Why JS660
Made for real days.
Long days, noisy streets, quick exits, constant switching — every part of the JS660 is built around the way you actually listen.
Rich. Deep. Clear.
A 13.4mm driver delivers Hi-Fi detail and punchy bass, while dual mics keep your calls crisp.

/ NOISE CANCELLATION
Your voice, without the street.
ENC listens to the world around you and filters it out in real time. A main mic captures your voice, a secondary mic cancels up to 40 dB of background noise — so calls stay crisp on a train, in a café or by the road.

- Up to 40dB suppression
- Clear calls in noisy scenes
