The Sennheiser MOMENTUM True Wireless 4 offers a broad set of listening features: adjustable sound, ANC, two-device Bluetooth connection and support for compatible Auracast broadcasts. It remains worth comparing at a suitable price even though Sennheiser’s US store now identifies it as an end-of-life model.
Its value depends on fit and the devices used with it. Advanced Bluetooth options are useful only when the source supports them, and the relatively substantial earpieces will not suit every ear. The everyday seal and controls deserve more attention than a list of codecs alone.
Sound and Noise Cancellation
- 7 mm dynamic drivers
- Adaptive ANC
- Five-band EQ and personalization
RTINGS found strong noise reduction and a warm balance in its original sample.1 That supports the MTW4 as a travel option, while the app provides room to adjust sound preferences. A secure seal matters before any equalization: if the tips move or fail to close the ear canal, bass and isolation can change together.
The supplied tip and fin sizes allow more adjustment than a single fixed shape. Try them independently on each side rather than assuming both ears need the same combination. Sound Personalization offers another way to choose a preferred balance; it should be treated as a listening preference tool rather than proof of objectively better sound.
Design and Comfort
- Approximately 6 g per earbud
- Four tip sizes and three fin sizes
- IP54 earbuds
The fins help stabilize the earpieces without requiring a deep fit from the tips alone. RTINGS found them stable but noted that the bulk could become uncomfortable for smaller ears.1 A secure earbud that creates pressure after an hour is still the wrong fit for a long journey.
IP54 applies to the earbuds, not the charging case. Dry them before returning them to the case, and keep the case away from splashes. The fabric-covered case also adds carrying bulk beyond the weight of either earpiece. A pocket check is worthwhile if these are intended to replace a smaller pair.
Connectivity
- Bluetooth 5.4 and multipoint
- aptX Adaptive / Lossless
- Auracast with current firmware
Two Bluetooth source devices can remain connected for switching between a phone and computer. The enhanced aptX modes require compatible source hardware and settings; an iPhone connection does not acquire aptX simply because the earbuds support it. Choose the model for benefits available with the devices actually used.
Auracast is now enabled through the appropriate firmware and companion app, despite older launch material describing it as a future addition. It lets the earbuds receive compatible nearby broadcasts, such as a shared television stream. Availability depends on a transmitter providing that stream, and it is separate from ordinary two-device pairing.
There is no analog input or USB audio mode.1 The case’s USB-C port supplies charging, with Qi charging as an alternative. Calls use the earbud microphones; RTINGS found that some surrounding noises could interfere with speech capture.1 Noise cancellation for listening and noise rejection for the caller are separate capabilities.
Battery Life
- Up to 7 hours with ANC
- Up to 7.5 hours without ANC
- Up to 30 hours including case
Sennheiser’s hardware specifications distinguish seven hours with ANC from seven and a half without it. The total thirty-hour figure includes returning the earbuds to the case for charging; it is not one uninterrupted listening session. The English guide reverses the two ANC labels, so the product specification and matching translated guide provide the clearer basis.
A short eight-minute charge is rated for up to an hour, while a full charge takes roughly an hour and a half under the stated conditions. Qi charging may take longer. Battery Protect limits the charge level to reduce time spent at full charge, trading some immediate runtime for the manufacturer’s longevity-oriented charging approach.
Alternatives
The MOMENTUM True Wireless 3 is the predecessor. The MTW4 adds the newer wireless platform and battery-system changes documented by Sennheiser, but a working earlier pair should be judged by its actual limitations. A newer feature is only a reason to replace it when the source or listening routine can use it.
Sony’s WF-1000XM5 is an alternative for a listener who prefers its fit or uses LDAC-compatible sources. It also offers Qi charging, while its earbud protection rating is IPX4. Compare comfort and source compatibility directly rather than assuming that one codec list establishes better sound for everyone.
Verdict
The MOMENTUM True Wireless 4 remains a useful discounted option for its ANC, sound adjustment and current Auracast support. It makes most sense when the fit is comfortable and its wireless features match the intended sources. Check the actual offer and current warranty terms instead of relying on launch-era promises.
