Are you referring to an A2DP bluetooth headset to listen to music? Or a headpiece to make phone calls?

In case for A2DP, I bought some LG HBS-250 a year and a half ago (for ~$10 on a sale)

The sound quality is pretty excellent with different equalizer presets. Also, you can control the media player with the buttons (play, pause, forward, back, fast forward). Sound quality for phone calls is pretty good.

The only drawbacks is that after wearing them for 3-4 your ears start to hurt because they're over the ear, otherwise they're excellent.
