CoolStream Go Bluetooth Adapter for 30 Pin Bose Sounddock and Motorcycle Cables for Wireless Music Streaming NOT for Cars. NOT for Harley Davidson.

I have a Bose, non-BlueTooth speaker system that I absolutely loved the sound of, but was tired of dealing with the corded connection. Only one of my source devices was Apple, so the 30 pin connection didn't work for most of them. I always have used high quality corded connectors (3.5 mm stereo mini) to maintain the highest sound reproduction quality I could, but the inconvenience always had me using my inexpensive Bluetooth speakers (with inferior sound) just to have the flexibility and movement.I will admit, the first Bluetooth adaptor I purchased was NOT the CoolStream Duo. I had already purchased and used a Universal/generic Bluetooth adaptor from my local "Big Box" electronics retailer, paying the same as the the price of the CooStream Duo. While I did gain the convenience of no cords with the generic version, I felt it lacked a bit of quality (over the high end corded connections) with some noise being picked up in the higher frequencies. This could have been caused by the low quality built in "pigtail" required with the generic unit, used to plug into the 3.5 mm Stereo mini plug, or simply inherent in the design. Battery life was +/- 8 hours, but the charging had to be done using an entirely different USB adaptor from anything else I owned, and was inconvenient.I saw the CoolStream Duo on Amazon, and the description seemed to be perfect for what I wanted. It claimed to plug in directly to the Bose Sound Dock using the built in IPod 30 pin connector, not use a cord to run to the 3.5 stereo mini, and also appeared that it would charge itself using the battery power (or AC power) of the Bose unit itself. I MAY have been a little skeptical about the ease of operation, but if $30 could turn my inconvenient, yet wonderful sounding Bose system from a virtual boat-anchor into my go-to speaker system, it would be well worth it.So how did the description provided live up to real life? Absolutely on track. No oversell, no hype. I am not a super techno guy, average at best, and I went from opening the package to playing music in about three minutes. Could have done it a bit faster but they used REALLY good tape! The unit charges in place, as advertised, I assume simply by drawing power from the 30 pin connector on my sound dock. All the controls from my phone translate into the appropriate action on the speakers, and the range is equivalent to other BlueTooth devices I own.The convenience of the Coolstream basically merging with and becoming part of the Bose Sound Dock is fantastic. I only have one thing to grab, it doesn't "fall off" or dislodge.....and the sound? I have noticed ZERO added noise, sounds as good as having the source device plugged directly into the 30 pin, and cleaner than having to use even a high quality 3.5 stereo mini cord - including Monster Cable or Gold Ends.I have only had for a month now, but so far I can give the Coolstream Duo five stars - no hesitation!

With broad range of offerings for Bluetooth receivers, selection of the good one may be difficult. CoolStream stands out from the crowd in few ways:- compact. You do not get wires, power adapters tangled around - just ~1.5 in square unit itself.- easy to connect. Both iOS and android devices see it immediately and pair within couple of seconds- easy of use. With multiple phones/tablets you may want to connect, switching from one phone to a different one may be an issue - devices do not pick the right one when you turn them on, so you have to grab the "wrong" phone, disconnect bluetooth device there, than connect from the phone you intended to use. With CoolStream, as long as no other device actually plays music via CoolStream, you can go ahead and start playing.- reception range. Out of 3 "current" devices I have recently purchased and 2 older generation ones, CoolStream definitely strongest in this respect: being placed at far end of the house it gets signal from any point of 1500sf house, from as far as 50 ft with no line of sight (there are 2-3 walls in between phone and receiver). After seeing other BT receivers dropping signal from 20 ft with minimal blockage of the line of sight, this is pretty impressive.I did not observe any disadvantage so far, beside it requires 30 pin Apple connector to sit on - so you need an appropriate "host" device (or adapter cable which kind of defeats the purpose of being free of wires ).CoolStream has ability to connect to any device via plain audio cable and work from the built-in rechargeable battery, but I had no chance to test how well it works. Sound quality via 30-pin adapter is great as expected - but it is all digital so no surprises here.Overall, highly recommend despite some price premium - it does worth extra $$.
