very light and comfortable to wear...probably the best thing about these headphones! sound quality is so-so. I get a LOT better from my sennheiser cx-300's. not very sound-proof..they leak sound and do not really block out much when you're wearing them.
I got these because I find wearing my sennheiser's for a long period of time can be quite uncomfortable and wanted something that could solve that problem (over ear headphones) and still consistently deliver good quality low and high frequencies. The MDR XD200's do deliver when it comes to comfort, long lead, style and weight , but the sound is not so impressive. It distorts when you push the volume up just a little and the bass is very disappointing and does the songs no justice.
The price is reflective of the quality you get....my advice...spend a little more and get better quality headphones!!
