The tech website Review Horizon has tested out the CoolStream Duo.
Review Horizon put the Duo through its paces pairing it with several phones successfully as well as trying it out on a favorite portable boom box. Being able to take your music out doors or on the road is one of the best new features of the CoolStream Duo and the sound and quality did not disappoint the reviewer. The no-pin pairing and ease of use was a big hit as well.
The Conclusion from Review Horizon is:
The CoolStream Duo Bluetooth Receiver adds Bluetooth compatibility to virtually every audio device currently on the market today, starting with the obvious 30 pin capable iPhone/iPod docks and extending to Boom Box units, Audio Receivers, amplifiers and many cars.
