SennheiserAccentum Wireless Open-Ear Earbuds

About

The Sennheiser Accentum Open are true-wireless earbuds with an open-ear / semi-open design, meaning they don’t fully seal in your ears. This allows you to remain more aware of your surroundings (ambient sound) while still enjoying music or calls. They are engineered to balance audio quality with comfort and usability, featuring lightweight ergonomics, multipoint connectivity, and an extended battery life courtesy of their charging case.
