For active listeners who need long battery life

Suits runners, gym users and commuters wanting IPX7 waterproof protection and a secure in-ear fit with touch controls. Not for buyers who require active noise cancellation, multi-point Bluetooth pairing or a USB-C fast-charge specification.

48-hour total playtime with IPX7 waterproof rating

The charging case supplies enough reserve power for 48 hours of listening, while each earbud weighs 4 grams and resists sweat and rain to IPX7. A 1.5 hour charge restores the case and the Bluetooth 5.3 link remains stable up to 33 feet.
