I have had the HD650 for a few weeks now....
I have tried everything to try and rule out a channel imbalance for example :
Play at extremely low volume on mono to see if one sides goes silent first : no result both seem the same...
Play the headphones in mono mode....
Use switch channels on foobar....
Turn the headphones round, switch cables, tried in various positions on head etc...
None of these things have conclusively proved either way but the problem which is irritating me and somewhat spoiling my enjoyment is that everything seems right side dominant.... The headphones seem to always sound right sided about 80% of the time.... I am not sure if this is how I perceive the soundstage or maybe the headphones showing up how tracks are recorded... But it is annoying me... Has anyone else noticed this?
