Reliable wireless streaming – thanks to Bluetooth 5.4
Bluetooth 5.4 provides a more stable link and improved throughput compared with older Bluetooth generations, reducing dropouts during music playback. The protocol also helps maintain consistent audio quality across short interruptions.
Stable connections keep playlists playing smoothly on daily commutes and longer drives. Phone calls and media playback stay linked even when switching between stops and tunnels.
Clear hands-free calls – with active noise cancellation and built-in mic
Active noise cancellation reduces background noise before transmission, while the integrated microphone captures voice for call clarity. These elements work together to improve vocal intelligibility in noisy cabin environments.
Conversations come through with fewer distractions, making phone calls usable without picking up the phone. Practical for business calls or hands-free navigation directions while driving.
Easy control and simultaneous pairing – thanks to multi-function buttons and dual-connection
Physical multi-function buttons enable call control, track skipping and volume adjustment locally, while dual-connection allows two Bluetooth devices to remain paired and ready for audio or calls. USB power is used for operation while the 3.5mm jack handles audio output.
Quick one-hand control keeps attention on the road and lets passengers stream from a second phone without re-pairing. Setup requires only plugging into an AUX jack and supplying USB power.
