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

I use this on an Altec-Lansing speaker unit that has the 30-pin plug, design for you to sit your old iPhone or iPod on it. That unit sounds really good with its subwoofer so I hated losing the ability to use it with the new iPhones. Popping on the CoolStream is now a dream come true. Connects right up and does what it's supposed to. You will need one of the older 30-pin cables to charge this unit off of any USB port or even the Apple charger, but if you don't have one of those older cables laying around, you can pretty much find those in the impulse aisles for 5 bucks in every store from Walgreens to Ace Hardware, they're all over the place.One thing I want to mention: I had a problem one day where the music would cut out and come back on every 3 seconds or so. That happened with another BluTooth adapter I tried, I thought it was the adapter. Not so, it's the BAD memory management in the iPhone. They only come with 1GB ram, and often most of that gets used up. I have an app that shows available ram and it's usually down to 6-10MB available (not a typo) with only a few apps open. So I cleared my memory, tried playing music again and it worked fine all afternoon. So if you have that issue, close your apps, but the important one is to close ALL PAGES in Safari before you close Safari. If you just swipe up Safari to close it, all of your open web pages stay in memory and eat it up. I'm pretty ticked, $950 for an iPhone 6 Plus with 128GB storage and STILL only 1GB ram? ASpple has no excuse and it's not like they can't afford to up the ram in these things. ANYWAY, this CoolStream is awesome and make sure you have apps closed down once you start streaming with BT and it'll work great.

I highly recommend this product! Here's why. For over three years, I had been using my iPod Classic with a Bose SoundDock Portable both to relax in the evening and as my morning alarm clock. After several years of faithful service, my iPod Classic stopped working, so I went to Best Buy to find a replacement. Unfortunately, Apple no longer manufactures the iPod Classic, nor any version of the iPod which uses the 30-pin connector that the Bose SoundDock Portable requires. I contacted Bose's customer service department, and the representative with whom I spoke asked if I owned a smartphone. I replied that I had a Samsung Galaxy S5. Bose's customer support representative suggested that I purchase a Bluetooth adapter for the SoundDock Portable and that I use my smartphone's music player as a replacement for my now defunct iPod Classic. He cautioned me, however, to shop carefully for the Bluetooth adapter, as there were several on the market, many of whom were not very good. I did as I was instructed, and found the CoolStream Duo.The CoolStream Duo is very easy to use; just plug it in. My Samsung Galaxy S5 paired with the adapter without any problems, and the standard music player app on the S5 works great. The alarm clock function on the clock app also works. I did have to upgrade the micro SD card I was using with my S5 to one that is large enough to hold my entire music collection, which is greater than 80GB. Even so, I now have the functionality of my old IPod Classic for less than half of what it would have cost to replace it.I also tested the CoolStream Duo with a Klipsch iGroove SXT iPod docking station that I use for travel. Again, it worked flawlessly. Hence, I will be purchasing a second CoolStream Duo for traveling.If you need to replace an iPod Classic, you can't go wrong with the CoolStream Duo and a Bluetooth-capable smartphone.

This product is excellent. It works like a charm. I've had it since 2015. And it still works. The only detail is that the battery can bulge and get damaged, and all you have to do is cut the battery cables and it can be used with direct energy, with a USB and the plug. I recommend it.

Decided to go bluetooth after my last OS update on my iphone 5 which seemed to have disabled my audio out through the lightning port (at least in my car. It works at home through my computer and stereo). Did some research on line and found other people had the same issue. The fixes were all mixed so I decided to find another route, which was to go bluetooth. With a little research I chose the Coolstream adapter and so far, it's nice product that works pretty good.Works with my in car pioneer stereo which has a 30 pin dock connector. The sound is not as crisp or full as a direct connection but it's pretty good. I do have to turn up my stereo louder with the pioneer audio volume control (And yes audio is turned up all the way up on my iphone), so I do get some hiss. It's not noticeable when the music is playing but when there is no sound it's there...not annoying or anything but there is some background hiss. I may have to adjust volume on my iphone and just turn the volume louder on the pioneer head unit to seem if I can eliminate more of the hiss. But it's not really a bother when I'm listening to talk radio or music.The device itself seems a little light and not incredibly durable...at least it doesn't seem that way. But overall it should last as long as one is careful.Overall it's a convenient option until I can figure how to restore audio through the lightning port to 30 pin wired connection. It's bluetooth so I am aware of the audio compression limitations. But the sound is pretty good and the connection is easy and steady with no dropouts. Overall a good product that gets the job done.
