Why this model
-
Open-ear bone conduction — a 17 × 10 mm racetrack transducer rests on the cheekbone and leaves the ear canal open, so traffic, teammates and coaching stay audible
-
Coupled dual-driver transducer — a dynamic driver and a bone-conduction element are driven as one unit for full-band, directional output with noticeably less sound leakage
-
Bluetooth 5.2 on an AC7006F4 platform — HSP / HFP / A2DP / AVRCP profiles and up to 10 m of stable range, auto power-on pairing
