It is good for listening to music, but as the headset rests on the ears and does not enclose them, the sound experience can be somewhat impaired. The battery definitely lasts more than 8 hours.

Sounds pretty decent as far as I can compare. :) But it still can't be compared to over-ear headphones like the Bose... I find 8 hours at a time a bit exhausting because they fit me (with a big head) a bit tight. Qualitatively, however, great for endless Telcos. :) Would buy it again.
