I really can't understand the bad reviews for this item, especially those saying that it won't work with windows 7. I use windows 7 and as soon as I plugged the dongle into a USB port it was recognised and the drivers set up. I use it for a pair of bluetoot earphones and it work perfectly.
I bought these to listen to music on my laptop. I have a pair of Sennhisers but the lead is miles too long and I find it annoying. At the same time I bought the Daffodil 06J - Bluetooth USB Dongle to use with them. The two work perfectly together. The earphones are very light but give quite good sound quality, in fact I was surprised at how good they are. At first I thought they didn't fit but then realised that they fit round the back of your neck and not over the top of your head. It wasn't too difficult to pair the speakers and the dongle (which Windows 7 recognised immediately).
