I have this, it's not in your price range, but it's fookin good, mate.

Comfortable, holds itself well, has 2 hatches for USB and headphones, and the back comes off, allowing for realcontrol thangs if you're into em.

Seriously though, its good.

That's a, ridiculously, overpriced Shinecon. Destek slaps their name on a number of headsets.

Cheap ($20) and works great! And its comfy with good leather padding and support straps.

These are sold pretty much anywhere and are compatible with many phones, I've heard good things about them.

One downside is that there aren't any buttons on them, so you'll need to use the tin foil method or a bluetooth controller for Cardboard stuff.
