Our take on the Sennheiser PMX 90

by Dave Bar

The PMX 90 features an ergonomic neckband for a comfortable and secure fit. The single-sided cable reduces tangles so you can be wrapped up in your music and not in your headphone cord. The soft, lightweight earpads make these 'phones a pleasure to wear, even during long listening sessions. And best of all, you'll enjoy clear sound with rich bass from your favorite portable music player.

Crutchfield Customer Review (What's this?)
all i could want in a portable headphone set, lightweight comfortable good sound-- the coolness factor is in the manufacturer "sennheiser" quality not the follow the herd of the "dr dre phones". affordability too.
good sound quality,crisp clear--comfort fit-does not totally cut off all outside sound so it is safer than total ear covering headphones
lightweight but can bend out of shape if one is not careful

They are very comfortable. I use them when I go jogging every weekend approximate 5 to 7 miles. For me it was perfect choice.
