Sennheiser MOMENTUM True Wireless MTW4

The Sennheiser MOMENTUM True Wireless 4 delivers some of the best sound quality we've ever measured in wireless earbuds, with aptX Lossless support and a mic that tops our charts. Battery life is solid at 30 hours total, and the ANC is elite. But build quality is a concern, touch controls are unreliable for some, and the price is premium. If you prioritize audio fidelity above all else, these are a top pick. Just shop around, because prices vary wildly from $103 to $360.

Let's talk about what these earbuds do well, because the sound really is exceptional. The 7mm dynamic driver paired with Sennheiser's TrueResponse system delivers a frequency response from 5Hz to 21kHz, which is wider than most human hearing and gives you deep, controlled bass without muddying the mids. The treble is refined rather than harsh, which is a common complaint with lesser earbuds that boost the highs to fake detail. The support for aptX Lossless is the real differentiator here. Most wireless earbuds compress audio to fit through Bluetooth's limited pipe. With a compatible source, these can transmit audio bit-by-bit without that compression, which is a genuinely rare trick. Even on standard AAC or SBC, the tuning is so well done that most people will notice the difference immediately.

The ANC is adaptive and hybrid, meaning it uses both feedforward and feedback mics to adjust to your environment on the fly. In our testing, it lands in the top 6 percent of all earbuds we've measured. That's genuinely strong, though some owners in the user reviews feel it doesn't quite match Sony or Bose at blocking out low-frequency rumble like airplane engines. The transparency mode is also well-implemented, letting in outside sound without that artificial, tinny quality you get on cheaper buds. Call quality is a standout. The six-mic array with noise cancellation puts these at the absolute top of our charts for mic performance. If you spend a lot of time on calls in noisy environments, this is a legitimate reason to pick these over almost anything else.

The most direct competitor here is the Sony WF-C710N. Sony's earbuds have a reputation for class-leading ANC, and in our testing, they do edge out the Sennheiser in that specific category. But the Sennheiser fights back with better sound quality and a more refined, audiophile-friendly tuning. If you're a commuter who wants maximum noise isolation, Sony might be the better pick. If you're a music lover who wants to hear every detail in a recording, the Sennheiser wins. The Apple AirPods Pro 3rd Generation is another obvious rival, especially if you're in the Apple ecosystem. The AirPods have seamless integration with iPhones and Macs, and their transparency mode is still the gold standard. But the Sennheiser's sound quality is a step above, and the mic performance is better for calls.

The Technics EAH-AZ100 is a sleeper pick that deserves more attention. Technics has a similar audiophile pedigree, and their earbuds offer excellent sound with LDAC support. The Samsung Galaxy Buds3 Pro is a solid all-rounder with good ANC and a comfortable fit, but it doesn't match the Sennheiser's raw audio fidelity. And if you're on a budget, the JLab JBuds Pods ANC is a fraction of the price, though you're giving up a lot of sound quality and build refinement. The Sennheiser sits in a sweet spot for people who prioritize audio quality above all else, but it's not the best choice for everyone.

Here's where things get interesting. The MOMENTUM True Wireless 4 is not cheap. In fact, the affordability score in our database puts it in the bottom 7 percent of all wireless earbuds. That's a polite way of saying these are expensive. But the pricing is also all over the map depending on where you shop. In the US, we're seeing prices from $103 to $360 across 26 listings. That's a $257 spread, which is wild. If you're paying $360, you're getting a great-sounding pair of earbuds but you're also paying a serious premium. If you can find them closer to $103, that's a completely different value proposition. In Canada, the spread is CAD 230 to CAD 430 across 10 listings, a CAD 200 difference. The lesson here is simple: shop around. Don't just grab the first listing you see.

At the high end of that range, you're competing directly with the Sony WF-1000XM5 and the Apple AirPods Pro 3rd Generation. Both of those have stronger brand recognition and, in Sony's case, arguably better ANC. At the low end, if you can snag these for around $100, you're getting flagship-level sound for mid-range money, and that's a steal. The value equation really depends on which price you actually pay.

The Sennheiser MOMENTUM True Wireless 4 is the kind of product that makes you remember why Sennheiser has the reputation it does. This is a company that has been making audio gear for decades, and these earbuds feel like a statement piece. The headline here is the sound. Sennheiser's TrueResponse transducer system, a 7mm dynamic driver, and support for aptX Lossless and aptX Adaptive mean this is one of the few pairs of wireless earbuds that can genuinely claim to deliver bit-perfect audio. If you're the type of person who has a folder of FLAC files and gets annoyed when a Bluetooth connection crushes the life out of a good recording, this is aimed squarely at you.

But these aren't just for audiophiles. The feature list is stacked. You get adaptive ANC, a transparency mode, Bluetooth 5.4 with LE Audio and Auracast support, multipoint connectivity, and a six-mic array for calls. Battery life is solid at 7.5 hours from the buds and 30 hours total with the case, plus Qi wireless charging and a quick-charge feature that gives you an hour of playback from eight minutes on the charger. The IP54 rating means they'll shrug off sweat and light rain, though the fitness score in our database suggests you shouldn't treat them like dedicated workout buds.

The interesting tension here is between the spec sheet and the real-world experience. On paper, these are near-flagship in almost every category. In our database, the mic quality is the best we've seen, sound is in the top 2 percent, and connectivity and ANC are both elite. But the build quality score is mediocre, and the user sentiment score of 72 out of 100 tells a more complicated story. People love the sound, but a meaningful number of owners have run into durability and connectivity gremlins. That's the story we're going to dig into.

If you're hard on your gear, these are probably not for you. The build quality score in our database is in the bottom third, and a meaningful number of owners have reported durability issues like one earbud dying or the case failing. If you toss your earbuds in a bag without a case or you're rough on your tech, the Sony WF-C710N or Apple AirPods Pro 3rd Generation are built to take more abuse. The bulky case is also a turn-off if you want something that slips into a pocket easily.

If you're a fitness enthusiast, look elsewhere. The fitness score of 55.5 out of 100 is the weakest area for these earbuds, and the fit can be hit-or-miss for some ear shapes. You'd be better off with a dedicated sports earbud like the JLab JBuds Pods ANC or something with a more secure wing design. And if you're on a tight budget, the affordability score in the bottom 7 percent means these are a luxury purchase. There are plenty of solid options under $100 that will get you 80 percent of the sound quality for a fraction of the price.

If you care about sound quality above everything else, the Sennheiser MOMENTUM True Wireless 4 is one of the best pairs of wireless earbuds you can buy right now. The aptX Lossless support, the TrueResponse driver, and the overall tuning put these in the top 2 percent of all earbuds we've tested. The mic quality is also the best we've seen, which makes these a great pick for people who take a lot of calls. The ANC is strong, the battery life is solid, and the fit is comfortable for most people. This is a flagship product that delivers on its core promise.

But there are real caveats. The build quality score is mediocre, and a meaningful number of owners have reported durability issues. The touch controls are finicky, and some users have experienced connectivity problems. The charging case is bulky, and the price is premium. If you're hard on your gear or you want something that just works without fiddling, the Sony WF-C710N or Apple AirPods Pro 3rd Generation might be a safer bet. But if you're willing to put up with some quirks for the sake of exceptional sound, these are hard to beat.
