Sennheiser MOMENTUM M4AEBT Review

Skip these. The Sennheiser MOMENTUM 4 Wireless has a fatal flaw: comfort ranks in the worst 4% of headphones we've tested. Combined with mediocre sound and noise cancellation, it's hard to justify its $270+ price when better, more comfortable options exist.

The Sennheiser MOMENTUM 4 Wireless headphones promise a premium experience with their 60-hour battery life and aptX Adaptive support. But in our testing, the numbers tell a more nuanced story. They land squarely in the middle of the pack for sound and noise cancellation, and their comfort score is one of the worst we've seen, which is a big deal for headphones you're supposed to wear all day.

Let's talk about what matters most: the listening experience. The sound quality sits in the 36th percentile, which is just okay. It's not bad, but it's not the standout audiophile experience the marketing suggests. The Adaptive Noise Cancellation (ANC) scores the same, at 36th percentile. It'll block some noise, but it's not going to compete with the leaders. The battery life, despite the 60-hour claim, only ranks in the 14th percentile. That suggests real-world usage drains it faster than advertised, or competitors have simply gotten much better. The mic quality is about average at the 53rd percentile, so your calls will be fine, just not exceptional.

Priced between $269 and $280, the MOMENTUM 4 sits in premium territory. For that money, you're getting a decent feature set with aptX Adaptive and a nice case, but the core performance metrics—sound, ANC, and critically, comfort—don't justify the premium tag. You're paying for the Sennheiser name and some nice-to-haves, not class-leading performance.

Stacked against the competition, the gaps are clear. The Sony WF-1000XM5 and Bose QuietComfort Ultra are in a different league for noise cancellation and generally score higher for sound. The Technics EAH-AZ80 often delivers better audio fidelity at a similar price. Even Apple's AirPods Pro, while in a different form factor, offer a more cohesive and comfortable experience with superior ANC. The MOMENTUM 4's main advantage is aptX Adaptive support for Android users, but that's a niche win against broader weaknesses.

Avoid these if comfort is a priority—the data is brutally clear. Also skip if you need best-in-class noise cancellation for commuting or flights, or if you're looking for the absolute best sound quality at this price. Fitness users should definitely look elsewhere, as this is their weakest-scoring category.

We can't recommend the MOMENTUM 4 Wireless for most people. The dealbreaker is comfort scoring in the 4th percentile—headphones you don't want to wear are bad headphones. When you combine that with average sound and ANC, there's just not enough here to choose it over the established leaders from Sony, Bose, or even Technics, unless you're an Android user absolutely married to aptX Adaptive and don't mind the fit.
