I was very much in two minds as to whether or not I was going to buy this product, purely because there were so many contrasting reviews regarding the quality of the sound of the product. This product is much cheaper than the alternative Logitech version of this, which seemed to be better than this Belkin one. Logitech Wireless Speaker Adaptor for Bluetooth Audio Devices
This Belkin receiver is also much smaller.
After much thought I came to the conclusion that based upon my positive experiences of Belkin in the past, and for the fact that I could send it back if it was crap, I was going to buy it. After it arrived (in just two days!) I was eager to plug it in and get it going and this only took a couple of seconds and was very easy. (The instructions were very clear also).
In terms of the sound quality, I have to say that paired with my iPhone 4s, the sound is just as good as when I plug it in via the AUX cable! It also works within a reasonable range, although does cut out if you're standing too far away (obviously). The product is also very compact in size and looks great on top of my stereo.
Please do invest in one of these! Brilliant price, sound quality and overall aesthetics, ergonomics and practicality!
