Review on Wireless Bluetooth Adapter with LCD Display | Bluetooth Transmitter Receiver, Low Latency 5.0 Audio Adapter | Dual Link Optical RCA AUX for Headphones, TV, PC, Laptop, Speaker by Justin Ellingson

Assembly was very easy. but more information is needed in the manual. Also, I've found that if you use this to pair up to 2 headphones together, yes, they pair very quickly and don't fall out. I found that the Bluetooth transceiver needs to be disabled first. Then turn off your headphones when you're not using them and do it the other way around. You need to reconnect one of the headphones. That minor issue aside, this is an excellent device for transferring tunes.
