Review on Comsoon [2021 Upgraded] Dual Connect Bluetooth AUX Adapter: Noise Cancelling Music Receiver for Car/Home Stereo/Headphones, Hands-Free Calls, 16H Battery Life - Black+Gray by Vladimir Castillo

Note: It must be used with your phone. I bought it to use with my bluetooth headphones so I can listen to music on my home stereo while roaming around the house freely. nope! It's more for streaming music from your phone to another device, so it's more of a transmitter than a receiver. I was originally attracted to this product because of the advertised battery life. I have another Bluetooth adapter that works as I wanted, but the one I'm using needs to be charged after 3.5 hours of use. Warning: Returning this item is also problematic. I have to print the label (I don't have a printer) and mail it in person even though it was sent to me via Revain Prime.
