since my laptop’s audio port got messed up in a bike crash last year, i got this thing… problem fixed + less wires!
Got it from amazon.co.uk for about £25. Since i had never used my laptop’s bluetooth, i had to install some drivers first but after that it worked pretty much out of the box… you set it up once (click a button on the adapter and then click search for bluetooth devices on the laptop) and after that it just works.. even reconnects when restarting pc. no problems with the connection (its a few meters away in the other end of the room) sound quality seems to be the same as with the wire. Overall, its a neat purchase for a fairly cheap price so im a happy camper :)
