         easy man , take your time , hope these things are not taking a toll on you , i know its quiet stressful , huge archive of reviews , responding to everyone , job  and commitments are like living another life with in this small life , take your time , just take it easy :) .

Not that I can think of, unless you require ridiculous levels of bass or are sensitive to treble unevenness. 

 

 

Suppose I did require ridiculous levels of bass, what would you recommend me?
And treble unevenness? Could you elaborate on that a bit? I don't really know what that means. :p

For more bass than the GR02 you'd have to look at something like the Sony XB40EX, MEElectronics M31, or Padacs Aksent.

The GR02 has a somewhat 'hot' top end and can accentuate treble sibilance. Some people are sensitive to this and will much prefer something with a flatter or more laid-back treble presentation.

Joker how do you get to trial so many different headphones?

 

Do you have industry contacts or do you just buy / sell a lot of different headphones?

 

Sorry for being nosy I am just interested how you get so many headphones lol.

Since I don't think starting a new thread would bring anything useful:

Which IEM do you consider the most extended (bandwidth) of all of the universals?

Would any of these be suitable for deep fit and have slim build an/or narrow nozzle, preferably working well with foam?

 

Dynamic drivers or moving armatures are preferred.

 

Current list is perhaps:

VSonic GR01, Etymotic MC5, Fischer Audio DBA-02 mkII, Etymotic HF5.

Also probably j-phonic K2 SP, once the site is up.

While Westone IEMs isolate well, they are too dark for my taste.

I would think that it's a bit weird to ask that. The high frequencies are relatively easy to reproduce, so it would only be a question of how low the bass extents.
While bass extension of IEM's is definitely sub-optimal (compared to full sized headphones, or especially sub woofers), a lot of IEM's can still extent pretty far. Not that it really matters all that much, since our hearing is insensitive to low bass notes in any case.

You'd be suprised, most IEMs end around 18 kHz and roll off even earlier.

There are a bunch of IEMs that reach 20 Hz indeed with plenty of power, but the only ones I've tried that reach all the way up were SE-5 Reference custom and Hifiman RE-272 (never again, hardening cable went brittle and broke by the earpiece - also it's not suitable for deep fit).

So what if it rolls off at 18kHz?
Those frequencies are pretty useless, if we can hear them at all.

With small drivers reaching all the way down to 20Hz is not really necessary either. Those are frequencies that you feel much more than that you hear them. And there is no way you're gonna feel them with such a small driver.

Imo decent extension from 40-16kHz should be plenty for an IEM.
You should be worrying more about other sound quality factors more than bandwith, if you ask me.


Wanting deep extension is completely fine with me, but in my personal opinion other factors are simply more important.

Maybe more like 15hz - 18Khz would be optimal...

 

Unless you are a bat or a dolphin or similar then you will not be able to hear anything higher.

Except if you haven't destroyed your hearing and can hear 20-20 still. Which I happen to.

(Pity my eyesight is nowhere near it.)

 

The highest end is audible as "air", also helps with soundstaging and positioning.

 

Amended list of deep fit IEMs:

VSonic GR01, Fischer Audio DBA-02 (and mkII), any Etymotic.

Anything else that sounds nice? I'd prefer non-lean if possible.

No it doesn't.
Not to be snobbish, but I have seriously studied a university text book on psychoacoustics, so I should know.

>16kHz information is identifiable, and does add something to the overall timbre of the sound (though very subtle). However, removing it wouldn't change the fidelity. It would just make it sound 'different', with the listener having difficulty pointing out just exactly what is different.

I can hear and feel it just fine down at 15Hz (or 12Hz for that matter) with my IEMs (Philips SHE3580) L3000.gif

 

Have you actually tested the extension on the two ends of your headphones with something like Sinegen?

I haven't tested it myself, but I suspect that what you're hearing at those frequencies are the distortions of the driver.
I.e. you're probably hearing harmonics, rather than the fundamental itself.


I'm sure you can feel it. I can too. But in my opinion that is definitely not the most important factor for good sound quality.

Clearly astral has superior hearing ability and a greater knowledge than most normal people so do not dis-respect him. He is the dolphin man.

Putting it that way is simply rude. Please refrain from doing that.


I'm not trying to ridicule anyone, rather I'm attempting to be helpful and share my knowledge. If that is not appreciated, I can leave this conversation.
