There's a little difference depending on the source, and the volume isn't as loud as earbuds but overall I'm very satisfied. Enough that when I dropped and boke my first pair I went and bought another the same day. I listen to music and video from my iPhone, two bluetooth broadcast adapters and a dongle for my laptop and all of them give me adequate performance through the headphones. Give them a try, I think they'll suit your needs.

Bear in mind I don't try to stuff these under a helmet and ride with them, they are for running, watching movies on my laptop and listening to music from my laptop/phone/iPod (through an adapter) while sitting or riding in a car. I would imagine they wouldn't work at all for riding.
