I connected this product to two 3 inch full range speakers in the cabinet. I used a standard 5 volt cell phone charger to provide power. The result was very responsive. Bluetooth system. I use my mobile phone to connect to the device and play music through it. The sound is good and the volume slider allows me to adjust the volume, especially when my phone is at maximum volume. An inexpensive way to build your own Wi-Fi speaker system.
