Bought this to pair with some AudioEngine A5+ speakers I also purchased from Shoreline. Plugged it in and no issues pairing it with my iPhone 6s, Kindle HDX or a Samsung S4. It can only be connected to one device at a time, so for each new device, simple press the lit button on the front and it immediately show on the new device. I do wish it had an on/off switch but that is not a big deal. Range is outstanding and I have never had a single drop or skip. Highly recommended.
