I’ve been testing the BT400 G5 Bluetooth Headset from Radtech (a sponsor of this site) for a few days now and like it. The BT400 connects to virtually any Bluetooth phone (in my case a Treo 650) and allows you to talk handsfree and remain in compliance with many local laws for using your mobile phone while driving.
The BT400 weighs 20g, fits me perfectly and works well. The rubber earhook is easy to switch from right to left ear operation. It’s slightly larger than my other headset (Motorola’s H500) so it may not be a good choice for small ears.
Pairing the BT400 to my phone was easy and sound quality is clear – no one I spoke to could tell that I was using a headset. Rubber ribs on the outside of the BT400 contain buttons for power/mute and talk/transfer, but sometimes it is difficult to tell the buttons from the ribs.
The volume buttons makes the BT400 loud enough to hear the caller clearly – which is more than I can say for the H500 which is barely audible sometimes.
The BT400 G5 Bluetooth Headset is available in light blue (Dolphin), silver (Marlin) and black (Sea Bass) for US$65 from Radtech. A USB charging cable is available for US$6 extra.
