Amazon India Product Listing: Sennheiser HDB 630 Hi-Res Wireless Headphones : 42 mm Drivers, aptX™ HD & aptX™ Adaptive, Active Noise Cancellation, 60H Battery,Parametric Equalizer & Crossfeed Feature, BTD 700 USB-C Dongle Included
Sennheiser's HDB 630 is built for people who take their audio seriously but don't want to be tethered to a desk. At ₹48,990 (₹54,990 M.R.P.), it's positioned as an audiophile wireless headphone—something most brands talk about but rarely execute well.
Neutral Tuning From a Closed-Back Design
Most closed headphones sound boxy or bass-heavy. The HDB 630 breaks that mold with a neutral frequency response that emphasizes clarity over color. The 42mm driver handles fast, controlled bass without masking vocals, lifelike mids with a tasteful upper-mid lift for presence, and controlled treble that doesn't fatigue. This is the real value proposition—you get audiophile sound tuning from a wireless headphone.
High-Res Wireless, Actually
The included BTD 700 USB-C dongle supports aptX HD and aptX Adaptive, letting you stream high-resolution audio from phones, tablets, and laptops. You can also connect via USB-C or analog 3.5mm for lossless listening up to 24-bit/96kHz. The flexibility is rare in this segment.
60-Hour Battery Changes the Game
That's not exaggeration—you can literally go a week without charging. For travel, work marathons, or binge sessions, this eliminates charging anxiety entirely. The battery endurance justifies the weight and build.
Parametric EQ and Crossfeed Give You Control
The parametric equalizer available in the app lets you adjust specific frequencies precisely, not just preset bands. Crossfeed smooths out hard-panned stereo mixes from older recordings. These aren't gimmicks; they're tools for serious listeners who want to shape their sound.
Adaptive Noise Cancellation Without the Sonic Cost
The ANC is powerful but doesn't degrade clarity or dynamics—common trade-offs in cheaper headphones. Transparency mode lets you hear surroundings when needed.
Comfort Built for Long Sessions
311g is light enough for all-day wear. Generously sized earcups with synthetic leather pads, a refined headband, and gentle clamping force mean you won't feel fatigued after hours of listening. This is the detail that separates daily drivers from showpieces.
