Bests & Worsts Reviews from Amazon

I have a Bose SoundDock that I got 9 years ago, and I haven't used it in a couple of years because it is an Apple 30 pin connector, and all of my iDevices are Lighting connector now. It doesn't have auxiliary in port, or I would have hooked an Airport Express and played music through it that way. I thought that I had a $300 paper weight on my hands until I found the CoolStream Duo. It works great! As soon as I received it, I plugged it in to the Bose, opened up the Bluetooth Settings on my iPhone 5s, paired them, and stared playing music. It works like a charm. I have a typical wood frame single family home, and I walked around the house while the SoundDock was in the living room, and it never lost the signal, even when I went downstairs and in the garage. The distance that the signal reached was very impressive. I was concerned that since this was Bluetooth, not Wifi like an Airport Express set-up, I would have to stay in the same room, but that was not the case at all. The other nice thing about this is that you can control the devices volume from your iPhone while you are playing music. I set the Bose volume to max, and then control the volume from my phone. I easily paired my MacBook Pro, iPhone 5s, and 3rd gen iPad, and played music from all of them on the Bose. It has another feature that you might not use often, but it does add value in my opinion. The Duo has an auxiliary out port that you can plug into any radio that has an auxiliary in port using a 3.5mm Auxiliary Jack and play music through that player as well. This would make it work with any device that doesn't have the Apple 30 pin connector. While it is plugged in to the 30 pin connector, it is charging it's internal battery, so you can take it with you and play it through other devices with the 3.5mm Auxiliary Jack wire. They say you'll get 4-5 hours, of play on a full charge, but I did not test this. Overall, I strongly recommend this product.
