Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas ★★★★★

The 18-hour battery claim held up through a full week of commutes and gym sessions, and USB-C charging tops it back up fast. The clip design keeps them snug on my ears without crushing them, even during a long run.

Andrew ★★★★★

The in-line microphone and remote make taking calls a breeze without fumbling for my phone. Battery life has easily gotten me through two full workdays on a single charge.

Mia Z. ★★★★★

The clip-on design is perfect for my workouts—they stay put even when I'm running errands. USB-C charging is super convenient, and I get about 18 hours of use before needing a recharge. The in-line mic makes taking calls on the go a breeze.
