Um, I need a substantial one for daily call. I seached a lot of headhpones and can't choose between those two. One is BT3030 Bluetooth Stereo Headset. It's 20% off now. Only $29.59. It supports 2.0, V20., V1.1, V1.0. And the operating range can be up to 10m. The best feature is 230 hours' standby time. Another one is Earhook Wireless Bluetooth Headset. Only $14.23 with 20% off. Standby time is 130 hours. Operating range is 3-10 m. It supports bandbluetooth 1.2. It is wireless and cheaper. Anyone can give me some words for it?
Update: The link to the bluetooth.I'm still waiting for help. BT3030 Bluetooth Stereo Headset Earhook Wireless Bluetooth Headset
