Review on 🚗 Upgraded Version Bluetooth 5.0 Car Adapter with FM Transmitter by NECESPOW - MP3 Player, Wireless Radio Receiver Car Kit with 39W USB-C PD+QC3.0 Hands-Free Car Charger, AUX/TF Card/U-Disk Support by Steve French

I've waited two weeks to write this review after using it for a while. I mainly use this to connect my phone to my car stereo so I can listen to music on my phone while driving. The Bluetooth connection between the phone and the transmitter is very simple and reliable. The sound transmitted to the car radio is clear as long as the selected FM channel is free in your area. I live in a large metropolitan area where it's not easy to find a good 30 channel station to play music from your phone through your car FM radio as the FM channels are so crowded. This outperforms all similar transmitters I have previously purchased and used. If the phone is not playing music when connected to the car stereo, you can still hear a normal hissing sound in the background. When a real signal is being played on the phone (e.g. music or a phone call), the sound quality reproduced through the car stereo is good and background noise is almost completely masked and barely audible. with a dedicated USB charging port and another USB input/output port. Both can be used to charge USB devices at the same time, which means two mobile phones can be charged at the same time through this FM transmitter while enjoying music. All in all a good and useful FM transmitter for those who need one.
