If your car stereo doesn't support playing music from flash drives or doesn't have Hands Free function, this compact Bluetooth car transmitter from JOYROOM will definitely be useful. The transmitter works from the cigarette lighter. It transmits music via Bluetooth version 5.3, which differs from previous models with improved performance, more reliable connection and extended data transmission range. The transmitter also features two fast charging ports with a total of 48W of power, an AUX audio input and a laptop charging port. So now you can charge two gadgets at once at maximum speed. In addition, additional microphones and noise-canceling technology will make hands-free communication comfortable. And of course, we note the excellent sound of music due to the amplification of low frequencies. So this transmitter will be a good companion on the road.
