Are there good quality headphones (both ears) that work with cellphone, computer and iPod?

I’d like to have *one* headset/headphones. I don’t mind if they’re over the head, around the head, with a boom, whatever, as long as they sound good and work for everything, even if they require an adapter.

Everything means:
Cellphone 2.5mm
iPod (standard headphone jack)
Computer (standard headphone jack + standard mic jack) OR USB

OR all bluetooth.

Thanks!
