Sennheiser Momentum True Wireless 4 Earbuds Review
Audiophile-tuned earbuds with rich, detailed sound and seriously good noise cancellation.
These are the earbuds you buy when you actually care how your music sounds — rich, textured audio and noise cancellation good enough to make a cramped airplane cabin disappear.
What the Momentum True Wireless 4 actually is
Sennheiser's Momentum True Wireless 4 (MTW4) is the company's flagship pair of premium ANC earbuds, sitting in the $200–$300 range alongside the AirPods Pro and Bose QuietComfort Ultra. The pitch is simple: take Sennheiser's reputation for detailed, grown-up sound and cram it into something that disappears into a pocket.
You get a 7mm dynamic driver per side, support for high-res codecs including aptX Adaptive and aptX Lossless (with the right phone), Bluetooth 5.4 with Auracast support, and a wireless charging case. On paper it's loaded; in practice, the headline is still the sound.
How they sound — and why audiophiles care
This is where the MTW4 earns its keep. Out of the box the tuning leans warm but resolving — bass has weight without smothering the mids, and there's real detail in vocals and acoustic textures that cheaper buds smear over. Put on a dense recording and you can pick out instruments that lesser earbuds blend into mush.
The companion app's parametric-style EQ is genuinely useful, not a gimmick. If you want more sparkle up top or a flatter, studio-leaning signature, you can dial it in and it sticks. With aptX Lossless on a compatible Android phone, the ceiling goes higher still — though most people on iPhones won't unlock that and will be perfectly happy anyway.
Noise cancellation and daily use
The ANC is the second reason to buy these. It's not quite the all-conquering silence of the Bose QuietComfort Ultra, but it's close, and it crushes the steady drone of planes, trains, and office HVAC. Transparency mode is natural enough to leave on for conversations without yanking a bud out.
Day to day, they're comfortable for a few hours thanks to a small, light shell and four ear-tip sizes, with battery life landing around 7 hours with ANC on and roughly 28–30 hours total with the case. Touch controls are responsive, multipoint pairing works reliably, and call quality is solid if not class-leading in heavy wind.
The cons worth knowing before you buy
Fit is the main caveat. The MTW4 sits a bit proud in the ear and the touch surface is sensitive, so some people fight accidental taps and a less-than-locked-in seal during workouts. They're rated IP54, which handles sweat and light rain, but they're not built as gym-first buds.
Price is the other sticking point. At the top of their range they cost as much as the biggest names, and the value-conscious can get 85% of the experience for less. You're paying a premium specifically for that Sennheiser sound and codec support.
Who should buy them — and who shouldn't
Buy the Momentum True Wireless 4 if sound quality is your top priority, you listen to a wide range of well-recorded music, and you want strong ANC for commuting or travel. Android users with aptX Lossless phones get the most out of them.
Skip them if you mostly want gym earbuds with a vault-tight fit, if you live entirely in the Apple ecosystem and value seamless AirPods integration over sound nuance, or if you simply want the best ANC at any cost — the Bose edges ahead there.
Verdict
The Momentum True Wireless 4 is one of the best-sounding pairs of true wireless earbuds you can buy, backed by ANC that genuinely competes at the top. The fit won't suit everyone and the price is steep, but for listeners who care about audio first, these are an easy recommendation.
Frequently asked questions
- Are the Sennheiser Momentum True Wireless 4 good for the gym?
- They're rated IP54 so they'll survive sweat and light rain, but the fit isn't as secure as dedicated sport buds and the touch controls can trigger accidentally during movement. They're better suited to commuting and everyday listening than intense workouts.
- How is the battery life on the Momentum True Wireless 4?
- Expect around 7 hours per charge with ANC on, and roughly 28–30 hours total with the charging case. The case also supports wireless charging and fast top-ups.
- Do the Momentum True Wireless 4 support lossless audio?
- Yes, via aptX Lossless and aptX Adaptive, but only when paired with a compatible Android phone. iPhone users get AAC, which still sounds very good but won't access the high-res lossless modes.
