And with IPX4-rated splash and sweat resistance, your wireless earbuds keep performing, rain or shine, no matter what you're up to.

Feel your tunes, not the earbuds.

Meet your perfect fit

With the comfort of barely-there earbuds, ACCENTUM Open earbuds are the perfect choice if you find ear canal designs too insulating or too large to fit securely. Plus, the open-ear stem design means no uncomfortable pressure or ear canal invasions. Your lightweight, breathable earbuds stay in place and feel weightless all day long, with a handy stem that makes them easy to pop in and out whenever you like.

Effortless use, no manual needed

Keep it simple, keep it smart

Life’s complicated enough already — ACCENTUM Open earbuds keep things simple. Multipoint connectivity lets you seamlessly switch between two devices, so you’re always in sync, whether it’s videos, calls, or music. No need to fumble with settings. Smart touch controls make everything intuitive — no manual required. Smart Pause stops playback the moment you remove an earbud, and the dual beamforming microphones, combined with AI-based noise reduction, ensure crystal-clear calls. Just connect and go. Now that's music to your ears.
