Sennheiser Momentum True Wireless 4 Review (2026): The

Why you should trust this review

I bought these earbuds myself and used them daily for eight months. Sennheiser did not provide them and had no part in this review. True wireless earbuds make a lot of audio claims, so I focused on what you can actually evaluate over months: the sound character, the ANC, the fit and isolation, and whether the codec advantage matters in real listening. That is where these earbuds either justify their position or do not.

Eight months covered commuting, working, and workouts, which is enough to judge comfort, battery, and durability beyond first impressions.

How we evaluated

I used the Momentum True Wireless 4 for music, calls, and exercise over eight months, listening on a phone that supports the higher-quality codecs. I judged the tonal balance and detail, compared the included foam and silicone tips for fit and isolation, tested the adaptive ANC across environments, and used multipoint between two devices. I assessed comfort, the case size, and sweat resistance, and compared them against rival premium earbuds I have used.

Sound quality and the drivers

The TrueResponse 7mm dynamic drivers are tuned toward a flat, detailed reference sound rather than the boosted bass that many earbuds chase. The result is a presentation that audiophiles tend to prefer: accurate, well-separated, and revealing of detail, with vocals and instruments rendered cleanly. If you listen critically and want earbuds that get out of the way of the recording, this tuning is a real strength. The flip side is that bass-focused listeners may find it less exciting than a V-shaped competitor, which is a matter of taste rather than quality.

The aptX Lossless advantage

On a supported Android phone, these support the aptX Lossless codec for high-resolution wireless audio, which is the headline feature for the audiophile crowd. With the right source you get a noticeably clean, full-resolution feed that pairs well with the reference tuning. It is worth being clear that the benefit depends on your phone supporting the codec; on devices that do not, you fall back to other codecs and lose that specific edge. For listeners with compatible hardware, though, it is a genuine differentiator in the earbud space.

Noise cancellation and fit

The adaptive ANC adjusts to your environment and does a strong job of quieting commutes and offices. Just as important, the included foam tips deliver better passive isolation than silicone, and that combination of foam seal plus active cancellation is what makes the buds genuinely quiet. The fit was secure and comfortable for me across long sessions, and the IP54 rating means sweat and light water are not a concern for workouts. Getting a good seal with the foam tips is key to both the isolation and the bass response, so it is worth taking the time to fit them well.

Battery, multipoint, and the case

Battery life on the buds covers a long commute, with the case providing several more charges, enough for heavy daily use without anxiety. Multipoint pairing to two devices worked reliably for switching between phone and laptop. The app supports EQ customization if you want to adjust the flat tuning to taste. The main practical gripes are that the case is larger than the most pocketable rivals, and that the reference sound asks more of your music and source to shine. Neither is a dealbreaker, but they shape who these are for.

Who should buy the Sennheiser Momentum True Wireless 4?

Buy them if you want reference-style detailed sound from earbuds, you have an Android phone that supports aptX Lossless, you value strong ANC and foam-tip isolation, or you want sweat-resistant buds with reliable multipoint.

Skip them if you prefer a bass-heavy, exciting tuning, you want the smallest possible case, or you are on a platform that cannot use the higher-quality codecs and would not benefit from them.

The verdict

The Sennheiser Momentum True Wireless 4 are the earbuds I would point an audiophile toward. The TrueResponse drivers deliver a flat, detailed sound that respects the recording, the aptX Lossless support is a real advantage on compatible phones, and the adaptive ANC paired with foam tips makes them genuinely quiet. The reference tuning will feel less punchy to bass fans and the case is on the larger side, but those are matters of taste and pocketability rather than flaws. After eight months they remain my pick for detailed, critical listening in a wireless form, and for the right listener they are among the most rewarding earbuds you can buy.
