and I thought..pffft, get a grip dude!

Now I am looking at my EX1000 considered by many old timers and myself to be the apex of dynamic in ear monitors. And I find myself rationalizing that they are in the Dynamic driver world but I am just splitting hairs over here. The Unique Melody Me.1 are the finest IEM on the market and they are not over $1000, they are not even near Unique Melody’s most expensive IEM yet here I am calling them the King.


Do I rec em?

They are in the header image of this site.

FiiO X7Mk II Hi-Res Music player REVIEW

Fiio X7mkII

Original FiiO adverts for player

  • Balanced

  • + DSD + BT 4.1 aptX + Dual mSD + Dual Band WiFi + Optical



Shii, let’s get right to the point

There has been a lot of discussion about the sound of music players and due to laziness or stupidity or both, the terms often used to describe speakers , headphones or any audio transducers has been ascribed to Music players as well and let me tell you it is total bullshit.

There is no loose bass, recessed mids or rolled off treble with a music player which has at it’s heart a DAC which is a Digital to Analogue converter.

It converts digital data into analogue data.

That’s what it does.


There is a thing happening. Cannot measure it. Cannot do anything but marvel at how some music players using the same exact DAC cam exhibit a tonality that is so different from another.

ESS9018K2M  Used by OPUS #2 (x2) and Calyx-M (x1)

They sound nothing alike and it has nothing to do with dual DAC’s.

The X7MkII is using an ESS9028Pro (x1) and the Dx200 (x2)

They sound different. I prefer the single DAC implementation but can appreciate now (unlike a few months ago) that it is a fine device in it’s own right. NOT my type of sound but very well liked by some.

Excluding all the babble about “loose” and “recessed” lets put them on one plane and call it a neutrality line

Warm (implies some sort of perceived focus in bass and vocal range)



FiiO X5iii

Shozy Alien +

Neutral ( no emphasis perceived anywhere along frequency)

FiiO X7 *1st gen stock amp*

DX200 *stock amp*


Cold (implies some sort of perceived focus in treble, perhaps forward mids)


Aune m1S

If that is reasonable, and I think it is, I would place the FiiO X7mkII in the Neutral category with a slight lean towards treble. It seems to have no more weight to bass than the 1st X7 but the clarity seems…well…clearer. The minutia in some music is there and while DAP’s that are leaning north of neutral can be a bad match for long term listening the X7mkII is actually the opposite. It is more engaging and comfortable than the X5iii and warm music players are supposed to be good for longer term listening.

Maybe true? But the X7mkII is an exception to the rule which makes it…exceptional.



I was unable to get past the tiny font on the Cayin i5.

Sometimes a simple little thing can make a device almost un useful if it does not mimic an ipod like ease of use experience with as few clicks and swipes as possible and a minimum of missed touches/clicks.

The FiiO X7mkII is a mature, easy to navigate Android based music player with no annoying habits. I have had it for 5 months and picking it up and using it is a thing done without thought of any kind.

I do not have to “put up with” anything annoying.

There are 3 basic themes.

Several ways to browse your music

The ESS9028PRO has 7 filter settings embedded in the DAC to make subtle adjustments to the sound

Screenshots taken with players screen capture

(hold down power and “up” on rocker switch at the same time for 1 second to do this)

 Using the thing

Adding your music is as simple as plugging it into a PC or MAC and dragging the music files onto the devices storage. It is in fact less tedious than using itunes with an idevice.

Most common question I hear from folks not crippled by music gear collecting is:

“How do I add my damn music??”

Just plug it in bro.

It will ask to be storage device and you allow it then find it on your computer where your other drives are and open it and go.

Easy peasy.

Photo Bombing





fiio x7 and sonyma900Fiiox764audiou12

 Compared with other music players?

This is a thing you can ask directly in a question as I believe the headphones/IEM have the final say in the sound so I would need to know what music and what other gear. I can do it. Have no problem declaring one over another but just in general terms? Nah, that’s a hype game parlor trick.

X7ii and OPUS2fiio x7ii and x5iii

What do I listen to?

DSD when I can

Vinyl rips of classic albums

70’s Rock, Hip Hop, Reggae

I sometimes EQ Bass up for a more “live” feeling and i do it with every device that I can

The good

Sound Quality is pretty damn awesome

Very easy to use

You can change the amp at the bottom of the device and get more power without stacking

Battery life will get me through a regular day with no worries

Android allows you to use other music apps like on your phone and Neutron will work with this and not resample to 48Khz

The bad

The EQ is just O.K.

1/2 of screen is taken by control panel and other half for album art? It would be nice to auto hide that big panel

The leatherette case is very very hard to take off. Almost had a meltdown taking that back off

The Ugly


It sounds great, it is priced great compared to it’s rivals, the company updates the device to add things that people ask for.

This device was given to me for free.

Does that help make my review positive?

Legit question.

I dunno? I had it for months, I use other music players too. I enjoy being brutal and honest and sometimes burn bridges because of that.  So I guess no. I definitely like it and have no problems telling you it is one of the finest devices you can buy to listen to music with and it will not cost you a shit ton of gold. Your good, this is a good purchase.

Highly rec’d




I wanted to try a 2 pin for the Audeze since it is kinda ghetto stock IMO.

I contacted him and he sent me the BT version after some back and forth.

I like the Blue Benz

You wanna try the white one?

Um actually.


I admired the car salesman like vibe.

And hell, BT buds suck pretty much so picking my own 2 pin set and making them BT is pretty damn convenient. I got em for free so my White Benz feels pretty damn fine.

Does free make a difference in a positive review?

Probably does on some level but I got complaints so not enough to prevent sharing that so no….

Comes in a nice box.
Who cares?

Box people care…that’s who!!


  • Bluetooth 4.2
  • Smart-assistant support
  • aptX Codec
  •  Microphone
  • Media-control


I thought the red would indicate (right) but it actually goes only on left of isine20

Red is left on all IEM tried and the notch on the rubber surrounding the termination might be better if it has no bend. Easier to wear down or make earhooks or he could on request though cable is short so there is limited cable to work with.

Everything was worn upside down or backwards so maybe this set was a mistake?

If I turn the logos facing inside they fit a bit better on the 64 Audio U12 but not great. i gotta think this is an odd set.

Red is left and logo turned in makes them fit better on some sets.

Shozy hibiki


From PlusSound,

The red is right side with screws required to face outward, as provided in the instruction card. The only exception is with Audeze units which has the groove reversed, but red is still on the right. When customer specifies Audeze, we know not to include the cable bend. Otherwise, it would have it to make it more comfortable.

Pairing with all DAP’s with Bluetooth was very simple.

Keep holding button down until red and blue blink rapid and look for it on the DAP and pair.

Had no issues with any device



My man cave has Hawaiian beach towels on the ceiling


Stay gangster.



Take whatever the fu you like with you and suffer no audible loss in quality.


Unit housing kinda big .If i wear the cable behind my head like some Sony sets it fits better on the U12 and Hibiki but then I have to reach behind my head to touch the controller which is right behind my ear


If you have a set where the plug is on top and not bottom this is something to consider

Thanks to the guy who sold me the white instead of Blue Benz.

It was free

Sennheiser HD 630VB REVIEW



After all the self anointed “Audiophiles” turned their nose to this set of headphones lets step over the charred remains of their dimwitted, uninformed  and baseless words and take another look at was is actually….a REALLY nice set of cans 🙂











Some specs

  • Wearing Style: Headband
  • Ear coupling: Circumaural
  • Transducer principle: Dynamic, closed
  • Frequency Response: 10-42,000 Hz
  • Impedance: 23Ω
  • Sound Pressure Level: 114dB (1 kHz / 1Vrm)
  • Total harmonic distortion: <0.08% (1kHz, 100dB)
  • Bass Boost: +/- 5dB at 50 Hz
  • Contact pressure: 5.5 ~ 6.8N
  • Weight (headphones excluding cable): 400g
  • Accessories include carry bag and 3.5mm to 6.3mm adapter.


  1. Photobombing in 3…2…1







Wearing Style: Headband

  1. While the weight is weighty…the headband is comfy enough to make this a non issue. Not sure if these are as portable as advertised but that is up to the user.

Ear coupling: Circumaural

  1. Fancy way of saying this set is an over the ear design. It could be considered such unless you have very large ears. The pads are removeable/changeable

Transducer principle: Dynamic, closed

  1. Driver sizes are generally not released by Senn but taking off the pads reveals a 40-45mm driver

Frequency Response: 10-42,000 Hz

  1. There are no noticeable dips or roll offs between 20hz and 16Khz. I am sure of my own ears in that range and nothing jumps out as being off or spiked or recessed.

Impedance: 23Ω

  1. As these were designed for use with Apple or Android devices they are relatively easy to drive and most DAP’s will be fine. You can also use this off a smartphone though dynamics may suffer a bit due to lack of driving power

Sound Pressure Level: 114dB (1 kHz / 1Vrm)

  1. These get loud. As noted above, playing these from a smartphone is fine. Quality of the sound is another thing.

Total harmonic distortion: <0.08% (1kHz, 100dB)

  1. Mmmm, not much to say besides they sound very detail rich and with the bass adjustment turned off


  1. Bass Boost: +/- 5dB at 50 Hz


This is the point where fans of the brand turned their back. Not at the ridiculous giant headphone character commercial pouring salt into an urbanite cup to show bass response…perhaps one of the worst ad vids ever. THAT did not raise the ire of Senn fans….it was the bass dial on a HD series set. Essentially it was a rebuke by folks who had an image they helped create and foster and then were apparently duty bound in defending it. Head-Fi psuedo audophilia at it’s worst.

Contact pressure: 5.5 ~ 6.8N

  1. This is…pressure on head? I had not thought about it? Ultrasone often makes me think about that and head vices and torture devices from the 12th and 13th century but this set seemed to fit nice.

Weight (headphones excluding cable): 400g

  1. As mentioned earlier, I find the weight to be an issue less than the size which makes outdoor use a tough sell for image purposes. The profile is large and lots of folks may balk at that. Weigh?….meh, not that big O’ deal!

Accessories include carry bag and 3.5mm to 6.3mm adapter.

  1. The carry case is stout and nice and that with an adapter is all you get. The non removable cable was the 2nd biggest complaint and THAT is valid and listening or holding it does not need to occur before jumping on that. @PETEREK has told me that making a removable cable is no big deal.

The inline control and flexibility with 2 operating platforms may be related? No idea but this is a legit complaint. The bass dial bashers were just homers homering on and on but the cable is an easy and legit target.

It can be changed though!

Head-Fi User @PETEREK formerly known as CasperTFG is a well known customizer that has said he can do removable cable mods for this set


The reality it seems is that that the bass dial is quite polite and is no more impact full than the MEZE 99 Neo.

That well regarded set (by some, most) is in stock form about the same as this Senn set with the bass dial 1/2 turned or ¾.


With the dial fully turned off it is so polite it sounds small. The driver size would be suspected by anyone who likes bass dominant sets.

Actually the acoustic tuning done by Senn is impressive because it can go from polite to robust with a vent adjustment and still keep everything beyond 2Khz stable and clear. There is no compensation EQ needed to get back the sparkle. It never leaves.

While the 99 neo sounds intimate with a comfortable if not slightly smallish stage the Senn manages to display a bigger presentation with all forms of music from 70’s rock to hip hop.



Foreplay/It’s Been such a long Time

The studio created but seemingly live played
Foreplay/It’s Been such a long Time sounds big and spacey. The notes in the high treble come in clear and the sense of electronic drops of water falling off of a cliff into space all around sounds fantastic. The sense of space around your head is a good real music take on Dr Chesky’s panning test tracks.
This track sometimes/often sounds compacted in IEM and over ears but the 630 has just enough high end and good design to make this feel right.

Noted that these cans benefit from adjusting on head more than most due to driver position and baffle board design.

Outta 10?……Mmmm 7?



Wanna be Startin’ Somethin’

The first track on the classic album is held down by a prominently placed and talented 4 string bass guitar. It is of a quality hard to match when judging bass on a real music album. It took me years to get past mike’s issues and re-appreciate his and on this LP’s producers skillz.

synesthesia is a term used to describe people who see sounds as colors.
I happen to be one. It gets freaky responses so I keep it to myself. Was pleased to read the following when learning about Thriller.

“I have synaesthesia, and Quincy does too,” confirms Swedien. “The low frequencies are represented by dark colours like black and purple, while high frequencies are bright colours such as silver and gold. When I listen to a mix I want to see all those colours.

“I’m not a big fan of compression or limiting at all — I can’t emphasise that enough. On many of the recordings that you hear today, all the excitement and all the colour is gone because they’re so over compressed. I never did that. I would never have a compressor or limiter on the [master] bus, for instance. I want all that transient information there.

-Bruce Swedien

The Purple and Gold is a masterwork on this track and turning the 630 dial to about ¾ puts the darker colors near the front but never taking over the silvers and golds of the track.

Outta 10?……Mmmm 9?



While I usually use “On the Run” to check for staging in this instance I chose to focus on the woman announcing the departure of a flight to Rome. My recent experience with planar IEM showed how clear this can be and checking that on these returned a nice replay. No sense of veil or distance in the fundamental or harmonic region of the woman’s voice

Outta 10?……Mmmm 7?


Yep, trebs with 2pac

Heaven Ain’t Hard 2 find

This track is just stuffed with sample deck goodies. Stuffed. The better the driver and treble tuning the more of the stuff you will hear. There are spinners, dew drops, and sounds like from a carnival just far enough in the background that if your driver cannot reach their you’ll never notice. No biggie usually but a definite bonus when it is there because the tuning took you there

Biggest surprise of the 3 fundamental ranges.

Outta 10?……Mmmm 8?

I would rec this set to anyone who likes an audiophileish sound with an ability to adjust the sub-bass and bass.

That’s a lot of folks.

JVC HASZ2000 (My 1st review eva)









You get what you see. Nothing extra.

CNT or “Carbon nano tube” diaphrams/drivers were developed by the Chinese (I studied this) and J.V.C was the first to mass produce it in their IEM “FX” Series.

Essentially a 55mm driver dedicated to low frequency . They actually called it a “Subwoofer” (a 30mm driver handles mids and highs)

Full tech explanation here>>>>>>HA-SZ2000   JVC

It’s a Double Bass reflex design using the “Kelton Method”


Does this scream audiophile to you so far? It screamed Basshead to me.

Kinda screams this…

Old school 6×9’s…….Oh nostalgia. Before dedicated subwoofers were the norm this is how they got low and highs  (Car audio hi-fi ladies and gents) together…they “stacked” em.
Cars allow the space and freedom to divide and conquer the signal drivers but headphones……not much room.
JVC gets a lot of points for their creativity. This SZ series died a quick death due to many reasons.

1 Maybe the greatest Low frequency response headphone ever mass marketed and produced…….never aimed at the market most likely to eat it up
2 Outside design looks Hi-Fi while the sound signature is not.
3.Limited release and lack of follow up adjustments.
4…sadly the guy that was the genius behind this may be working in SIberia as it was an epic FAIL.

I give this 5 stars because it’s bass is unmatched. The impact is superior to a line named Xtreme Xplode (Noooooooow they aimed at the crowd[​IMG])….with the 2nd best design.
It responds to eq adjusting unlike any headphone I have held. The response line is a rubber band that will do about anything.

The BASS…might make you sick. Previous owners might be able to comment on this. If you boost the already dominant bass it can cause a kind of nausea. I saw friends in my car audio days vomit after to long a ride with 2 15″ subs slamming into the cars frame.

If someone blows into a large bottle a moment of resonance occurs and you feel it. It’s uncomfortable. While your bass is pounding your head a subsonic tone is coming through those 2 tubes and though you cant hear it it is filling your ears and body. It might be in my mind but I don’t think so. These cans bass might make you feel ill[​IMG]







I will update this later.

This is an import series that is apparently discontinued. I would recommend any bassaholic chasing the next big hit to get these before they are no more or go up in price because a niche’ market of Bass oriented audiophiles take a shine to it and drive the price up.

Bass volume (exceeds amplification max of a FiiO e12) 1st time experience. That is by far ..nothing did that before and it has a 16 ohm impedance?
Bass Depth (rated down to 4Hz….the first time I never questioned a claim of production beyond the audible range because you can feel it)
Bass Texture (It will do whatever you want it to do from the low end side…it’s ‘texture” is so smooth it slips down your throat and makes you sick…that sensation anyway)

I will update this review after a while of usage. It has only played with Hip-Hop music.

Used for extension at high volume:


Used for Bass hit impact:


Used for Bass response (speed)

EDIT: 3/21/14

I ended up changing the pads on these.


This took 2 minutes and changed the mids and highs a lot. Not sure why JVC went with the smaller padding but it was a terrible oversight.
Bass impact was not altered by the pad change. These came off the 55x of JVC’s XX series so I didn’t expect bass impact would be diminished. It feels tighter.
These are the hardest bass cans I have ever heard. The Honeymoon fanboy period is over. These are just awesome.


Original Post from Extreme Basshead club on Head-Fi Below







  1.  This is not a review it’s an argument for calling this set of cans the hardest hitting on the consumer market. That claim needs data. Others need to be able to confirm and compare their cans.  Give me some time.
  2. Everything is based on changing the original pads to a firmer pleather


Making the case

Everything in the robust sub-bass region is related to a “Kelton Subwoofer”.



Exploded view
(The second panel from front shows the cover under the pads. It’s twisted to 2:30 instead of 6:00 where the bass ports come out
Who the **** does that? This is JVC in a visual. You go all out to make something special and **** 1 little thing up. That’s JVC in a nutshell. Every layer is tech awesome and you throw some shallow pads on the top…..tha fuu??)

Preview of visual aides

 Lvl 1 test

(Shows energy being transferred by driver to cage)

Not common but not rare. Any 50mm+ driver with low,mid,high end bass should be able to do this. Some 40mm possibly as well.
This test can be gamed and the paper size and material can greatly effect the visual display of energy.

Lvl 2 test

(Shows energy being transferred up through ear padding and air pressure change within area between driver and ear)

This is very un-common.  That paper is  analogues to human skin and the energy being felt by it. It’s not a perfect analogue but the point is made fairly well.
The final video will be an unedited one showing exact settings prior to display. As this it will be a Cowon at 34 volume with a flat 5 band eq mach3bass at 10 and BBE at 8. Fiio e12 amo with bass boost on, gain on and volume knob at approx 50% (all will be clearly seen in final video).

Anyone who has bought a pair of bass cans because they were told their “face will melt”, “eyeballs will shake” or any # of wild claims only to get the cans… put them on and be absolutely underwhelmed in the face melting, eye ball shaking dept……will appreciate the effort I put into SHOWING what it does v.s. saying what it does.
This display is not near distortion levels. I like my cans. I do not need to damage them for entertainment. The work they do under elevated but not insane levels is clear enough/beyond most if not all.

This section is reserved for a video of cans that display equal to or exceeding energy
transfer through the pads. Lower padding held down by opposing cup or object. 3 sides
left unimpeded. Using this track 3:40-4:02 to be exact. Anytime. PM me.




Test Tracks

Why this track?

Because it is like a Hip Hop producer channeled  Phil Spector’s “Wall of Sound”.
It is waves of layered bass hits underpinned with a sub-bass stroke that will keep the driver busy at all times.
This track shines on the sz in a way that puts other heavyweights to shame. It articulates and reproduces all of the mastered track with authority. If you listen and you think..”meh…just another hip hop track” you’re not listening loud enough or your cans just won’t bloom under the crushing pressures this track puts on the driver diaphragm.
100 million You-tube hits and I’ll bet a good portion are pure breed bassheads.

Why this track?

Because it is the classic bass hit. An atomic blast dressed up like a proper bass hit. It’s also nostalgia for me. This hit destroyed/exposed your favorite can.
If you do “A” “B” comparatives between cans while they’re together (only way it should be done) then this will make one stand out. The Yamaha 500 and Ultrasone 900 do this hit well because it is good at mid/upper bass showcasing but the sz still takes this slice of cake. What is a safe listening level? Is this too much? This track at high gain will make you ponder such deep questions.

Why this track?

Because it is a high gain track. It pulls mids and highs and ties them to the bass smoothly if bass is raised by +15dB. It is new. Well mastered and displays a punchy hit usually reserved for a slightly higher Hz but places it lower. (Maybe aimed at Car Audio heads) One of my newest fav’s

Why this track?

Because this is a track that seems to have 2 layers of low end bass response however it has 3 clearly. The 3rd is only heard at very high low end gain. It sounds like a different song on these cans. Without mentioning cans I’ll say my 2nd favorite start to echo while these rigid housed drivers keep it together. This is similar to the Wiz track in that you are always being hammered and sometimes with multiple magnificently mastered low end spikes. While the Wiz is pinned with a low tone this is hung with higher hits while low 20-35Hz punch you in between. It’s like an inverted Wiz track.


Science n’ stuff


This is where the 77’s end…along with the Pro 900 and ANY other 40mm driver and most 50+ with plastic housing. Just before both the 57mm JVC and the 40mm titanium Ultrasone physically distort they start a resonance/echo chamber acoustic downfall…and then immediately begin distorting

Sound waves are longitudinal waves (Red line is your driver)

The SZ is using chambers to force high freq sounds out by filtering them naturally since high frequency
waves reflect easier than low frequency waves.Low are longer and wider. They deemed the 55mm driver a “Sub-woofer”. It is essentially working in that fashion. Having a driver dedicated and forced to fight through chambers is assuring a powerful low frequency response since the driver is technically only being tasked with that duty. Mastering these headphones to get the two drivers to cooperate is the user end challenge. For Hip-Hop (to this user) these are perfect. They are the ultimate “Basshead” cans though most bassheads have never heard of them. They do not look the part and were not even marketed in that way.


For f__ks sake…Embrace the bass.

So they built a Sub-woofer based set to be played loud but it’s not for bass enjoyment????


O.K., Sure.

That’s why folks got 40mm single driver celebrity endorsed basscans on their heads which will crumble and distort long before the ones you guys spent ages to build because you couldn’t embrace the bass? How about…mmmm..I dunno….market them just a little to the tween-er crowd that uses moms money or what they saved at McDonald’s working part time to buy the baddest ass headphone bass monsters on the planet. Now you got folks rec’ing (insert ****ty can here) because they don’t even know what the **** you built. Accidental Einsteins …awesome[​IMG]


The thing…I was trying to tell/yell at folks for 2 months was what was the big deal. These really do shake your eyeballs. They vibrate the upper neck as well.
After having these for 3 months it’s clear to see,the way a bass can delivers the sensations beyond the pads is related to the human skull. The rear of the pad vibes but your skull…it’s thick. The area in front of the pads like your cheeks and the short jump to your orbital area and your meat filled neck……if you tune these right and have solid pads you are going to be very impressed. It is a unique experience

Below is the sz


Can shaking hit on Kendrick Lamar’s MAad City (above)

Massive bass bomb from Rah



**This was on a reduced gain because the SMS could not reproduce this hit without distorting/crackling unless I lowered the gain. That lowered gain is the same for the sz snapshot. It’s an apples to apples comparison.

I’ll revisit this hit later to see what the sz can do before it’s own limit is reached.

Deficiency Notes

Denon has an entire industry built around it’s cans and the improvement of them. Take a diamond…shine it up…I get it.

Many great headphones have deficiencies that are adapted to and overcome by loyal owners who see the profit in further investment. This is great…I wanna make it greater kinda thing.

The SZ2000 must have a pad change. End of discussion.
You wanna hear the mids and listen to Jazz? Get some Beyer pads/HM5’s
You wanna vibrate your neck? Get a pair of JVC 55XX grab the pads and toss the rest in a river and tell yourself it’s an offering to the bass gods and never look back.
Sometimes you gotta do ****. Suck it up and go the extra step.

Pre-conclusion conclusions


  1. The Carbon diaphragm is allowing for a stronger low frequency response. It has characteristics that caused JVC to use it for their “sub-woofer”.
  2. That brass
  3. Hardened ass end reflecting almost all energy forward via direction (bass tubes) or reflection (metal driver housing)





Ya missed the entire thread devoted to the cans.

While I wasn’t looking these cans became highly controversial..[​IMG]
Sub-bass cannons with vids on vids showing it not saying it…and it’s contro……….like I said “DEAR LOOOOORD”!!!

Great write up by a Non Hip hop head
