I had the opportunity to play with Audioengine W2 Premium Wireless Adapter this weekend. This device allows you to use your iPod/iPhone for total wireless music control. The beauty of this device is in its ease of use and the fantastic sound quality. The setup couldn't be simpler. You plug the sender unit into your ipod/iphone, then plug the receiver into the audio inputs on your music system then turn on your ipod/iphone. Within 30 seconds the sender and receiver find each other and you can now choose your song or playlist.
The W2 uses Wi-Fi technology to deliver the signal without any dropouts, static or interference. The sound quality was as good as when my iPod/iphone was connected to my system with cables, but I had the advantage of being able to wander about my living room without being tethered to my stereo system. I was even able to sit on my front porch and change my music selections! The advertised range for the W2 is 30ft, but this may vary depending on walls and other variables. Although the W2 does not advertise that it will work with the iPhone, I had not problems with the setup except for the annoying warning that "this device is not designed to work with the iPhone".
My overall impression for the Audioengine W2 Premium Wireless Adapter was excellent. If you're looking for a device that will allow you to play your iPod or iPhone through your music system wirelessly, this is the device to get.
