Shoreline Music is my go-to retailer for Audioengine products. They have excellent pricing and always include a personal card with every order. I will be doing business with them for years to come.
The sound reproduction from the B1s rival the Arcam receiver I have. I like the size and the ease of use of the B1. You will not be disappointed and will bring your hi-fi setup to modern standards via bluetooth.
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.
