Perfect! (Windows 8.1 iPhone, headphones)

Connected and works perfectly on my Windows 8.1, a USB 2.0 port (Did not work on a 3.0 port). No updates, no drivers, not even the installation CD. No problem with the sound, I connected my wireless headset Peugeot, I was even able to connect my iPhone and is found in bluetooth, really perfect.

I just insert the USB plug, search the Bluetooth function in the Control Panel of the PC, and my iPhone and my helmet was found.

I also received an email from the manufacturer when purchasing connector, telling me to check the compatibility in case and to take a tour on their site, so really serious!
Note that on WIndows 8.1, I have nothing to install, but the site there are drivers for WIndows XP / Vista, try it out if it does not work for you:
