Genius HS-920BT Bluetooth Headset Video Review
 

"The Genius HS-920BT Bluetooth Headset provides good value for money. It's lithium ion battery can play 7.5 hours of continuous music, or provide 9 hours of talk time. The unit comes equipped with 40mm drivers and a frequency response of 80Hz to 20KHz. The headset is also light as a feather, which is good if you're a ninja laying in wait to assassinate someone and you want to pump out Queen's "We will rock you" before heading into battle." ~3dGameMan.com
