beyerdynamic T50p

DISCLAIMER: I've not listened more than 20 hours on them.

If these headphones doesn't tur water into wine during the next 80 hours of listening, I declare these headphones as the worst buy ever. 

The first time listening to these headphones left me with an impression of bad bass and great vocal quality. My hope was that the bad bass would turn into at least acceptible levels after a while. This has not happened. Also, the vocals, to me, sound like played through a tin can. 

Do not buy these unless you only listen to bad music. 

EDIT: After two weeks I finally squeezed some bass out of them, but only after careful placement on the ear. 2 millimeters off and they sound like crap again. So I nudge the sound quality up one step, but still, they are not very good.

I'm using the T50P with my Centrance Dacport in my office and I'm in paradise. I did the usual burning of about 150 hours and used them every day since and can only praise for the amazing SQ I'm getting. I was a bit afraid of the sizing issue but didn't have any problem finding the proper adjustement and positioning is not an issue. listening to Radiohead, Jesse Cook, Yo-yo Ma or Marillion is just fantastic. I even favor them to my DT990/600 at home.

Enjoy!
