Stable, low-latency streaming – thanks to Bluetooth 6.0 chip
Bluetooth 6.0 delivers improved signal handling and lower transmission delay compared with older Bluetooth versions, supporting longer-distance, more reliable links. Updated pairing protocols reduce dropouts during everyday use.
Music and Sat Nav directions stay in sync with minimal lag and fewer connection interruptions, making the adapter dependable on journeys.
Hands-free calling and easy multitasking – with built-in microphone and dual connection
An integrated microphone handles incoming calls and the adapter supports two simultaneous Bluetooth connections, allowing both driver and passenger phones to remain paired. Switching between devices is possible without going through full re-pairing.
Accept calls through the car or home speakers and switch between two phones quickly, useful for family cars or shared home systems.
Always ready, no charging fuss – with USB power and auto-on behaviour
USB-powered design draws energy from the vehicle or USB port so there is no internal battery to charge, and the adapter connects automatically when ignition power is available. Power removal causes the connection to drop when the vehicle is turned off.
Plug-and-play operation means audio is available as soon as the car starts, avoiding separate recharging or manual power management.
