I suggested that you can have a look at the Jabra BT8010 bluetooth headset, I like it , I have tried some other bluetooth headset also:
- Radio shack 2.4GHz Wireless Stereo Headphones
(Uncomfortable heavy kill your ears)
- Creative's SE2300 Bluetooth Wireless Headphones
(oh my aching ears...ouch!)
- Logitech FreePulse Wireless Headphones with Bluetooth 2.0 EDR
(very nice! 99.9% there, but, they must be worn upside down and without the ear hug. Although very soft the position of the ear piece digs in your ear and need constant adjustment.)
The Jabra BT8010 bluetooth headset with up to 300h standby time, and bluetooth 2.0 mono. The microphone is very clear.
And the price for it has dropped a lot, I got it for $55, but a recent deal on it is
$49 , you can have a look at it .
