Introduction
Let’s dig into the HDB 630 from a few angles you don’t usually see in press releases. I’ll show you who actually gets the most out of these, how they fit into India’s audiophile scene right now, and whether the price makes sense.
Price and Where to Buy in India
Sennheiser priced the HDB 630 at Rs. 54,990. If you pre-book, you pay Rs. 44,990 and get a free Accentum Open TWS (worth Rs. 12,990) thrown in. Pre-booking runs through December 4, and you can get them on the Sennheiser India website, Amazon, Headphone Zone, Audio Store, Concept Kart, and a few select offline shops.You get a two-year warranty, which isn’t nothing—especially if you’re planning to use these every day.

What Sets the HDB 630 Apart in India?
Most premium headphones promise “great sound.” Sennheiser’s doing something different here. The HDB 630 is tuned for neutrality—no fake bass boost or hyped-up highs. It’s made for people who care about hearing music as it actually sounds in the studio, not just for casual listening. That puts it in a different league from the Sony WH-1000XM5 or Bose QC Ultra, which are fantastic for everyday use but don’t really aim for reference-grade accuracy.
1. Studio-Grade Tuning Tools
The Smart Control Plus app gives you a parametric EQ—real control over frequency, bandwidth, and filter type. That’s not something you find on most wireless headphones in India. If you’re mixing, recording, or podcasting, this lets you dial in your sound with actual precision, wherever you are.2. Crossfeed for Classic Recordings
Crossfeed might sound technical, but here’s the deal: it makes old, hard-panned recordings sound more natural, almost like you’re listening to speakers. Think early Bollywood soundtracks, vintage rock, or rough old studio masters. Modern headphones usually skip this feature because today’s mixes don’t need it, but Sennheiser added it for people who care about authenticity.3. True High-Resolution—Wired and Wireless
A lot of brands talk up “hi-res” but then only deliver when you plug in a cable. The HDB 630 actually goes high-res in every mode: USB-C (24-bit/96 kHz), Bluetooth (with aptX Adaptive and the BTD 700 dongle), or even classic analogue cable. That dongle is important—most Indian smartphones have Bluetooth that just isn’t up to the job for real high-res audio.Acoustic Design Tweaks
Sennheiser reworked the magnet mesh, the back-volume chamber, and the baffle mesh. It’s the kind of engineering that strips away subtle high-frequency distortion. If you’re into classical, jazz, or picking apart studio stems, you’ll actually hear more detail—layers and separation that get lost on lesser headphones.Battery Life and Durability
You get up to 60 hours of battery—way ahead of most rivals. A 10-minute quick charge nets you seven hours of use. Sennheiser says they’ve tested these through 500 charging cycles, so they’re built to last.Comfort and Build
The HDB 630 takes what works from the Momentum 4 series and makes it better: it's lighter at 311 g, has softer leatherette earpads, has less clamping force, and has earpads you can actually replace. If you travel, work long hours, or just want something you can wear all night, you’ll feel the difference.

Does the HDB 630 work for Zoom calls and meetings?
Absolutely. The mics are solid, Bluetooth 5.2 is stable, and your voice stays clear—even if you’re in a noisy office.
Can you swap out the earpads?
Yes, the leatherette earpads are replaceable. That’s a big plus for longevity.Which devices support high-res playback with the dongle?
Laptops, desktops, and many smartphones work with the BTD 700 dongle. It keeps the audio quality consistent, even if your phone’s Bluetooth is subpar.How does the ANC compare to Sony and Bose?
Sony and Bose still win for sheer noise-canceling power. Sennheiser focuses more on keeping the sound accurate than on blocking out every last decibel.Can you use the headphones without the app?
Sure. They’ll work just fine out of the box. But if you want deep tuning and features like parametric EQ, the app is where that happens.Conclusion

You get that clean, studio-level audio, a bunch of smart tuning features, crisp hi-res playback, and a battery that keeps going. Sure, it isn’t the cheapest out there, but if you want precision and gear that lasts, it’s worth every bit.For pros, creators, and serious music lovers, the HDB 630 checks all the right boxes. It’s not just about flashy specs—it’s about rock-solid engineering you can use every day. Plus, the launch price and those free Accentum Open TWS earbuds make it even more tempting to grab one early.
