Sennheiser HD 630 Wireless Over-Ear Headphones - Black

The Sennheiser HD 630 Wireless is Sennheiser's flagship closed-back over-ear headphone, engineered for the serious audiophile who refuses to compromise between studio-grade sound quality and wireless freedom. Combining Bluetooth 5.2 connectivity, aptX Adaptive support for up to 96kHz resolution, and a USB-C connection for lossless audio, the HD 630 Wireless delivers a listening experience that rivals wired reference headphones — without the tether.

Audio Performance

At the heart of the HD 630 Wireless is an electrodynamic (moving coil) transducer engineered to reproduce the full frequency spectrum with exceptional accuracy. Frequency response extends from 6 Hz to 40 kHz — capturing sub-bass rumble and ultra-high-frequency detail that most headphones simply cannot reproduce. With aptX Adaptive Bluetooth or USB-C, you're listening at up to 24-bit / 96kHz resolution — true hi-res audio, wirelessly.

• Frequency Response: 6 Hz – 40 kHz (USB-C / aptX Adaptive); 6 Hz – 22 kHz (standard Bluetooth)
• Resolution: Up to 24-bit / 96kHz (USB-C, Line-In, or BTD 700 Dongle)
• THD: <0.2% at 1 kHz / 100 dB SPL — vanishingly low distortion
• SPL: 105 dB (1 kHz / 0 dBFS)
• Nominal Impedance: 480 Ohm (active mode)
• Acoustic Design: Closed-back — excellent passive isolation, ideal for focused listening sessions

Wireless Connectivity

The HD 630 Wireless supports Bluetooth 5.2 with a comprehensive codec suite, ensuring compatibility with virtually every source device while prioritising quality wherever possible.

• Bluetooth Version: 5.2
• Supported Codecs: aptX Adaptive, aptX HD, aptX, AAC, SBC
• USB-C: For wired hi-res audio and charging
• BTD 700 Compatible: Use the optional BTD 700 Bluetooth USB-C Dongle with computers for aptX Adaptive over Bluetooth

Build & Comfort

Designed for extended listening sessions, the HD 630 Wireless features premium leatherette over-ear pads, a detachable 1.2m audio cable with 3.5mm plug (right-side connection), and a refined closed-back housing. Weighing just 311g without the cable, it sits comfortably for long-form listening without fatigue.

When To Use

The HD 630 Wireless is suited to critical listening at home, studio monitoring, audiophile music sessions, and extended work-from-home use where audio quality matters. The closed-back design provides natural sound isolation — ideal for focused environments or shared spaces where you need to stay in your own sonic world.

Who Is It For?

Designed for the discerning listener — whether you're an audio engineer, a hi-fi enthusiast stepping into wireless, or simply someone who refuses to settle for average sound. If you understand what aptX Adaptive means and why 96kHz matters, the HD 630 Wireless was built for you.
