Sennheiser has introduced the HDB 630 over-ear headphones, specifically crafted for those who love high-resolution music.
Design and Comfort
The HDB 630 features 42 mm drivers and boasts ear cushions made from Japanese protein leatherette, all structured within a frame inspired by the company’s Momentum 4 headphones.
Sound Customization and Features
Using the Smart Control Plus app, users can adjust sound playback with a parametric equalizer, fine-tune left and right speaker blending, and even share their settings with others. The adaptive active noise cancellation effectively blocks out external sounds, while a transparency mode is available for conversations.
Connectivity and Battery Life
The HDB 630 connects to audio devices via wired 3.5 mm and USB-C cables, in addition to wireless Bluetooth 5.2. It comes with a BDT 700 USB Type-C transmitter dongle that supports the aptX Adaptive audio codec, making it compatible with phones lacking this feature. According to the company, these headphones offer a remarkable 60-hour battery life and can provide an additional 7 hours of playtime with just ten minutes of quick charging.
Audio Quality and Pricing
The wireless audio codec allows for dynamic modifications to sound latency and quality, achieving latencies as low as 80 msec and audio fidelity up to 24-bit, 96 kHz at 420 kbps. However, there has been no confirmation on whether the headphones support the LDAC codec, which is favored by modern Android devices.
The Sennheiser HDB 630 headphones are priced at $499.95/€499.90. They will be open for pre-order starting October 8, with shipping expected to begin on October 21, 2025. Interested buyers can find them on the Sennheiser store on Amazon.
