Review on 🚗 CICMOD Car Audio Cassette Adapter Tape BT4.0 Aux Receiver for iPhone iPod Android Samsung Black: Enhanced Sound Quality and Bluetooth Connectivity by Matt Abba

I really hate it when a salesperson says the wrong thing and tries to mislead customers. It's not stereo. Tested with YouTube audio source test. This is a mono output. During the test, the left and right audio sounds the same, then the middle audio sounds louder (that means the BT transmitter outputs stereo but the cassette head does not. Finally, if the channels are out of phase during the test, there is no audio, which means that the sound comes out in mono.Very disappointed.
