For detailed information about the problem see: http://www.jensign.com/S4Distortion/

The issue is CONFIRMED FIXED with I9505XXUBMEA firmware. I expect future updates for other regions should have this fix.


ORIGINAL POST:
Anyone having issues with audio crackling/distortion when using headphones?

It seems with audio volume above 50% using UE600 headphones i get crackling/distortion(usually on bass) that gets worse as i increase volume. I've read other reports of similar audio issues with decent head phones but not sure what the issue is.

I tried stock, cx-270 and koss headphones but they don't display the issue.

I've tried the UE600 on a SGS2 and notebook so far and no crackling/distortion.

So far i've read 3 people have confirmed crackling issues that are bad enough that you cannot listen to music.

Details:

JVC FXZ100 and UE 600 headphones have issues with crackling relating to bass.

stock, cx-270, re0, koss pathfinder, sennheiser ie8 and CX-500 appear to have no crackling.

My UE600 crackles at volumes 10 and above.

---------- Post added at 04:46 AM ---------- Previous post was at 04:07 AM ----------

I was thinking this is an issue with low impedance headphones?

The UE600 is 13ohms which is pretty low. JVC's is 16ohms.

EDIT: But the CX-270 is 16ohms as well. Very strange.

I did some more testing at a local store, and found one unit that distorts heavily above volume 7 and another that does not distort at all even at 15!


so I went to do a 1 to 1 exchange but unfortunately the new unit I got distorted at volume 7 too! and it was much noisier. So in the end I decided against exchanging.

It's a frustrating problem though.

Mine is on MDE.

I wonder if this issue could be addressed in software? If it's a hardware issue I have little hopes of it being solved I guess...
