Input:
These is the most comfortable headphones I've used, and I've bought and used some very nice ones. I wear glasses and regular headphones become painful after 30-60 minutes. Ear plugs trap moisture in the ear canal and that's uncomfortable after a few hours. While it may seem nothing will make me happy, these headphones do. I've used them for several weeks now, and I'm still happy.

Edited March 2015:
I bought these March 2015 and love them as much as the MDR-W08L:
SONXTRONIC Xdr-8000 Vertical in Ear Ultralight Sport Running Headband Headphones

$25 is fair, quality seems good, them wear the same. I love them as much as my beloved Sonys, and I love my Sony MDRs very much..
