Sennheiser Momentum True Wireless 4 Review

Sennheiser Momentum True Wireless 4: Refining a Masterpiece

In the hyper-competitive world of true wireless earbuds, the Sennheiser Momentum line has long been a benchmark for audio purists. It’s the series you recommend to the friend who scoffs at compressed audio and talks about “soundstage.” With the Momentum True Wireless 4 (MTW4), Sennheiser isn’t rewriting the rulebook; it’s meticulously editing it for a new generation of wireless technology. This is less a revolution and more a statement of intent, packing future-proof features into a familiar, premium package. But in a market saturated with excellence, is refinement enough?

Design and Comfort: If It Ain’t Broke…

Unboxing the MTW4 feels reassuringly familiar. The beautiful, fabric-swathed charging case returns, exuding a sense of quality that plastic rivals can’t match. The earbuds themselves retain the chunky, squared-off design of their predecessors, now with metallic accents that catch the light beautifully. While undeniably premium, they remain on the larger side. Those with smaller ears might find the fit a bit intrusive over long periods, despite the inclusion of multiple ear tip sizes and new fin designs to improve stability. The build quality, however, is impeccable. These feel dense, durable, and built to last, justifying their premium standing from the moment you handle them.

Performance: The Sound of the Future

This is where the magic happens. Sennheiser’s “audiophile” reputation is on full display here. The sound signature is exquisitely balanced, delivering deep, textured bass that never bleeds into the mids, and crystal-clear highs that sparkle without a hint of harshness. Vocals and instruments are rendered with stunning detail and separation, creating an expansive soundstage that’s rare in the true wireless format.

What truly sets the MTW4 apart, however, is its forward-looking hardware. Powered by Qualcomm’s S5 Sound Gen 2 platform and Bluetooth 5.4, these earbuds are ready for what’s next. Support for aptX Lossless means that, with a compatible source, you can achieve true CD-quality wireless audio—a claim that finally feels realized here. More importantly, the inclusion of Auracast and LE Audio compatibility makes the MTW4 a genuinely future-proof investment. While Auracast—which allows you to tune into public audio broadcasts in places like airports and museums—is still in its infancy, owning a device that’s ready for this paradigm shift in public listening is a major selling point for any tech enthusiast.

Features: Smart, Not Aggressive

Sennheiser has improved its Adaptive Noise Cancellation, and it’s certainly effective. The MTW4 does an admirable job of hushing low-frequency drones on commutes and office chatter. However, it still doesn’t achieve the near-total silence offered by class-leaders like the Sony WF-1000XM5 or Bose QuietComfort Ultra Earbuds. Sennheiser’s approach feels more natural, reducing ambient noise without creating that pressurized “vacuum” sensation, which some users will prefer. The transparency mode is excellent, letting in the outside world clearly and without artificial processing.

Battery life is solid, clocking in at around 7.5 hours on a single charge with ANC off, with the case providing roughly three additional charges. Connectivity is flawless, with rock-solid pairing and reliable multipoint support for switching between two devices seamlessly. Sennheiser’s Smart Control app remains one of the best, offering deep customization, including a “Sound Personalization” feature that genuinely helps tailor the EQ to your specific hearing profile.

The Verdict

The Sennheiser Momentum True Wireless 4 are not a dramatic reinvention, but a powerful and intelligent evolution. They are built for the discerning listener who prioritizes audio fidelity and technological longevity above all else. While the noise cancellation isn’t the absolute strongest on the market and the bulky design won’t be for everyone, their sonic performance is simply magnificent. For the audiophile who wants to experience the bleeding edge of wireless audio with aptX Lossless and be prepared for the connected world of Auracast, the MTW4 are not just an excellent choice—they are arguably the most complete and forward-thinking package available today.
