This is a duel between two very different priorities. The Sennheiser Momentum 4 Wireless is built for the long haul — marathon battery life, wired backup options, and sound quality reviewers routinely rank above the competition. The Bose QuietComfort Ultra is built for silence — class-leading noise cancellation and a personalized listening experience via CustomTune and Immersive Audio.
If you're choosing between these two, the decision usually comes down to one question: do you value uninterrupted playback and flexibility, or the deepest possible noise-blocking bubble? Here's how they actually compare.

Pros & Cons
Pros — Sennheiser Momentum 4 Wireless
- Class-leading battery life, independently tested at over 56 hours with ANC on
- Sound quality widely praised, with reviewers ranking it ahead of Bose and Sony rivals
- Wired listening supported via both USB-C and 3.5mm analog cable
- Feature-rich Smart Control app with full EQ, Sound Zones, and Sound Personalization
- Lightweight, comfortable, foldable design for long sessions
Cons
- ANC trails top-tier rivals like Bose and Sony

- Stock tuning can run bass-heavy or slightly harsh in the treble before EQ adjustment
- Relies more on touch controls and the app, with fewer physical buttons
Pros — Bose QuietComfort Ultra Headphones
- Some of the best active noise cancellation on the market, cutting environmental noise by an average of 85% in lab testing
- Exceptional comfort with soft cushioning and even pressure for long wear
- Premium, sleek metal-accented design
- Immersive Audio spatial sound plus CustomTune personalization tailored to ear shape
- Strong call quality from its noise-rejecting microphone array
Cons
- Shorter battery life than the Momentum 4, especially with Immersive Audio enabled
- Bose Music app offers only limited EQ compared to Sennheiser's app
- Original model lacked wired USB-C listening, fixed only in the 2nd Gen version
- Sits at a premium price point relative to competitors offering similar core features
- Out-of-the-box sound can be bass-heavy until EQ adjustments are made
Battery Life & Everyday Flexibility
This isn't close. The Momentum 4 is tested at over 56 hours with ANC on, more than double what the QuietComfort Ultra offers even in its improved 2nd Gen form (30 hours). Sennheiser also backs this with fast charging that adds 4-6 hours of playback from just 5 minutes on the charger, and it's the only one of the two with a true wired fallback via USB-C in addition to the analog jack. For anyone who travels often or hates babysitting a charge cycle, the Momentum 4 is the clear pick.
Noise Cancellation & Personalization
Bose's reputation here is earned. The QuietComfort Ultra was measured cutting environmental noise by an average of 85% in lab testing, and its Immersion Mode layering ANC with Immersive Audio is a feature Sennheiser has no answer for. CustomTune's ear-shape analysis adds a layer of personalized tuning the Momentum 4's app-based EQ can't replicate. If blocking out the world is the priority, Bose wins this category outright — and reviewers note the Momentum 4's ANC, while solid, trails both Bose and Sony.
Sound Quality & Software
Reviewers consistently rank the Momentum 4's sound ahead of the competition, including Bose, thanks to its 42mm audiophile-inspired driver and wide 6 Hz-22 kHz frequency response. Sennheiser's Smart Control app also goes deeper, offering full EQ, Sound Zones, and Sound Personalization, compared to the comparatively basic Bose Music app with its limited EQ. Both headphones ship with bass-heavy stock tuning that benefits from EQ adjustment, but Sennheiser gives you more tools to fix it.
Comfort, Design & Value
Both are praised for comfort — Sennheiser's lightweight, foldable design versus Bose's soft cushioning and even pressure distribution built for long sessions. Bose leans into a premium metal-accented look and premium pricing to match, while the Momentum 4 sits at a mid-range price and undercuts Bose while offering more included accessories and longer usable life per charge. For buyers weighing cost against features, Sennheiser delivers more for less.
The Sennheiser Momentum 4 Wireless takes this duel for most listeners. It offers dramatically longer battery life, better-reviewed sound quality, a deeper feature set in its companion app, wired flexibility, and a mid-range price — a stronger overall package for everyday use. The Bose QuietComfort Ultra remains the choice for one specific priority: if the single most important factor is the strongest possible noise cancellation and an immersive, personalized listening bubble, and price is no object, Bose still leads there. For everyone else, Sennheiser is the smarter buy.
