Overview
The BT400 G5 makes good first impression. It is stylish and light. To get started the Bluetooth headset needs to be charged for 2 hours. 250 hours standby and 5 hours talk time should be possible with this headset. Pairing is easy. I just press the power button on top for seven seconds and the indicator LED starts to blink blue and red. On the Sony Ericsson T630 I search for new devices and use 0000 as pass-code to finalize the pairing.
The new Bluetake fits comfortable. The ear hook can be rotated to fit left or right. On top are the on/off/mute switch and the talk/transfer button. On the left and right side are the volume controls. This distribution of buttons makes it easier to find the right buttons with my fingers. Some headsets have all buttons on top and its more difficult to press the right one.

I have a IBM Thinkpad X40 that has built-in Bluetooth, but I could not get it to support the headset profile of the BT400 G5. This is I think a general problem with the IBM Bluetooth software. The software that comes with the Bluetake BT007Si Bluetooth dongle supports the headset profile without a problem. The VT BlueSoleil Bluetooth software is actually quite nice. It shows all connected devices like a solar system (see screen-shot below).

Using the BT400 G5 on my mobile phone works well. The speaker is loud and clear. The microphone works also decent. I still would like to compare a bone-conducting headset. When using the BT400 G5 on the Notebook the quality is good for using it with VO|P services like Skype (Bluetake has instructions on how to use their headset with Skype). I used the standard Microsoft recorder to record some voice samples and those sound well too. Listening to music on the headset is of course possible, but the quality is low.

Conclusion
The Bluetake BT400 G5 is a stylish and comfortable Bluetooth headset that is very easy to use. To be able to use the headset without changing the pairing with multiple devices is convenient. My wife already snagged it, that says it all. The BT007Si is a great working Class-II Bluetooth dongle that comes with excellent software.
