Sennheiser Accentum Wireless Headband, White

Freedom to listen longer: signature Sennheiser sound, minus the noise

Lose the battery anxiety, the device-juggling, and the “will it isolate enough?” second-guessing. Accentum Wireless delivers up to 50 hours of playtime with hybrid active noise cancellation, multipoint Bluetooth for effortless switching, and the kind of balanced, bass‑confident tuning Sennheiser fans expect—all in a light, fold‑flat design that disappears on your head. In white with sandstone accents, it sounds refined and looks it too.

Why Audiophiles Choose This Product

• Sound you can trust: 37 mm Sennheiser transducers tuned for engaging, bass‑capable sound with clear mids and highs. Out of the box it leans a touch warm; the Smart Control app’s 5‑band EQ lets you dial in your preferred signature. Reviewers note the bass emphasis and easy EQ tailoring.
• Engineered for real life: Hybrid ANC reduces outside distractions and Transparency mode brings the world back in with a tap. A wind‑reduction mode keeps calls intelligible when the weather turns.
• Practical comfort: At just 222 g with plush padding and a fold‑flat silhouette, Accentum is built for marathon sessions and compact packing.
• Works with your devices: Bluetooth 5.2 with multipoint pairs to two devices at once. Codecs include SBC and AAC for broad compatibility and aptX/aptX HD for high‑quality listening on many Android devices. USB‑C “wired” audio lets you listen (and take calls) from class‑compliant USB sources while charging. Note: Apple devices use AAC rather than aptX.
• Battery that sets you free: Up to 50 hours on a charge; 10 minutes of fast charge yields up to 5 hours of playback—perfect for the dash out the door.

Notes for discerning buyers:

• For iPhone and Mac users, Accentum uses AAC; aptX/aptX HD benefits are realized with many Android/Windows sources that support those codecs.
• ANC is effective for everyday distractions; frequent flyers facing deep engine rumble may find premium ANC models more isolating.
