AAC and SBC codec support combines with a built-in isolation module to reduce current noise. Clear voice pickup helps with hands-free calling while keeping music quality high.
Reliable, stable connection – with Bluetooth 5.4
Bluetooth 5.4 provides a stronger signal and more stable pairing than earlier versions, reducing dropouts over short ranges. Dual-connection logic allows two devices to remain connected and switch audio sources without repeated pairing.
Consistent streaming for in-car journeys and home setups improves playback reliability. Quick swaps between phone and passenger devices prevent missed calls and interruptions.
Clear music and calls – thanks to AAC/SBC codecs and isolation module

Expect noticeably clearer vocals and reduced hiss compared with FM transmitters or unfiltered aux feeds. Hands-free conversations sound cleaner, helping drivers keep focus on the road.
Long runtime and usable while charging – with 15-hour battery and pass-through use
A 15-hour playback capacity follows a roughly two-hour charge cycle, and the adapter supports operation while connected to external power. Battery management allows continued streaming during long trips without interruption.
