Alright guys!!!! For all those who wanted measurements on the SZ2000's, goldenears.net delivered! I think this may have been due to an email I sent them about it... Anyways, here's the measurements on them! http://en.goldenears.net/index.php?mid=GR_Headphones&category=275&document_srl=49622

So I finally got an SPL meter, and am currently uploading the SPL measurement videos for the JVC HA-SZ2000 and the JVC HA-MR77X. The results aren't surprising (in a very good way).

 

In the meantime I'll try to catch up with all the posts I need to like and reply to!

 

AND Dischord that is really AWESOME way to crush my meager contribution lol!!!

Cool!!

That drop at 2k is what makes the non-eq folks cringe.

 

And everyone saying the bass needs amp..are right...very elevated mids.

 

Awesome work bro!!

wasn't entirely due to me. I suspect my email made them look at the sz2000 though. They're the ones who measured everything... Looks good. Veiled as hell though, but... Surprisingly it still is detailed? O.o and it is much more midrange focused than I thought it would be un-eq'd... A quick eq job would fix that right up most definitely. The measurements for it are all over the place. Thank the headphone gods for eq.

First impressions:

 

With no amp, these (obviously) are worthless. What everyone said here about using an amp is not a joke. Anyone considering purchasing these to use off of a standard PMP, forget about it. If you have sound card that claims to have a headphone amp, you will be disappointed with the sound. I have a ASUS Xonar sound card and the output is NOT enough to drive these.


XX Pads

I am using a Fiio E12 amplifier, bass boost turned on, gain swich on.

Xonar DAC: 10hz-30hz +7db 31hz-60hz +2db.

Vol Knob @ 1:30 (70ish%), for vision distortion 2:30 (75-85%) (This is really good for your hearing)


If you are looking for BASS, these are ******* BANGARANG. My ears give up before the SZ2000s begin to distort. Unbelievable. My girlfriend jumped in her chair when she first listened to these. I will quote her "Headphones shouldn't be able to do this!"

I played the track 'Massive Attack - Angel' and she went wide-eyed.

 

I read the hype, I saw the proof of bass but didn't know how intense it would be. HBB said the feeling these give you are a new sensation for headphones- he is absolutely right.

 

What I can tell you is this- at the level I listen to, my vision becomes blurry to the point to where the words I am typing begin to fuzz when the bass hits. I **** you not, I swear, that's how hard these hit. Another thing, if you hold your teeth close to each other they will chatter. There's a primal side of my brain that is actually frightened/alerted to the bass phenomenon these produce.  FINALLY, this is the bass I wanted and I got it. 

 

I listen to House, Minimal, TechHouse, Trip-Hop, Glitch-Hop, Breaks, and occasionally gangster rap. These bang on all of these genres, minimal especially. I close my eyes and let the sensations take over, it's surreal. I feel like I'm standing an inch from the speaker rack at the club when I listen to these.

 

I turned on Pink Floyd - Time for my step dad, these even blew his mind. I've owned/listened to the following cans for quite some time: RP-HTF600, ATH-M50, Sennheiser HD 25-1 ii, VModa M80, Denon D1100, RP-DH1200, AKG Q702s. None of them even come close to the amount of bass these can produce. When your eyeballs are having trouble reading the **** on your LCD screen, you know you've entered the end game that is the SZ2000s. As HBB said: Believe the hype. Haters gonna hate, but these are it. Look no further. 

 

HISTORIC.

 

I was laughing and at the same time wanting to cry as I read this. What a great day for Bassland.

SZ1000 sound signature = SZ2000 sound signature... Apparently really the only difference is the brass chamber on SZ2000 and the stuff they use on the SZ1000

That kinda jumped out at me too.  Good detail through the veil:blink:

O.K.

 

I return to now...to not looking at charts. (But I'm glad they are up!!!...cool:cool:)

there are cans that still retain detail through a thick veil lol. It jumped out at me too... But in a good way. Like, WOW! I get some of the detail even with the bass?? Score! Just remember that the tester for goldenears has heard 100+ headphones. Flagships and budget cans alike. I usually trust them. The scale they use is usually pretty accurate.

The SZs look obviously underdamped in those measurements. I tried looking for specs on the "Golden Ears Headphone Amplifier" but found nothing. The closest I could find is a certain "HeadRoom Balanced Desktop Amplifier" showing a 5.36Ohm output impedance, which is too high for the SZ's 15Ohm headphone impedance (output impedance should be less than 1/8 the headphone impedance). It also might be the case that JVC made up the 15Ohm headphone impedance rating.

 

As for amp use, the first time I got the SZ, I still didn't have the Fiio E12 and was using an E5. Compared to my 77X, the SZ was distorting near the same level as the 77X. I suspected that the E5 was distorting the signal, not the drivers, and confirmed this to be the case as with the E12 the SZ could go +15dB louder than the 77X.

SPL meter:

RadioShack Digital Sound Level Meter

 

mics_group3.gif

 

RealTraps measurements above show the device to be accurate around -3dB from 30Hz to 1KHz, C weighting.

 

 

Test track:

Isolated bass track of Wiz Khalifa - On My Level

 

I removed the vocals and other instruments in Wiz Khalifa - On My Level and isolated the bass track. So while the headphones may do better with specific sine waves, it may not reflect real-world reproduction. On My Level has become the community favorite for testing bass (hardest impact kick drum and teeth chattering subbass), so it was only apt to continue using it as _THE_ bass benchmark.

 

 

Procedure:

For the SZ I used the 77X earpads sealed with packaging tape. The 77X drivers are quite peculiar in that they require a high pressure seal to prevent distortion.

 

 

JVC HA-SZ2000 maximum bass SPL before distortion:

 

 

 

 

JVC HA-MR77X maximum bass SPL before distortion:

 

 

 

Results:

JVC HA-SZ2000 max SPL: 125dB

JVC HA-MR77X max SPL: 109dB

 

The JVC HA-MR77X is Hawaiibadboy's basscannon that started it all, and it can reach 109dB before distortion. Compare this to the reigning bass king, the SZ2000 which reached 125dB maximum before distortion. This 16dB difference is quite significant in terms of perception, determining the difference between an average loud house stereo and a front row rock concert:

The SZ stays true to the "Live Beat" design principle, where at 125dB it can realistically reproduce the loudness of drums at the moment of impact--the only headphones known so far that can do so.

 

One very weird fact: I could get the 77X to go as loud as the SZ!--but I had to press the cups real hard to my head. Apparently the drivers rely on a high pressure seal. Perhaps a vice grip mod to the 77X would work for the starving basshead, considering that they're only $59.

NOTES:

  • One-third of the total power of a 75-piece orchestra comes from the bass drum.
  • High frequency sounds of 2-4,000 Hz are the most damaging. The uppermost octave of the piccolo is 2,048-4,096 Hz.
  • Aging causes gradual hearing loss, mostly in the high frequencies.
  • Speech reception is not seriously impaired until there is about 30 dB loss; by that time severe damage may have occurred.
  • Hypertension and various psychological difficulties can be related to noise exposure.
  • The incidence of hearing loss in classical musicians has been estimated at 4-43%, in rock musicians 13-30%.
  • Recent NIOSH studies of sound levels from weapons fires have shown that they may range from a low of 144 dB SPL for small caliber weapons such as a 0.22 caliber rifle to as high as a 172 dB SPL for a 0.357 caliber revolver. Double ear protection is recommended for shooters, combining soft, insertable ear plugs and external ear muffs.

Statistics for the Decibel (Loudness) Comparison Chart were taken from a study by Marshall Chasin , M.Sc., Aud(C), FAAA, Centre for Human Performance & Health, Ontario, Canada. There were some conflicting readings and, in many cases, authors did not specify at what distance the readings were taken or what the musician was actually playing. In general, when there were several readings, the higher one was chosen.

Yes I have.

It's cut from the same cloth as the senn hd 25 (on ear) Dj types.

Nice cans. Small drivers. 

Post a vid bro. This is the Extreme bass thread:D 

 

 

 

 

 

 

 

 

 

the 77's are using "3 Kinds of Bass" track and sz2000 using "Worlds Deepest Bass"

 

Both off this vid. This vid contains both test tracks
