This compact car FM transmitter from SONRU combines Bluetooth 5.3 audio streaming with a dual fast-charging system, making it easy to play music and charge devices on the road. It works through FM transmission, TF card playback or the 3.5 mm AUX output, so you can switch between sources depending on availability and preference.

Key Points

The unit offers seamless hands-free calling thanks to a built-in microphone and one-button call control, which switches automatically from music to phone calls. A small LED digit display shows vehicle voltage and the selected FM frequency, while seven colourful ambient light options help set the mood inside the cabin. The transmitter can be mounted using the included air vent clip or the sticky dashboard seat, and the supplied 1.1 m cable increases placement flexibility inside the vehicle. 🎵

Place the transmitter where the microphone has a clear path to the driver for better call clarity. If you plan to use the TF card, format it and load files in widely supported formats before use to ensure compatibility. Note that FM transmission quality depends on local radio conditions and may vary between locations. 🎧
