Sennheiser Momentum True Wireless 4 Review 2026: Sound First, Everything Else Second

The short answer

The Sennheiser Momentum True Wireless 4 are the audiophile’s earbuds: if sound quality is your top priority, independent reviewers consistently rank the MTW4 above Sony, Bose, and Apple for pure fidelity. The 7mm TrueResponse drivers, aptX Lossless support, and Sennheiser’s Sound Personalization deliver a detailed, natural presentation that flatters everything from classical to hip-hop. List price is $299.95, but street prices have fallen to around $199 — outstanding value for this level of audio.

The trade-offs are real, though: ANC that’s merely good (not Bose/Sony level), a bulky design and large case, and call quality that lags the competition. There’s also a successor to weigh — the Momentum True Wireless 5 launched September 2026 at $299.95 with Bluetooth 6.0, Dolby Atmos with head tracking, and more microphones. At $199, the MTW4 is a superb buy for music-first listeners; at full price, the MTW5 deserves a serious look instead.

What defines the MTW4 is its philosophy: Sennheiser spent the engineering budget on the things that make music sound better — the transducer, the codecs, the personalization — and accepted “good enough” everywhere else. If you share that priority ranking, these are the best earbuds in this roundup. If you don’t, the compromises will annoy you daily.

This is a research-based review. We have not tested the Sennheiser Momentum True Wireless 4 hands-on; every fact below comes from the manufacturer’s published specs, pricing, and independent reporting. Prices and specs checked September 30, 2026.

Key specs

Price and availability

Sennheiser’s list price is $299.95, but the MTW4 routinely sells for ~$199 at Amazon and other retailers in 2026 — a 33% discount that makes them cheaper than every other flagship here. They’re widely available in Black Copper, Metallic Silver, and Graphite. Given the September 2026 launch of the Momentum True Wireless 5 (also $299.95, with Bluetooth 6.0, Dolby Atmos with head tracking, 4 mics per bud, and up to 40 hours case total), expect MTW4 discounts to deepen further.

At $199, the MTW4 compete with mid-range buds on price while sounding like flagships — that’s the entire value proposition in one sentence. Just confirm you’re buying the “4” and not old “3” stock — the MTW3 still floats around at ~$170 and lacks multipoint, LE Audio, and the newer codec stack. And if you’re tempted by the MTW5’s Dolby Atmos and Bluetooth 6.0, weigh whether those features are worth the extra ~$100 to you; for pure stereo music listening, the MTW4’s core audio performance remains superb.

What it’s good at

• Best-in-class sound: TechRadar, SoundGuys-adjacent testing, and multiple reviewers call the MTW4 the best-sounding true-wireless earbuds — detailed, balanced, and natural, with aptX Lossless delivering bit-perfect wireless audio on compatible Android phones. The 5 Hz–21 kHz response and vanishingly low distortion are measurable, not marketing.
• Most future-proof codec support: aptX Lossless, aptX Adaptive, LC3, LE Audio, and Auracast — no other earbud in this roundup covers this much wireless-audio ground. Whatever your phone supports now or next year, these speak its language.
• Sound Personalization that works: The app’s guided hearing test builds a tuning profile matched to your ears — reviewers consistently say it produces a noticeably better result than the flat default. It takes a few minutes in the Smart Control app and is the single best thing you can do with these buds.
• Strong battery: 7–7.5 hours per charge and 30 hours total is competitive with the best in class, and independent standardized tests confirm the rated figures hold up in practice.
• Solid durability: IP54 dust and splash resistance beats Sony and Bose on paper — meaningful for commuters and anyone caught in weather.
• Multipoint included: Connect to two devices at once — something the MTW3 notably lacked, and a genuine quality-of-life feature for laptop-plus-phone users.

Where it falls short

• ANC is a step behind: Reviewers rate the noise cancellation around 7.5/10 versus 9+ for Bose and Sony — fine for offices and city streets, less convincing on planes and trains. If silence is the mission, look elsewhere.
• Bulky and less comfortable: At 6.2 g per bud with a large, pocket-filling case, they’re among the chunkiest flagships; long-session comfort trails Sony and Apple, and small ears may struggle.
• Weak call quality: Consistently rated the poorest of the flagships for voice calls — wind and background noise overwhelm the mic array, making these a poor choice for frequent callers.
• iPhone users miss the point: aptX Lossless and the advanced codecs are Android-only; on iOS you get AAC, erasing the MTW4’s biggest advantage over AirPods.

Who should buy it

Android users who put audio fidelity above all else — Tidal/Qobuz subscribers, FLAC collectors, and anyone with an aptX Lossless-capable phone. At ~$199, the MTW4 deliver flagship sound for mid-range money, making them the best pure-value pick for music lovers in this roundup. If your listening is 90% music and 10% everything else, the trade-offs barely register.

Who should skip it

Travelers who need maximum ANC (buy Bose), frequent callers (buy AirPods Pro or Bose), iPhone users (the codec advantage vanishes on iOS — AirPods are the better buy), and anyone with small ears sensitive to bulky buds. If the MTW5’s Dolby Atmos, Bluetooth 6.0, and improved mics appeal, it’s worth comparing at $299.95 before settling.

Verdict

4.5 / 5 — The best-sounding earbuds in the roundup at a street price that undercuts everything else. ANC, calls, and bulk are the prices you pay for that fidelity — and for music-first listeners, they’re prices worth paying. At $199, nothing else delivers this much audio per dollar.

FAQ

What’s the difference between the MTW4 and the new MTW5?

The September 2026 MTW5 adds Bluetooth 6.0, Dolby Atmos with head tracking, 4 mics per bud (including a bone-conduction mic), up to 12 hours ANC-off battery, 40-hour case total, and improved call quality — at the same $299.95 list price. The MTW4 counters with a ~$199 street price and essentially the same core sound quality.

Do they support aptX Lossless on iPhone?

No — aptX codecs are Android-only (and need a phone that supports aptX Lossless specifically; many support Adaptive but not Lossless). iPhones connect via AAC, so iOS users don’t get the MTW4’s headline audio feature and should consider AirPods instead.

How good is the noise cancellation really?

Good, not great. It handles offices, cafés, and city streets well but can’t match Bose or Sony on planes and trains. Sennheiser rates it at up to ~90% ambient-noise reduction; independent reviewers place it a clear tier below the ANC leaders.

Is the Sound Personalization feature worth using?

Yes — reviewers consistently say the guided hearing test produces a noticeably better-tuned sound than the flat default, adapting to your personal hearing profile. It takes a few minutes in the Smart Control app and is the single best thing you can do with these buds.
