I still have some serious hi-fi that's barely starting these days. When this happens it usually means I'm using a 3.5mm phono stage to play music from my phone. The problem is that my "cell phone" is now immobilized at the end of the cable. With this gadget, I keep my phone with me while the music streams to my 100 watt RMS speakers via Bluetooth. It's simple and works well. Because it contains a battery, it doesn't need to stay connected to a USB power source, although I intend to. The instruction manual is a bit crooked and doesn't mention the sound mode button. Luckily, the Revain list has an illustration to match.
