I need a close back phone to use in the lounge when others around. I simply use them plugged into the phones output of my Naim Supernait which had a HI Cap DR power supply.(I mention this because the addition of the power supply changed the sound of the phones out quite substantially)
I have been very pleased with these phones. Initially I founf them a little bass heavy and felt some of the detail I was used to hearing from my AKG and Sennheiser phones had been lost. However after a few weeks burning in and perhaps more importantly my hearing tuned into these W 1000's the details was all these with a surprisingly wide soundstage for closed back phones. These phones make for relaxed listening over long periods of time, the lack of 'in your face' detail I think makes them less fatiguing. If the room is completely silent then others can hear some slight leakage from the phones. However if there is a radio of TV on then I can listen to my music without disturbing others.
I have no problem with the headband find it comforatable enough and the phone not that heavy. If I could buy real leather replacement pads I would get them but otherwise no complaints.
I listen to pretty well all genres of music Jazz/Folk/Country/Classical/Rock/Prog Rock and these phones do well for all. If you need closed back phone then buy with confidence.
However search the web for best deals especially if your a Uk buyer as they expensive here. I purchased mine from Hong Kong back in 2011 at £399 and you can do at least as well today.
