Review on IMDEN Bluetooth 5.0 FM Transmitter for Car: Stream Music, Hands-Free Calls, 2 USB Ports Charger by Brian Malith

Oops, muffled sound quality, like hearing your speakers under a pile of blankets. I have followed all instructions including additional instructions on this product's Amazon page and the sound quality has not improved. My work is in audio and video and I've never had good experience with wireless transmitters like this product but thought I'd give this one a try. I've tried plugging the device into the outlet in the front of the car as well as the power outlet in the back just in case the signal from the device is weak. The results were the same in both places: poor, muffled sound quality. The only reason I'm leaving it on is because I'll be using it for a USB charging port and a voltmeter will come in handy. but I would not recommend this or any other high frequency bluetooth audio transmitter. There's just no decent sound quality. I am planning to replace the factory radio in my 14 year old 4Runner with a new cheap bluetooth radio. This is the best solution, and decent Bluetooth radios can be found for less than $100.
