Short Answer: If you want one pair that does both: everyday wireless ANC and true wired hi-res up to 24-bit/96kHz, the Sennheiser HDB 630 fits. It ships with a USB-C transmitter for aptX Adaptive, runs up to 60 hours with ANC, and keeps a familiar Momentum-style fit. Budget $500 and consider rivals if you need LDAC.
What the Sennheiser HDB 630 Is (and isn’t)
This is Sennheiser’s new premium wireless noise-canceling headphone with a twist: serious wired mode over USB-C or 3.5 mm, supporting up to 24-bit/96kHz. It inherits the Momentum 4 chassis feel but adds a new acoustic system and parametric EQ for finer tuning. It’s not a studio headset and it doesn’t promise Bluetooth lossless.
At-a-Glance Specs & Terms
- Drivers: 42 mm dynamic, tuned for clarity and midrange detail.
- Wireless: Bluetooth 5.2 with aptX Adaptive; USB-C transmitter included for phones/tablets that lack it.
- Wired: USB-C or 3.5 mm, up to 24-bit/96kHz.
- ANC: Adaptive noise canceling + transparency.
- Battery: Up to 60 hours with ANC; ~7 hours from a 10-minute top-up.
- Extras: Parametric EQ, Crossfade spatial blend, QR-shareable presets; airline adapter.
Terms you’ll see:
- aptX Adaptive: a flexible Bluetooth codec that adjusts bitrate for stability and quality; not the same as aptX Lossless.
- 24-bit/96kHz: wired digital resolution ceiling here; helpful if you already use hi-res libraries.
- Parametric EQ: lets you pick frequency, bandwidth (Q), and gain—more precise than a simple bass/treble slider.
Price Brackets & What You Get
- $499.95 MSRP (USA): headphone, case, USB-C transmitter, USB-C cable, 3.5 mm cable, airline adapter.
- India pricing: expect regional variance; check local retailers and taxes. Global shipping starts October 21, 2025.
Best Configurations by Use Case
- Everyday travel + meetings: Use Bluetooth with ANC; enable transparency for quick chats. Preset EQ: slight mid lift for voices.
- Hi-res listening at desk: Go wired via USB-C to your laptop/phone for 24-bit/96kHz.
- Phones without aptX Adaptive: Plug the included USB-C transmitter for higher-quality wireless vs SBC/AAC on many devices.
- Gaming on handhelds/switches with USB-C: Use the transmitter or wired 3.5 mm to avoid latency spikes.
Alternatives & Trade-offs (one-liners)
- Sony WH-1000XM5: stronger smart features, LDAC; no wired 24-bit/96kHz focus.
- Bose QuietComfort Ultra: best-in-class ANC comfort; fewer hi-res angles.
- Bowers & Wilkins PX7 S2e: lush tuning; LDAC on some markets.
- Apple AirPods Max: Apple ecosystem perks; no hi-res over Bluetooth; heavy.
- Sennheiser Momentum 4: cheaper now; similar fit, but no bundled transmitter or parametric EQ.
Ports, Codecs, and Upgrades
You get USB-C, 3.5 mm, and Bluetooth. The big quality play is wired: up to 24-bit/96kHz without needing a separate DAC/amp. For wireless, the USB-C dongle adds aptX Adaptive to many phones that don’t support it natively useful given only a fraction ship with hi-res codecs. If you need LDAC specifically, look to rivals.
What matters for headphones (not “display”)
For this category, care about driver quality, ANC behavior, microphone clarity, fit, and software control (parametric EQ). The HDB 630 leans into midrange clarity and customization rather than heavy “wow” bass by default.
Battery & Charging Expectations
Plan on multi-day use: up to 60 hours with ANC on, with ~7 hours from a 10-minute charge for emergencies. That’s long-haul-flight friendly and rare at this tier.
Warranty & After-Sales in USA
USA: Standard Sennheiser limited warranty via authorized retailers; keep the proof of purchase and check return windows (often 14–30 days).
Where to Buy & Timing
Pre-orders have opened; global shipping starts October 21, 2025. If you’re price-sensitive, watch for holiday promos, but first-month discounts on brand-new flagships are uncommon.
