Sennheiser HDB 630 Wireless Noise Cancelling Headphones

Description

Sennheiser HDB 630 Wireless Headphones

The Sennheiser HDB 630 is a premium closed-back wireless headphone designed for listeners who want genuine audiophile sound without giving up the convenience of Bluetooth, active noise cancellation and long battery life.

Using Sennheiser’s own 42mm transducer, the HDB 630 is tuned for a neutral, detailed presentation with controlled bass, natural midrange and an open, spacious soundstage. With support for high-resolution audio up to 24-bit/96kHz, adaptive noise cancellation and an included BTD 700 USB-C Bluetooth dongle, it is designed to deliver high-quality listening at home, at work or on the move.

Sennheiser 42mm Transducer

At the heart of the HDB 630 is a 42mm dynamic transducer developed in-house by Sennheiser. The acoustic system has been carefully tuned to deliver fast, controlled bass, lifelike vocals and finely resolved treble without exaggerating any particular part of the frequency range.

Despite its closed-back construction, the HDB 630 is designed to create a broad and natural soundstage, making it equally suitable for relaxed listening and more critical sessions.

High-Resolution Wireless Audio

The HDB 630 supports aptX Adaptive, aptX HD, aptX, AAC and SBC Bluetooth codecs. For compatible devices, the included BTD 700 Bluetooth USB-C dongle provides access to high-resolution wireless playback, helping phones, tablets and computers deliver a higher-quality Bluetooth signal to the headphones.

Up to 24-bit/96kHz Listening

For the highest possible quality, the HDB 630 can also be connected directly via USB-C. USB playback supports audio up to 24-bit/96kHz, while the included analogue cable allows conventional wired listening from a standard 3.5mm headphone output.

This gives the HDB 630 useful flexibility between wireless convenience and lossless wired listening.

Adaptive Noise Cancellation

Powerful adaptive active noise cancellation helps reduce unwanted background noise while preserving the clarity and balance of the music. The system continually adjusts to surrounding conditions, making the HDB 630 particularly useful for travel, commuting and busy working environments. A transparency mode is also available when you need to remain aware of your surroundings.

Advanced Parametric EQ

The HDB 630 offers much more control over sound than a conventional bass and treble adjustment. Through the Sennheiser Smart Control Plus app, listeners can use an advanced parametric equaliser to fine-tune the frequency response to suit individual tastes, recordings or listening environments.

This makes it possible to make precise tonal adjustments while still retaining the fundamentally neutral character of the headphones.

Crossfeed for More Natural Stereo

A built-in crossfeed function is designed to make some stereo recordings sound more natural through headphones. Older recordings in particular can feature instruments positioned almost entirely in one channel. Crossfeed subtly blends information between the left and right channels, creating a presentation closer to listening through conventional stereo loudspeakers.

Up to 60 Hours Battery Life

The HDB 630 offers an impressive up to 60 hours of battery operation, making it well suited to long journeys, extended work sessions and everyday listening without frequent charging. Its combination of long battery life and active noise cancellation makes it particularly practical for listeners who regularly use headphones away from home.

Designed for Long Listening Sessions

Comfort has been given considerable attention. The generously sized over-ear earcups use soft synthetic leatherette pads, while the headband is wrapped in refined Japanese leatherette.

At 311g, the HDB 630 remains relatively lightweight for a full-size premium wireless headphone, while carefully controlled clamping pressure helps maintain comfort during longer listening sessions.

Closed-Back Design

The closed-back construction helps reduce sound leakage while also providing useful passive isolation from external noise. Combined with adaptive ANC, this makes the HDB 630 suitable for listening in shared spaces, offices, trains and aircraft without sacrificing the detailed presentation expected from a serious hi-fi headphone.
