Perfect in combination with Logitech Wireless Speaker Adapter

I was looking for a solution to use my speakers have no son and connections to be made each time with my iPhone, my iPad, and of course with my computer windows 7 Asus X5DIJ.
So I buy the Logitech receiver mentioned in the title to make my wired speakers "Bluetooth" and the famous adapter in question in order to make the computer also "Bluetooth".
To install, open the blister pack, read the instruction manual that makes 4 lines but is very clear, install the driver CD, plug the adapter and presto everything works in about 3 minutes if you do not have CD / DVD player, no problem drivers are available online.
At each windows startup, it takes 10 seconds and 2 clicks from the desktop shortcut (which I recommend to leave) so that the connection is made.
The sound quality is absolutely not degraded by the bluetooth link.
