Review on 🔌 UGREEN Bluetooth Aux Adapter 3.5mm Audio Receiver with Built-in Microphone - USB 2.0 Car Receiver for Handsfree Calling, Car Speaker and Home Audio by Ryan Whatley

This elegantly designed mini receiver replaces a 3 year old USB/Audio (optional) Bluetooth 4.1 adapter cable. In comparison, this device is about 1/3 the size, easily plugs in, and connects instantly when I turn on my machine. The thin, twisted cable does not get in the way and is almost invisible. I haven't tried the microphone for calls yet. A small blue LED indicates operation. This is pretty amazing technology!
