I had heard a lot about bluetooth, but had never really investigated its capabilities. What I was looking for to pair up with me Samsung D600 was a hands-free head-set that would be comfortable. With the MP3 played in my phone, I had tried those (wired) headphones that plug in the ear with a clip behind and found it most uncomfortable to wear for long periods of time. Then I came across the WEP200 Samsung bluetooth headset on Amazon and ordered it. I was not disappointed. Combining comfort, trust and flexibility it gave me total freedom when talking on the telephone. The only think I did find disconcerting at first was when walking along the street, it appeared that I was talking to myself, because the headset is to tiny! Weighing less then 10g, the WEP200 uses Bluetooth 1.2 provides up to 4 hours of non-stop communication and 100 hours on stand-by and has a radius of 10 metres having an in-built microphone.
