Product Information
Satisfying the needs of music purists on the move, the Sennheiser HDB 630 brings wireless Hi-Res Audio to noise-cancelling headphones.
Audiophile sound, in wireless freedom
Tuned in-house for pure sound and stunning detail, these audiophile headphones use minimal digital processing for exceptional clarity. Supplied with the BTD 700 Hi-Res USB-C dongle, they deliver 24-bit / 96kHz Hi-Res sound via both wired USB-C and wireless Bluetooth. Parametric EQ lets you optimise the bass, vocals or other frequencies to suit your tastes. Adaptive ANC with Transparency Mode allows you to listen to music in an oasis of calm.
Signature Sennheiser sound
Tuned for a neutral sound, with smooth bass and rich, intimate vocals, the Sennheiser HDB 630 headphones are true to the signature Sennheiser sound. With a newly developed acoustic mesh and optimised cavity, they produce a highly refined sound that’s smooth and consistent for listening in comfort, hour after hour.
Hi-Res music, wired or wireless
Supplied with a BTD 700 BT dongle, these Sennheiser headphones deliver wireless Hi-Res audio at up to 24-bit/96kHz sampling rates. The USB-C dongle is compatible with around 80% of smartphones, plus most tablets and laptops, making wireless Hi-Res sound a reality for most. The headphones are also supplied with a USB-C 1.2m cable that facilitates Hi-Res Audio via a wired connection.
Advanced audio control
Introducing Parametric EQ, the HDB 630’s offer expert-level tuning for precise adjustment to best suit your tastes. The headphones also feature crossfeed to reduce the extreme channel separation that can be present on some early stereo recordings.
Adaptive Noise Cancellation
Sennheiser’s latest Adaptive Noise Cancellation (ANC) system makes these headphones perfect for music on the move. Once activated, ANC monitors ambient sound levels and then blocks out background noise. This optimal noise cancellation system makes it much easier to hear your music when traveling or at work in a busy office.
Transparency Mode for situational awareness
Ideal for when you’re at a station or airport and awaiting an important announcement, Transparency Mode lets you hear more, keeping you better in touch with the outside world. This mode is also recommended for when walking or running outside.
Long-lasting battery life
With an impressive battery life of up to 60 hours, the HDB 630 headphones provide days of listening. Even more impressively, the 60 hours playback time is available with Bluetooth and ANC functions switched on and the headphones playing at around half volume. A full recharge takes around two hours, with seven hours playback available after just ten minutes charging.
Supreme comfort
With a frame that’s both lightweight yet strong, and deeply cushioned earpads, the HDB 630 headphones provide fatigue-free comfort to match the sound. The clamping force is optimised for a secure yet comfortable fit that doesn’t press down too hard.
Sustainable build
Sennheiser has an enviable reputation for durability and sustainability, with many parts still available for long-running models. With the HDB 630, the high quality, sustainable leatherette headband is sourced from Japan. Spare earpads are also available, extending the headphones’ lifespan.
