Rvelon FM Transmitter Car MT04B – Bluetooth 5.3 with Fast Charging and 3D Surround Sound

A car FM transmitter that lets you stream music and take calls wirelessly via your car's stereo system — and also quickly charges your devices with both USB-C Power Delivery and Quick Charge 3.0. The MT04B combines sound quality, charging function, and a distinctive appearance in one unit.

Bluetooth 5.3 — stable and fast connection

Bluetooth 5.3 provides a stable and energy-efficient connection with a range of up to 8 meters. Thanks to the new version, the device also connects faster and maintains a stable connection even in environments with a lot of wireless traffic.

3D surround sound — more than ordinary FM sound

The built-in music processing algorithm delivers 3D surround sound that fills the entire car cabin with a complete sound range. This provides a noticeably more engaging listening experience compared to a regular FM transmitter.

Adjustable bass and treble controls — customize the sound to your taste

The distinctive metal rollers allow you to freely adjust bass and treble according to your music style and preference. Thanks to the physical controls, you can also easily adjust the sound while driving without having to navigate an app or menu.

Automatic hands-free for incoming calls

For incoming phone calls, the device automatically switches from music mode to speaker mode, meaning you answer calls hands-free without having to press anything. Thanks to this, you also keep your eyes on the road.

USB-C PD 20W and QC3.0 — fast charging for two devices

The two USB ports charge one device via USB-C with up to 20W Power Delivery and another via USB-A with Quick Charge 3.0 — meaning you fast charge both passengers' phones while driving without compromising charging speed.

RGB lighting and voltage indicator

RGB LED lighting provides an impressive appearance in the car's interior and creates a more pleasant atmosphere while driving. In addition, the device automatically detects the car battery's voltage at startup, giving you a quick indication of the battery's status.
