Unscrew the brass back plug:   Insert cotton into the chamber and tune the bass. Unscrew the back brass plug and open the body, insert cotton into the chamber.  I can unscrew it with my fingers, this avoids damaging the brass plug.  You can fine tune the bass amount and characteristics to...

400+ hours of JVC HA-FX850, with upgraded cable, bass is correct, extended and not too much at all, really nice to listen to.  In my memory, 100+ hours is not enough for the beast.  Cable is important for it.

I am in China too.  I made a replacement cable.  PCOCC+Silver instead of OFC cable - made the sound much darker and smoother, definitely improvement, not cheap.  The earphone is very reasonable though ( about 225 USD).  OFC and gold plated cable is not my book anywhere, they are too thin and...

I made a cable myself, with Oyaide Rhodium plated 3.5mm L plug, PCOCC+silver XSymphony cable, and ATL Gold/Silver/Rodium plated brass MMCX connectors.  Pure music enjoyment with Asus Xonar Essence card.  Beautiful and realistic sound, cannot say enough.  Very balanced sound, quick and accurate...

Wait for the surprise then.  Mine has been in use for over 300 hours now and it is a completely different animal than brand new.

When I first got the FX-850, the first impression is that it is as bad as everybody tells, the mid/treble is recessed, the bass is out of nowhere and does not bend with the rest of the spectrum, just like all of the sudden a bass wave slam into the head with so much energy that has its own way. ...

I just purchased a Goldring NS1000 noise cancelling headphone.  I do not use noise cancelling at home of course (I use the feature only on travel).  The sound is good, but kind of "distant".  After careful inspection (it is inexpensive), I found a piece of pad inside the ear cup, after removing...

I use OPA2132PA and OPA2134PA in my headphone amp and both sound great with my SRH940.  Changing the cable and connectors make the sound smoother, i try to avoid the SRH940 with gold plated stuff, they made the sound harsh silver is better in my book.

It is a monitor headphone, so being so detail maybe too much for some people, but I do enjoy the dynamics revealed in the phone.  With my "silver cable" change and Asus sound card, it is amazingly great with live recordings.  To me, the sound is very real.

I am glad somebody else found it too, there is nothing to steal anyway.  I already bought it so it just make it more fun!

I think the author is just being sarcastic.  More importantly, if you cannot hear the difference then nothing matters.  If you can hear the difference then all things matters.  I DIY all my gears including the cable used to the earphone, almost anything in between.  Why am I doing it?  Reason is...

I am not a scientist so it is only my guess to get me to try it.  Sound do interfere, it can be confirmed by speaker cabinet design.  How much it did I don't know and I cannot explain it exactly.  I am listening to my SRH940 now and I know it is quite amazing.  It feels like a different earphone...

Quote:    The cotton is absolutely necessary.  Just placement of the ear cup does not get the same result.  If just stuff a strip of cotton behind the ear, between the ear and the ear cup, try to fill it up.  This is to prevent the sound pressure injected inside the rear chamber to...

Today I thought about why SRH940 may feel like lack some bass.  The bass wave inside the ears are projected into the front and back of the ear of course the ear becomes a divider inside the ear cup.  So I put a piece of cotton behind the ear and move the ear cup forward therefore there is not...

Quote: Yes that is the point.  I believe the ability of SRH940 to produce the detail is the superior mechanical rather than anything else.  Or course it is not perfect, but over all I appreciate the details the headphone is capable of.  Treble leaning maybe but that is not detail.    

I completely disagree that detail comes from more treble.  That is absolutely nonsense.  The detail come from accurate frequency reponse AND phase response, and controlled behavior of the sound reproduction.  Details CANNOT be "produced", they are "reproduced", or I should say "revealed".  They...

I have got a set and listened for a while.  After about 100 hours of burning, the sound is coming out.  I always replace the Shure cable whenever I can.  The original OFC cable and gold plated plug is not bad, but the sound is always too "pushy".  I replaced with a Sennheisser  silver cable with...
