I am not a fan of these bluetooth one-ear devices in general, because I cant walk down a street without getting weird looks from people who cant see the device on the opposite ear. I have now restricted the use of it for the car, and this device is great for this. It das 125 hours standby time and 4 hours talk time, and only weighs 23g, which is light enough to forget about it whilst driving. It is small and compact and works great with my Sony Ericsson W910i mobile phone, however I am told on the website that it is compatible with other manufacturers phones that have bluetooth.
It is a simple and easy to use device, which is necessary when on the go. One of the best features of this product is the ability to change the colour of the cover of the device. It can be changed into five clours: Black, red, green, blue and orange. It can work from a distance of 10 meters away from the bluetooth device.
As i have said, I do not particularly like these devices, and you can only attach one bluetooth device to it at a time, but aside from that it delivers great audio sound and gets the job done. A good product!
