Sennheiser’s Momentum True Wireless series has consistently ranked among the best options for listeners who prioritize sound quality in premium wireless earbuds. The Momentum True Wireless 4 advanced that formula with aptX Lossless, Auracast, and balanced tuning, while the Momentum True Wireless 5 introduces a slimmer design alongside improved noise canceling and battery life. The newer model seems like the more complete package, but the similarities between these generations could make the Momentum True Wireless 4 a compelling alternative, especially if its price drops. How significant are the upgrades? Let’s compare the Sennheiser Momentum True Wireless 5 and Momentum True Wireless 4.

Look & Feel
The Momentum True Wireless 5 presents the most noticeable physical redesign the series has received in several generations. While the Momentum True Wireless 4 retained nearly the same shell as its predecessor, the fifth-generation model squeezes that familiar shape into a slimmer and sleeker housing. Removing the prominent outer rubber section gives the Momentum True Wireless 5 a cleaner appearance. More importantly, the narrower construction makes the earbuds feel less cumbersome. They rest more securely in the ear and remain comfortable over extended listening sessions. The Momentum True Wireless 4 is still comfortable, and its interchangeable fins provide additional stability. Its larger shell is more noticeable, however, and it lacks the streamlined feel of the newer model. The Momentum True Wireless 5 is the better choice for listeners who found previous Momentum earbuds too bulky.
Design and Functionality
Both earbuds use Sennheiser’s 7mm TrueResponse dynamic driver, so the Momentum True Wireless 5 does not introduce a fundamentally different transducer system. Instead, its functional improvements concentrate on isolation, calls, and long-term usability. Noise canceling on the Momentum True Wireless 4 is effective, but it never feels like the main attraction. It reduces a good amount of environmental noise, although its performance falls behind the strongest ANC earbuds in its class.
The Momentum True Wireless 5 offers a more noticeable improvement. Its stronger active noise canceling provides better isolation from major environmental distractions, while automatic wind-noise suppression makes it more effective outdoors. Four microphones per earbud, beamforming, AI-powered voice isolation, and a voice accelerometer also help produce clearer calls in noisy areas. Both generations work with Sennheiser’s Smart Control app. The Momentum True Wireless 4 offers adjustable ANC, EQ controls, customizable touch commands, and location-based Sound Zones. These features already make it a flexible earbud, but the Momentum True Wireless 5 surrounds that core experience with better isolation and more advanced microphone processing.
Bluetooth
Bluetooth performance is one of the biggest strengths of both models. The Momentum True Wireless 4 uses Bluetooth 5.4 with Qualcomm’s S5 Sound Gen 2 platform and Snapdragon Sound. Its codec selection includes aptX Lossless, helping compatible Android devices transmit higher-quality audio. Auracast support also brings expanded sharing and accessibility possibilities.
The Momentum True Wireless 5 moves to Bluetooth 6.0 and supports multipoint connectivity. Its codecs include SBC, AAC, aptX, aptX Adaptive, and aptX Lossless. These options allow the earbuds to accommodate standard iOS playback as well as higher-bandwidth listening from compatible Android devices. Moving from Bluetooth 5.4 to Bluetooth 6.0 gives the Momentum True Wireless 5 the technical advantage, but the practical difference may not be dramatic for every listener. The Momentum True Wireless 4 already offers an excellent wireless feature set and remains highly competitive.
Battery Life
The Momentum True Wireless 4 provides approximately seven and a half hours of playback, with the charging case extending total listening time to around 30 hours. An eight-minute quick charge supplies roughly one additional hour. Battery life is considerably more flexible on the Momentum True Wireless 5. It can deliver up to 12 hours with ANC disabled or approximately six hours with ANC active. The charging case extends total playback to as much as 40 hours, while the same eight-minute quick charge offers about one hour of listening.
Both cases support convenient charging, but the Momentum True Wireless 5 adds a particularly important long-term feature: replaceable batteries in the earbuds and charging case. That gives owners a way to extend the product’s usable lifespan once battery degradation becomes noticeable.
Soundstage
The Momentum True Wireless 4 creates a wide and accurate stereo image. Its presentation is relatively flat rather than dramatically holographic, but individual sounds occupy precise locations. This organization makes the earbuds easy to follow across dense arrangements, even if the stage does not project very far beyond the head. The Momentum True Wireless 5 follows a similar philosophy. It does not produce a massive wingspan, but its separation and depth are convincing. Instruments have enough room to breathe, and layered arrangements avoid becoming congested in the center. The presentation feels organized and immersive without relying on exaggerated width.
Dolby Atmos spatial audio gives the Momentum True Wireless 5 an additional listening mode, but it is not necessarily an improvement over standard stereo. It can pull carefully separated elements toward the center and make the image feel less natural. Stereo mode remains the best way to experience the earbud’s precise imaging. The Momentum True Wireless 4 may appear slightly wider, while the Momentum True Wireless 5 displays its layers with more depth and control. Neither has an overwhelming advantage, but the newer model feels a little more dimensional.
Low End
The Momentum True Wireless 4 delivers the thick, colorful bass response associated with Sennheiser’s wireless products. It has good impact and clarity without completely dominating the sound signature. The app’s bass-boost option can make the mid-bass too prominent, but manual EQ adjustments help bring out additional definition. Bass becomes more physical on the Momentum True Wireless 5. The low end has a smoother and deeper bloom, supported by subtle sub-bass extension and a richer mid-bass body. It carries greater weight than the Momentum True Wireless 4 while retaining enough control to prevent excessive resonance. Both models supply satisfying bass, but the Momentum True Wireless 5 sounds fuller and more engrossing. It provides a clearer upgrade for electronic music, hip-hop, and any genre that benefits from stronger foundational weight.
Mids
The Momentum True Wireless 4 presents a clean and balanced midrange. Instruments and vocals sit naturally within the mix, while notes exhibit a defined attack and satisfying shape. Raising the 1kHz and 4kHz regions through the app can give vocals more emphasis and realism. On the Momentum True Wireless 5, the low mids have a warmer and more dominant presence. This coloration complements its thicker bass response without becoming bloated. Plucks and percussive hits receive some refinement, although they do not always cut through the mix with significant force. The Momentum True Wireless 5 remains clear and cohesive, but its midrange is not especially resolving. Listeners who prefer a warmer, smoother presentation may favor it, while those who want more natural vocal placement and note definition might prefer the Momentum True Wireless 4.
Highs
The Momentum True Wireless 4 offers a crisp and immediately noticeable treble response. Its highs add snap and edge to the overall tuning while remaining smooth enough to avoid harsh peaks. There is also a slight sense of height that gives the presentation some additional scale. Treble on the Momentum True Wireless 5 is similarly controlled but has a slightly different character. It produces crisp clicks and clearly defined cymbal strikes without introducing fatigue. The response is not especially airy, yet its natural timbre and subtle sparkle keep it engaging. A noticeable roll-off prevents the highs from becoming overly sharp. The Momentum True Wireless 4 sounds a little more energetic in this region, while the Momentum True Wireless 5 prioritizes control and cohesion. The better choice will depend on whether you prefer extra bite or a smoother finish.
Summary
The Momentum True Wireless 5 is the more complete flagship earbud. Its slimmer housing provides a more secure and comfortable fit, while stronger ANC, Bluetooth 6.0, extended case capacity, and replaceable batteries improve the everyday experience. Its sound also carries greater bass depth and a more layered sense of space. That does not make the Momentum True Wireless 4 obsolete. It still offers accurate imaging, aptX Lossless, Auracast, responsive app controls, and a clean sound signature. Its midrange can even feel more naturally balanced, making it a strong value if available at a meaningful discount.
Existing Momentum True Wireless 4 owners do not necessarily need to upgrade for sound quality alone. The fifth-generation model makes the most sense if you want better comfort, isolation, battery longevity, or a more powerful low end. New buyers seeking the best overall Sennheiser true wireless experience should choose the Momentum True Wireless 5, while value-conscious listeners can still find plenty to enjoy in the Momentum True Wireless 4.
The Sennheiser Momentum True Wireless 4 and 5 are available at Audio46.
