The Battle of Two Premium Sennheiser Headphones

Sennheiser has launched two of its strongest wireless headphones in recent years — the HDB 630, a compact premium model built for accuracy, and the Momentum 4, a stylish and powerful all-rounder with long battery life. Both sit in different price zones, but they target the same listener: someone who wants top-class sound, comfort, and battery endurance.

The HDB 630 comes in at ₹44,990, while the Momentum 4 Anniversary Edition sits at ₹25,990. The gap makes this comparison even spicier.

Design: Compact Precision vs Artistic Flair

The HDB 630 uses premium Ideatex™ leatherette, smaller earcups, and a compact studio-inspired shape built for long listening hours. The clamping force stays light yet secure, making them comfortable over long sessions.

Meanwhile, the Momentum 4 remains sleek, lightweight, and padded for comfort during travel, binge watching, or work. Momentum 4 also comes in Anniversary Edition with graffiti-inspired artwork created by German artist Bond Truluv. It blends Sennheiser’s 80-year heritage with modern street aesthetics.

Design Verdict:
HDB 630 wins for pure comfort and compactness. Momentum 4 wins for unique style. Choose based on taste.

Controls: Power vs Convenience

The HDB 630 offers Sennheiser’s most advanced control system yet. The Smart Control Plus app features a full Parametric EQ with mastering-grade precision, plus Crossfeed taken from the iconic HE 1 system. You get audiophile-level tuning tools that no mainstream headphone offers at this price.

The Momentum 4, on the other hand, keeps things simple with touch controls, auto-shutdown, on-head detection, and custom ANC modes. The app adds presets and manual sliders for quick adjustments, making the experience more user-friendly.

Controls Verdict:
HDB 630 for deep customization. Momentum 4 for ease.

Connectivity: Hi-Res Master vs Multi-Device Flex

The HDB 630 supports aptX Adaptive, aptX HD, USB-C hi-res playback, analog input, and includes the BTD 700 dongle to boost high-res compatibility from 16% to over 80% of devices. This improves clarity and detail noticeably.

The Momentum 4 offers Bluetooth 5.2 with aptX Adaptive, AAC, SBC, and multi-device connection support. You also get sound zones, device management, and customizable EQ controls inside the app.

Connectivity Verdict:
HDB 630 takes the lead thanks to its hi-res signal chain and bundled dongle.
