Campfire Audio’s CASCADE Headphone REVIEW

The crunching, grinding harmonic chaos that is an electric guitar with pedals down is just so ….damn…hard to get right. It does not matter the design or driver type, something is always missing. It’s not missing now




Time:          1977

Place:         Some kids room, somewhere in America

Reason:     Reason?      Mom….GET OUT OF MY ROOM!!


cascade and farrah

That kid is so stoked!



This guy is so stoked!

Campfire Audio CASCADE life




The kid?

unfurling the biggest selling pin-up poster girl in history…

and you can see her nipple….for an 11 year old boy that’s like big time stuff.



The Guy?

I think the guy in the 2nd picture and the kid in the 1st are actually… the.. same.. dude!













Same lines that Campfire Audio has become famous for but in “L” size. Absolutely beautiful down to the last detail. Everything is awesome.

Seriously…it is.




“The real cycle you’re working on is a cycle called yourself. The machine that appears to be “out there” and the person that appears to be “in here” are not two separate things. They grow toward Quality or fall away from Quality together.”
Robert M. Pirsig, Zen and the Art of Motorcycle Maintenance


  • Well respected guy as it relates to voicing and building IEM in the audio industry.
  • Dreams of doing some over ears headphones.
  • Takes lots of time to get the reality and the dream lined up.
  • Pic posted above would indicate said dream.. has met reality


Respected, smart, dreamer…nails it.


I want some of that.


You want me to paint a picture?




**Bob Ross voice**

There’s a happy little aluminum cup over there, yeah..

moving up,…what do we have….oh,

it’s a nice yolk connected by a strong pivot section, for you folks watching at home any old brush will do….lets just enjoy, that’s what it’s all about …yeah?

The padding seems really nice and hey…those plush pads , like clouds…happy clouds being warmed by Mr Sun…….those clouds come right off! Lets just use black, it’s a dark color but it is one of my favorite colors because I can make almost aaaaaany other color with a little help from Mr. Black.

Alright then, lets dip our brushes now…just a bit,



Excellent pics and from all angles are at the site where you will buy it:


I have to this point,



Farrah, Robert Pirsig and Bob Ross into this.


1977…the ….house!!!





Moving right the fuck along…..








Closed headphones always have and always will fall short of open backs when it comes to a sense of space around the listener.

That said, Pink Floyd’s On the Run which is fantastic for panning and spacial audio cues sounds great. Using mostly IEM lately and not my MA-900 has sort of conditioned my mind to getting a sense of space from tuning more than actual air coming into my ear in addition to the sound.


The left to right and back pans,  and  both sides panning to opposite sides simultaneously is well captured as is the woman’s gate and boarding announcement which resides partly in the early mids but is very clear which is not the case with over extending bass.






Tupac Amaru Shakur (beloved god of THUG LIFE)…his favorite song was:

“Vincent” by Don McLean

Just a knowledge bomb for ya.

About that bass…


I bought these because having a driver with good mids and great bass is something beryllium drivers are becoming famous for. That and it’s cups being made of a metal along with the reputation of Campfire Audio is mostly why I pulled the trigger.


On 2pac’s Ambitionz az a Ridah’ the bass thump is clean and falls fast. The speed of the driver is preventing an elevated bass from becoming a mid frequency issue. Nothing else is clouded or less resolving because of the bass hit that pins down the entire track. I like bass but I like mids even more. Scooped mids kill. They kill hopes, they kill smiles they ..

I would rather it sound as if the lead singer were standing on my fucking face than sound like he was in another room behind the band. This set makes me not have to deal with either discomfort but if they had thin mids or distant vocals I would be shredding them in a video..I NEVER DO WRITTEN REVIEWS OF GEAR UNLESS IT IS BOSS. Vids are easy. Writing is an A.D.H.D torture event.






AC/DC’s  Girls got Rhythm,

I have come to realize how much this track which is a fantastic vinyl rip, throws guitar and vocals a notch or more back whenever there is a dip in the mids. If the 300-2Khz range is warped it will show on tracks like this and Fleetwood Mac’s Gold Dust Woman loud and clear.

Noteworthy to say the least is the ability of this set to play back guitar with distortion pedals in a way, I have not heard on many sets of head gear of any type, be it B.A. , PLANAR , DD..IEM, on-ear or overear.

The Beryllium driver coating is clearly cleaning things up via speed and recovery of all the minutia that happens during distorted guitar playback. It is almost like a unicorn for folks who have never heard good audio gear as they have never heard it and literally have no idea what they are missing. Ignorance is not bliss but it helps to not drain the wallet like this hobby does.


The crunching, grinding harmonic chaos that is an electric guitar with pedals down is just so ….damn…hard…to get right. It does not matter the design or driver type, something is always missing. It’s not missing now



Hearing this vinyl rip like this and knowing I can grab this set anytime and hear this kind of replay is worth the price of admission alone.





E.L.O Telephone Line


All kinds of trebles ready to make you want to rip your skin of your face if the driver has spikes in the wrong areas.

Seriously…50Hz tone at 145dB for 20 minutes or

8.5Khz at 145dB for 5 minutes?

Man, I’d get to minute 2 of 8.5Khz and cry before going insane and jumping out a window and impaling myself on something.

The FiiO F9 original version is good for 2 songs in a row and that is it. Game over, fatigue has arrived and annoyance and anger are following close behind. I bought the Beyer T1 and long term listening sessions with that beauty was just impossible.

The Campfire Audio CASCADE is built for long listening. Maybe it’s the basshead in me but this is not a bassy set it is a mid centric one. This is built for full album sessions. I believe this is the first review I wrote while listening to the item reviewed the whole time.





1 = Get these things off my fucking head

10 = Sound so good I forgot something important and…don’t even give a shit. I’m in this hobby for the 10’s brah!


Well…I got an e-mail asking to change a boxing spar session to tomorrow instead of Sunday (J.S.T) and forgot to reply till typing that 1-10 stuff and he has a new baby and I am not gonna mail him at 11:50 P.M and wake his kid and piss off his wife.

My Review of the Campfire Audio CASCADE Headphones.  is done. A pretty good video review will soon follow.



A star and a movie from 1977.  EPIC,…like these headphones.


Adventures in HA-SZ2000 Pad Rolling



I’ve been using HM5 sheepskin non-angled pads for quite some time on my JVC HA-SZ2000, but I’ve been wanting to try some good angled pads. So I got my hands on a pair of MrSpeakers Alpha Pads, and some ZMF Calfskin Oval pads to compare to my HM5’s. I’m glad I did. The ZMF ovals went on easy enough, were pretty comfortable, and added some nice midrange and treble plus a bit of width to the sound stage. However, they took away a bit too much bass for my liking. Then I put on the Alpha Pads and the game was changed for me. The mids and highs were a drastic improvement, and the SZ had a wide and deep sound stage for the first time. But what made the pads the best choice for me is that no bass was lost at all, I still felt every hit. Plus, they are far and away the most comfortable pads I’ve ever put on the JVC. To sum it up, if you can get your hands on them, try the MrSpeakers Alpa Pads on your SZ2k/1k, you won’t be sorry.

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!!

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

LongitudinalWaves.gif <<<Your ear is here.
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




Above is an SMS DJ PRO which…

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
