What Users Say

How It Compares

vs. Sennheiser Momentum 4 Wireless

Advantages

✓HDB 630 provides up to 60 hours of battery life versus the shorter runtime of Momentum 4.
✓Supports high‑resolution wireless codecs (aptX HD, aptX Adaptive) and USB‑C high‑res playback not emphasized for Momentum 4.
✓Includes parametric EQ and crossfeed via the Smart Control Plus app for advanced sound customization.

Disadvantages

✗HDB 630 weighs 311 g, which is 18 g heavier than the 293 g Momentum 4, leading to more headband pressure.
✗Comfort is reported as less optimal for larger heads compared to the lighter Momentum 4.

Choose the HDB 630 if battery life, high‑res audio, and tuning flexibility are top priorities; choose Momentum 4 if you need a lighter, more comfortable pair for extended wear.
