Sennheiser has refined its flagship true wireless earbuds with the MOMENTUM True Wireless 4, focusing on audio quality, future-ready wireless technology, and improved reliability rather than a complete redesign. While the earbuds look familiar to their predecessor, they introduce meaningful upgrades such as Bluetooth 5.4, aptX Lossless, LE Audio readiness, and enhanced adaptive active noise cancellation (ANC).
Priced in the premium segment, the MOMENTUM True Wireless 4 competes directly with the Sony WF-1000XM5, Bose QuietComfort Ultra Earbuds, and Apple AirPods Pro (2nd generation).
Design and Comfort
At first glance, the MOMENTUM True Wireless 4 looks nearly identical to the previous model. The earbuds retain Sennheiser’s signature fabric-covered charging case and ergonomic design.
Highlights include:
- Comfortable in-ear fit with multiple ear tip sizes
- IP54 dust and splash resistance
- Premium fabric-covered USB-C charging case
- Wireless charging support
Despite being slightly larger than some competitors, the earbuds remain comfortable for extended listening sessions.
Audio Quality: The Biggest Strength
Sound quality is where the MOMENTUM True Wireless 4 truly shines.
The earbuds feature Sennheiser’s 7mm TrueResponse dynamic drivers, delivering a rich and balanced sound signature with:
- Deep, controlled bass
- Clear and natural vocals
- Detailed mids
- Crisp, well-extended treble
- Wide soundstage
The companion Smart Control app offers customizable EQ settings, Sound Personalization, and presets, allowing users to tailor the audio experience to their preferences. Reviewers consistently praise the earbuds for offering some of the best sound quality in the premium true wireless category.
Future-Ready Connectivity
One of the standout upgrades is the inclusion of Qualcomm’s latest wireless technologies.
Connectivity features include:
- Bluetooth 5.4
- Snapdragon Sound
- aptX Adaptive
- aptX Lossless
- AAC and SBC codec support
- Bluetooth LE Audio readiness
- Auracast support (via firmware update)
- Multipoint connectivity
These additions make the earbuds particularly appealing to Android users seeking high-resolution wireless audio.
Active Noise Cancellation
Sennheiser has improved the adaptive ANC system, which effectively reduces everyday ambient noise such as office chatter, traffic, and airplane cabin noise.
Transparency Mode also allows outside sounds to pass through naturally when needed.
While the ANC performance is noticeably better than previous generations, reviewers generally agree that Sony and Bose still hold a slight edge in maximum noise cancellation.
Battery Life
Battery performance remains one of the earbuds’ strengths.
Sennheiser claims:
- Up to 7.5 hours of playback on a single charge (without ANC)
- Up to 30 hours with the charging case
- Fast charging support
- Qi wireless charging
This makes the MOMENTUM True Wireless 4 suitable for long commutes, travel, and extended listening sessions.
Call Quality and Smart Features
The earbuds include multiple microphones with AI-assisted noise reduction to improve voice clarity during calls.
Additional features include:
- Customizable touch controls
- Wear detection
- Google Fast Pair
- Smart Pause
- Companion Smart Control app
- Firmware updates via the app
Call quality is solid for everyday use, though some reviewers note that rivals perform slightly better in particularly noisy environments.
