The BH-503 won't win any awards for audio quality, but they do a fine job regardless. Handsfree calling via Bluetooth is excellent and the ergonomic design means these are comfortable to wear for long periods.

Although the sound quality is better than adequate, it's not fantastic. Our main concern is that the audio lacks substance.

While these headphones are decent for bass heavy music their harsh, bloated mid range makes instrumental music difficult to listen to.

The Plantronics .Audio 770 is an excellent set of PC headphones that's sure to impress.

TDK's ST-200 headphones won't blow your mind with their sound quality, but they offer an affordable upgrade from your stock ear buds and are nicely designed as well.
