Listings mention several non‑audio extras: Live Translation, built‑in heart‑rate sensing for workouts, a Hearing Test and hearing‑aid/hearing‑protection features, plus personalized listening tools within compatible device ecosystems.
Common noise‑control features include Active Noise Cancellation (ANC) and a Transparency mode that lets ambient sound in. Several listings also mention adaptive noise control (branded as Adaptive Audio or Adaptive EQ) that blends ANC and transparency.
Most product details list built‑in microphones. Several entries highlight call‑quality features such as dual or custom‑designed microphones, noise‑learning algorithms, and generally high call performance.
