Open-Ear Design for Situational Awareness

These earbuds use an open-ear architecture that leaves the ear canal unobstructed while delivering private audio. Each bud weighs 6 g and hooks gently behind the ear for a secure fit. Bluetooth connectivity provides a 30 feet wireless range. The IPX4 rating protects against splashes and moisture.

Suited for Commuters and Outdoor Users

Listeners who want music without losing awareness of traffic, announcements or conversations will benefit. The 7.5 hour battery extends to 19.5 hours with the case, or 4.5 hours when spatial audio is active. Buyers who require active noise cancellation or sealed isolation for loud environments should consider other styles.

Case and Cable Extend Daily Use

The supplied charging case stores 19.5 hours of additional play time and recharges fully in 1 hour via USB-C. A USB-C cable is included for power delivery. Simple button controls on the buds handle playback, calls and switching between stereo and immersive modes without needing a phone app.
