The Q39 Car MP3 Player is a budget-friendly in-car Bluetooth FM transmitter designed to upgrade your car’s audio system and add modern wireless features to older vehicles.
It plugs directly into the 12V cigarette lighter socket and connects to your car stereo through an FM frequency. Once paired with your phone via Bluetooth, it lets you stream music, make hands-free calls, and charge your devices while driving.
This model is commonly seen as a generic “white-label” device, meaning different brands may sell the same Q39 design with slight variations in features and branding.
Key Features: • Bluetooth wireless music streaming (usually Bluetooth 4.0/5.0 depending on version) • FM transmitter for playing audio through car radio • USB port + TF/SD card support for MP3 playback • Dual USB charging (varies by version) • Built-in microphone for hands-free calling • LED display showing FM frequency and track info • Supports 12V–24V vehicles • Plug & play installation
The Q39 is ideal for users who want a simple and affordable way to add Bluetooth music and charging features to older cars without built-in infotainment systems. It focuses more on practicality than premium sound quality or advanced smart features.
Overall, it’s a basic but useful all-in-one car audio adapter for everyday use.
