Review on Aluratek ADB1B Bluetooth Audio Receiver and Transmitter: 2-in-1 Wireless Adapter for 3.5mm, AUX, Optical Audio - Connects and Streams to 2 Bluetooth Headphones Simultaneously by Scott Adaymiln

I haven't seen previous reviews with pictures showing the size of the device, so I've uploaded some comparisons of the device with a quarter. I hope you can understand how small this thing is. It's quite a small unit but it has some great features, it works with RCA, optical and AUX, as well as dual bluetooth output in transmitter mode. It also has a built-in battery, which I found surprised. While I'll be plugging the device in all the time, it's nice to have the freedom to move it around whenever I want. When you plug in the AC adapter, it starts charging but won't turn on. Press the power button to turn on. The instructions are great, the assembly instructions are very easy to follow. It includes detailed instructions on how to pair, switch modes, and even how to set the mode if you want to keep it connected all the time (referred to as standby in the manual). The sound quality is good to my ears, I didn't hear any difference compared to my TV's aux out when connected to B&O speakers, although I have to admit my ears aren't as sensitive as audiophiles'. Overall I think it's a great product, the aux cable and optical cable are 6ft long, I didn't measure the micro USB charging cable but it's also quite long. The only thing that I think could be improved is the addition of a volume control, there is a drop in volume compared to a direct aux connection.
