Sennheiser HDB 630 vs MOMENTUM 5

The Sennheiser HDB 630 and Sennheiser MOMENTUM 5 are similar headphones with differentiating characteristics that can pull you in either direction. The MOMENTUM 5 have a warm tuning that emphasizes the low-bass rumble of movie soundtracks more than the balanced HDB 630, but one tuning isn't necessarily better than the other and comes down to preference. The HDB 630 stands out thanks to convenient access to a parametric EQ and crossfeed features in the app, and they have a longer battery life, though both headphones have over 50 hours with ANC on. You also get the Sennheiser BTD 700 wireless dongle so you can listen to high-quality or low-latency audio streams on iPhones without worrying about Bluetooth codec compatibility. On the other hand, the MOMENTUM 5 are more affordable and offer virtual surround support for more immersive listening via Dolby Atmos.
