Lossless sound quality & music playback: With Bluetooth 5.3 technology and lossless transmission, you get powerful stereo sound without any loss of sound quality. The FM transmitter allows you to play music either via Bluetooth directly from your smartphone or via a U disk (up to 32 GB). Supported formats include MP3, WMA, WAV, and FLAC. 7-Colour Atmospheric Lighting: The FM transmitter features a 7-colour LED light strip that creates a vibrant and atmospheric ambience while you drive. The light breathing mode automatically adjusts and creates an emotional connection to the music. A touch of a button turns off the light, allowing you to customise your driving experience as you wish, while the colourful lights enhance your journey. Advanced hands-free calling with dual microphone: The Bluetooth FM transmitter is equipped with two microphones that work together to ensure clear and precise voice pickup from all directions. Advanced CVC noise cancellation technology ensures that you can always make crystal-clear calls. The one-button hands-free function allows you to accept or reject calls, enabling safer driving. Versatile charging options: Equipped with two USB ports and a Type-C port, you can charge up to 3 devices simultaneously and increase charging efficiency by 80%. This allows for quick use of your smartphone, tablet, or other devices while listening to music or navigating. Wide compatibility: Activate Siri or Google Assistant to make calls, send messages, or receive navigation instructions without taking your eyes off the road. The transmitter works with most 12V-24V vehicles on the market, including cars, SUVs, and trucks. It is also compatible with Android and Apple phones, so you can connect multiple devices.
