Many listings cite sweat resistance; some in‑ear models and their charging cases are rated IP54 for dust, sweat, and water resistance. At least one wired model is shown with no water‑resistance rating.
Some in‑ear models list multiple ear tip sizes (for example, five sizes or four silicone tip pairs XS–L). Other listings describe redesigned contours and case/fit changes intended to improve comfort and stability.
Listings describe touch or press controls and physical controls (including a rotating crown on some over‑ear models for volume and track control), integrated voice‑assistant interactions, automatic pairing/switching, and hands‑free call and mute options.
