Sennheiser HDB 630 Closed-Back Active Noise Cancelling Bluetooth Headphones

High-res wireless headphones that go everywhere

Meet the headphone that finally delivers true high-performance sound without the wire. The Sennheiser HDB 630 takes the brand’s 80-year acoustic heritage and packs it into a sleek, versatile wireless package, giving you studio-level music fidelity whether you’re at home, in a café, or 30,000 feet above the ground.

Why It Matters

If you’ve been waiting for a wireless headphone that actually sounds like high-end gear, this is it. Tuned with Sennheiser’s custom 42 mm transducers — hand-built at their Tullamore facility in Ireland — the HDB 630 delivers a balanced, neutral sound that unpacks every nuance from your favorite recordings. Midrange clarity, tight yet extended bass, and transparent highs come together like you’re in the control room, not just listening through Bluetooth.

Audiophile-Grade Sound

• Custom tuning and advanced EQ (including parametric and Crossfeed) in the Smart Control Plus app let you sculpt your sound like a pro.

Comfortable & Ready to Go

Long sessions are effortless thanks to a lightweight design, plush Japanese Protein Leatherette headband and ear pads, and relaxed clamping force — the kind of comfort that invites you to forget you’re even wearing them.
