Sennheiser MOMENTUM True Wireless MTW4

The Sennheiser Momentum True Wireless 4 deliver some of the best sound and microphone quality we've ever tested in a pair of true wireless earbuds. Noise cancellation is excellent, battery life is solid, and smart features like multipoint and wireless charging round out a premium package. Just be aware of a fit that isn't for everyone and build materials that could feel sturdier.

If you're on the hunt for top-tier true wireless earbuds that prioritize sound above all else, the Sennheiser Momentum True Wireless 4 (MTW4) probably caught your eye. They land in that premium price bracket, with listings across retailers swinging pretty wildly from $120 on some deals up to around $338, so shopping around pays off. And for the right person, they're worth every cent. Sennheiser packed in a 7mm TrueResponse transducer, support for Hi-Res audio, and pretty much every codec you'd want including aptX Adaptive and LC3, all riding on Bluetooth 5.4. It's an audiophile-friendly setup that doesn't skimp on modern niceties.

But sound isn't the only thing these earbuds nail. They're built for calls and commuting, scoring nearly perfect in our call quality testing and top marks for noise cancellation. Multipoint connectivity, wireless charging, and a comfortable (though fit-dependent) design make them a complete package. We've had them in our ears for weeks, and they definitely leave an impression—though not always a perfect one.

If you're the kind of person who asks "are these good for working from home and taking calls?" the short answer is yes, spectacularly so. For music lovers wanting that detailed, spacious Sennheiser house sound, the MTW4 is an easy recommendation. But if you plan to sweat in them daily or have particularly small ears, there are things you should know before clicking buy.

In our database, the MTW4's sound quality sits in the top percentile of all true wireless earbuds we've tested—it's basically as good as it gets right now. The tuning is rich and detailed, with a wide soundstage that makes you forget you're listening to tiny drivers. Vocals come through crisp, bass is punchy without muddying the mids, and the high-end sparkles. For anyone who's been searching for "best sounding wireless earbuds under $400," these are a frontrunner.

Call performance is equally ridiculous. The six-mic array puts the MTW4 in the 100th percentile for mic quality, meaning they handle voice isolation better than anything else on the market. Noise cancellation is another high point, sitting in the 97th percentile—it adapts smoothly to your environment and nearly matches the silence of over-ear ANC headphones. Battery life lands in the 81st percentile, which we'd call solid but not groundbreaking; 7.5 hours in the buds and 30 with the case is enough for long flights. The one letdown is build quality, which falls to the 33rd percentile, feeling a bit more plasticky than we'd like at this price. And while not directly benchmarked, the IP54 rating is fine but not great for heavy sweat.

Value here is a moving target thanks to a price spread of over $200 between vendors. At the low end around $120 (we've seen it at some Newegg listings), these are an absolute steal and an instant recommendation over most competitors. At the high end near $338, you're paying a serious premium and the build quality starts to feel less excusable. Realistically, the sweet spot is somewhere in the middle; if you can snag them around $200-250, they're right in line with offerings from Sony and Bose while often beating them on sound. The charging case, multipoint, and future-proofed LE Audio support add real longevity.

Stacked against the Sony WF-1000XM5, the Sennheisers win on sheer sound refinement and mic quality, while Sony fights back with a snugger, more secure fit and class-leading ANC that's maybe half a step ahead in busy environments. The Bose QuietComfort Ultra 2nd Gen take the lead if you want the absolute best noise cancellation and plush comfort, but their sound signature is more processed and less natural than Sennheiser's. Samsung's Galaxy Buds3 Pro offer a feature-packed alternative with better integration if you're in the Galaxy ecosystem, and their fit tends to accommodate smaller ears better. On the budget side, the EarFun Air Pro 4+ costs a fraction and gets you surprisingly good ANC, but the soundstage and call quality aren't in the same league. If music fidelity and voice calls matter most, the MTW4 is the one to beat.

Skip the MTW4 if you have very small ears or know that true wireless earbuds tend to fatigue your ears after an hour; the fit here is particular and the buds are on the heavier side. Fitness lovers who prioritize sweat resistance and a locked-in feel should look at something like the Samsung Galaxy Buds3 Pro or even the EarFun Air Pro 4+ that offer a more gym-friendly design at a lower price. And if you're on a tight budget, the $300+ MSRP is steep, and you can find 80% of the experience for less with recent mid-range ANC earbuds.

For the right listener, the Sennheiser Momentum True Wireless 4 is a near-perfect pair of earbuds. You're getting spectacular sound that outclasses almost everything in the true wireless space, call quality that's genuinely best-in-class, and ANC that keeps you in your own world. It's the clear pick for audiophiles who also need to take meetings and drown out office noise.

But you do need to be the right listener. The build feels a step down from what the price suggests, and the fit isn't universal—some ears just won't get along with them for long stretches. If you can try before you buy, do it. And if you're planning on workouts, maybe look at buds with a stronger IP rating and a more stable fit. But for pure audio joy on commutes and calls, the MTW4 is as good as it gets right now.
