Sennheiser Momentum 4 Wireless vs Sony WH-XB910N Extra Bass
The Verdict
Sennheiser's Momentum 4 and Sony's WH-XB910N target different priorities within the over-ear wireless headphone market. Battery life represents their most dramatic difference: the Momentum 4 delivers a staggering 60 hours with ANC enabled, compared to Sony's 30 hours, making it exceptionally practical for travel or infrequent charging. Quick charging favors Sennheiser as well, offering 6 hours of playback from just 10 minutes versus Sony's 4.5 hours. Sound character diverges significantly, with Sony emphasizing extra bass through its 40mm driver and dedicated Extra Bass mode, appealing to bass enthusiasts and EDM listeners. Sennheiser's 42mm driver focuses on balanced, personalized audio via its Smart Control app for sound customization. At 293g versus 252g, the Momentum 4 weighs slightly more but delivers proportionally longer usage per charge. Sony edges ahead on codec support with LDAC for superior wireless audio quality, though Sennheiser includes aptX Adaptive. Both offer multipoint pairing, ANC, and Bluetooth 5.2 connectivity. For listeners prioritizing marathon battery life and flexibility, Sennheiser wins decisively. Sony suits buyers wanting superior bass response, lighter weight, and better wireless audio codecs at a $131 lower price point. Your choice depends on whether battery endurance or immediate sonic preference matters more.
