I recently did some repairs on my sennheiser hd 555s and I use them now and I can hear a differense in the sound from what it was before. IT sounds like certain noises are very quiet and some sound normally. But generally the drivers are perfectly fine.
I also went to http://www.audiocheck.net/soundtests_headphones.php and checked the wiring section; the centred and twisted sound files sound opposite of what they should be compared to normal headphones.
It seems that I need to switch the polarity of my headphones, so I checked around and http://www.ehow.com/how_8498401_switch-polarity-headphones.html is the only thing I found, but it didnt work. (why?)
Is there anyway I can switch the polarity in my headphones? any wires to solder? help! Am I wrong in thinking that I need to switch the polarity?
I can post a pic of inside of my headphones if you want.
