Sennheiser HDB 630 Closed Back ANC Over-Ear Headphones

Audiophile sound, cut loose

The Sennheiser HDB 630 delivers the freedom of wireless listening with uncompromising audiophile performance. Combining precision engineering, advanced acoustic tuning and studio-grade components, these closed-back over-ear headphones offer remarkable detail, balance and depth. Designed for discerning listeners, they bring the clarity of high-end wired sound to a truly portable form.

Flawless sound, anywhere

At the heart of the HDB 630 are Sennheiser’s SYS38 42 mm dynamic transducers, engineered for a neutral, transparent sound signature. Expect articulate, accurate bass, refined midrange tones, and smooth treble that creates a wide, airy soundstage. Each pair is carefully tuned by Sennheiser’s acoustic team to capture every nuance of your music with lifelike realism.

High-resolution wireless freedom

The HDB 630 supports Bluetooth 5.2 with aptX Adaptive, aptX HD, AAC, and SBC codecs for exceptional high-resolution playback. When connected via USB-C, it delivers 24-bit / 96 kHz audio, ensuring your music retains every detail from studio to ear. Pair it with the Sennheiser BTD 700 transmitter for the purest wireless experience possible.

Intelligent listening control

Tailor your sound precisely with the advanced parametric equaliser available through the Sennheiser Smart Control Plus app. This powerful tool allows you to define frequency bands, bandwidth, and filters for a truly personalised sound signature. The integrated Crossfeed function recreates the natural stereo effect of loudspeakers, ideal for classic and vintage recordings.

Active Noise Cancellation and comfort

The Hybrid Adaptive ANC system reduces external distractions without compromising tonal accuracy, so you can focus on what matters most—your music. The closed-back design, cushioned earcups, and protein leatherette headband ensure long-term comfort during extended listening sessions, whether travelling, working, or relaxing at home.

Long-lasting power

With up to 60 hours of playback on a single charge, the HDB 630 offers exceptional endurance. A 10-minute quick charge provides up to seven hours of listening time. The built-in 700 mAh lithium-ion battery has been tested for over 500 charge cycles, delivering reliability that lasts.

Designed for everyday excellence

Precision-crafted with a new earcup finish and robust build quality, the HDB 630 folds flat for easy storage in its premium carry case. Every detail reflects Sennheiser’s commitment to engineering excellence and long-term durability. A two-year warranty provides additional peace of mind.
