Hi,
I wanna ask something..
Recently, I feel that my AKG K702 sounds different..
 
The left side sounds more bassy..
However, the right side is concentrated more on highs..
I just noticed it a week ago..
 
is this can  broken or is it normal for this can in order to build the soundstage?
 
Thanks in advance!

It sounds like you're listening to a 1960's era Duophonic record.
 
How long have you had them?  Did something happen to them?

I think around 6 months.. nothing happens i think.. I just plugged it in headphone amp..
The clarity is still there if u put on both sides..
Do you know any soundtrack (for benchmark) that has equal balance on right/left side? It may help me to confirm it..

Any mono recording should work.
 
Could it be your headphone amp?

I guess no.. since I have two amps. and I have changed to both.. it sounds the same..

I believe the AKG warranty is 2 years.  So you should be OK, if you bought them new...and kept your documentation.

Agreed, any mono recording.   If you turn it up, is there any rattling or anything going on?
 
You may want to pop the pads off and make sure there's no hair or dirt or anything on the driver.

Well, yes there is sound of rattle if I turn the volume up/down.. is this the sign that it is broken?

That is a possibility.   Make sure the recording you're listening to sounds clean on another speaker/headphone.  Is the rattling only on one side? Also, remove the pad and make sure there is no hair that is against the driver or protruding through the fabric between your ear and the driver.   If hair is touching the diaphragm that can also cause buzzing/rattling.  Otherwise, it could be damaged and should be sent for warranty service.
