Bluetooth 4 1 Transmitter and Receiver ARCHEER 2 in 1 3 5mm Wireless Audio Adapter

This device can be used as a Bluetooth Transmitter or Receiver. That means you can plug it into your home stereo and receive the transmission from your tablet or phone. You can also attach it to an old MP3 player that doesn't have Bluetooth and transmit it to some BT speakers. I've hooked mine up to my home stereo and I play music from my tablet to the surround speakers. It's so nice to have good sound again. This thing is really tiny. It does all it needs to do and fits in your pocket when you're done. I have no relation to the seller. I just like to bring good products to my subscribers when I can. I got mine here: https://www.amazon.com/dp/B079N89SYD
