Final Verdict
The Momentum 4 is the best over-ear headphone for buyers who prioritize endurance and sound fidelity over raw ANC depth. It outperforms both Sony and Bose on battery life by a factor of two while delivering sound that audiophile communities consistently prefer. Instead of matching their ANC benchmarks, it doubles their battery and undercuts their price while delivering sound quality that audiophile communities prefer. The compromises — weaker ANC in extreme noise, less polished software, warmer-running cushions — are real and documented. But for the buyer who values endurance, sound fidelity, and value, the Momentum 4 is the most rational purchase in the category. For the full head-to-head, read our Momentum 4 vs Sony WH-1000XM5 comparison and our best over-ear ANC headphones roundup.
Overview
Sixty hours. That is the number that defines the Sennheiser Momentum 4 and separates it from every competitor in the premium ANC category. While Sony and Bose deliver 30 hours and Apple manages 20, Sennheiser doubled the field. The Momentum 4 is the headphone you charge on Sunday and forget about until the following weekend.
TechRadar awarded 5 stars and declared it "better than the Sony WH-1000XM5" as an overall package. Head-Fi audiophile reviewers praise its sound signature as "among the most natural in the ANC category." SoundGuys described it as "warm but detailed — gently elevated bass with slightly relaxed treble" — a tuning that avoids listening fatigue across marathon sessions that the battery enables. At $247, it undercuts both the $398 Sony WH-1000XM6 and the $359 Bose QC Ultra while offering something neither can match: the confidence that your headphones will outlast any trip, any workday, any session you throw at them.
The compromise is ANC. In quiet offices, cafes, and commuter trains, the Momentum 4's three-level ANC performs well. In aircraft cabins, loud subways, and construction-adjacent environments, the gap between Sennheiser and the Sony/Bose tier becomes audible. RTINGS confirms the difference is most pronounced in high-frequency isolation — air conditioning hum, PA announcements, and high-pitched engine noise get through more than on the XM6 or QC Ultra. If you need silence above all else, the Momentum 4 is not your headphone. If you need a headphone that sounds great, lasts forever, and cancels most noise in most situations, it belongs on your shortlist.
Key Specifications
What Makes the Momentum 4 Different
The 60-Hour Battery: What It Means in Practice
Real-world testing confirms 57-59 hours with ANC on — close enough to Sennheiser's claim that the difference is rounding. Under heavy daily use at 5-6 hours per day, a full charge lasts roughly 10 days. Under moderate daily use at 3-4 hours, you charge every two weeks. The 10-minute quick charge adds 6 hours — enough for a full workday from a coffee-break charge.
The practical implication extends beyond convenience. For multi-day business trips, the Momentum 4 is the headphone you do not pack a charger for. A 3-day trip with 8-10 hours of daily use (flights, hotel, meetings) consumes roughly half the battery. A week-long trip with moderate use still fits within a single charge. The Sony WH-1000XM6 at 30 hours needs a mid-trip charge on the same itinerary; the Bose QC Ultra matches Sony at 30 hours. Battery anxiety disappears with the Momentum 4 in a way that no competitor can replicate at any price.
42mm Driver and the Audiophile Sound
The Momentum 4's 42mm driver — larger than the Sony XM5 (30mm) and XM6 (40mm) — produces what Head-Fi reviewers consistently describe as the most natural sound in the ANC headphone category. "Natural" here means: instruments sound like instruments, vocals sit where a sound engineer placed them, and the frequency response avoids the aggressive processing that characterizes Sony's V-shaped tuning and Bose's bass-forward signature.
The bass is gently elevated — present and warm without overwhelming the midrange. Treble is slightly relaxed — detailed without sibilance or harshness at high volumes. SoundGuys confirmed this tuning is "non-fatiguing during long sessions," which matters more when your battery lasts 60 hours than when it runs dry at 30. For critical listening — jazz, classical, live recordings, acoustic singer-songwriter material — the Momentum 4 reveals more natural texture and spatial information than either the Sony or Bose. For bass-heavy genres where impact and punch matter more than accuracy, the Sony XM6 or Bose QC Ultra deliver more excitement.
aptX Adaptive: The Android Codec Advantage
Android users face a codec choice between Sony's LDAC and Sennheiser's aptX Adaptive — and the comparison is closer than the marketing suggests. Both codecs target high-res wireless audio. LDAC peaks at 990 kbps; aptX Adaptive dynamically adjusts between 279 and 420 kbps while maintaining lower latency. In blind A/B testing documented on Head-Fi, most listeners cannot reliably distinguish between the two at their highest quality settings. The Momentum 4's aptX Adaptive advantage: lower latency for video sync (no lip-sync issues), and better connection stability in crowded Bluetooth environments like airports and conference centers. Read our Bluetooth codecs guide for the full technical comparison between LDAC, aptX Adaptive, and AAC.
German Engineering Aesthetic
The Momentum 4 does not look like the flashiest headphone on a shelf — and that is the point. The design is proportional, understated, and built to look professional in a video call or a business meeting. No oversized brand logos. No chrome accents. The matte finish resists fingerprints better than Sony's glossy plastic. The folding mechanism is sturdy and compact, producing a travel case slightly smaller than the XM6's. For buyers who want headphones that communicate competence rather than lifestyle branding, the Sennheiser aesthetic is a deliberate advantage.

Performance & Real-World Testing
Daily Use and ANC Testing
ANC: Strong, Not Best-in-Class
The Momentum 4 offers three ANC levels through the Sennheiser Smart Control app. At maximum, it cancels office conversation, cafe noise, keyboard sounds, and moderate traffic effectively. The isolation is good enough for focused work in an open-plan office and good enough for a commuter train where the dominant noise is the rail rumble.
Where the gap appears: aircraft cabins, subway cars, and environments with sustained low-frequency noise above 80 dB. In these conditions, the Sony XM6's 12-microphone system and the Bose QC Ultra's CustomTune calibration both achieve deeper cancellation that is audible without direct comparison. The Momentum 4 reduces airplane engine noise; the Sony and Bose nearly eliminate it. For frequent flyers who prioritize silence, this gap matters. For desk workers and urban commuters, the Momentum 4's ANC is fully sufficient.
The Firmware Stability Question
Multiple Head-Fi and Reddit threads document firmware-induced issues: Bluetooth dropping during codec negotiation, the Smart Control app failing to maintain EQ settings after updates, and a digital crackling artifact that appears when ANC mode switches automatically. These issues are not universal — they affect a subset of users, often correlated with specific phone models and firmware versions — but they occur frequently enough to mention.
Sennheiser's Smart Control app is functional but lacks the polish and depth of Sony Headphones Connect. It provides basic EQ adjustment, ANC level selection, and transparency mode toggling. It does not offer per-source profiles, auto NC optimization, or the granular frequency-band EQ that Sony provides. For users who install the app once and never reopen it, this is irrelevant. For tinkerers, Sony's app is a league ahead.
Comfort During Long Sessions
At 293g, the Momentum 4 is heavier than the Sony XM6 (254g) and Bose QC Ultra (260g), but lighter than the AirPods Max (392g). The weight distribution across the padded headband is even, and clamping force sits in the moderate range — firm enough to maintain an ANC seal, loose enough to avoid pressure-point headaches during 4-5 hour sessions.
The faux leather ear cushions are deep and oval-shaped, accommodating most ear sizes without contact. The material choice has one compromise: heat retention. In warm offices or during summer use, the synthetic leather traps more warmth than Bose's protein leather cushions. The Bose QC Ultra remains the comfort champion for 6-8 hour sessions, but the Momentum 4 holds its own for the 4-6 hour stretches that represent most real-world use.
Value Analysis
At $247, the Momentum 4 is below average for its category for the over-ear ANC headphone category — $151 below the Sony WH-1000XM6 flagship, $112 below the Bose QC Ultra 2nd gen, and $31 above the discounted Sony WH-1000XM5. At this price, it offers a value proposition that neither Sony nor Bose can match: double the battery, audiophile-approved sound, and aptX Adaptive — all for less than either flagship.
This Is Your Headphone If...
- Battery life is the priority — charging once a week changes how you use headphones
- You prefer a balanced, natural sound signature over the processed tuning of Sony or Bose
- You use an Android phone and want aptX Adaptive for high-res wireless with low latency
- You travel for business and want a headphone that survives multi-day trips without a charger
- Price matters — the Momentum 4 delivers premium sound and features at a mid-range price
Look Elsewhere If...
- ANC depth is your primary concern — the Sony XM6 and Bose QC Ultra both cancel more noise in loud environments
- Call quality in noisy spaces matters daily — the Sony XM6's 12-mic array leads the category
- You need deep app customization — Sony Headphones Connect is substantially more capable than Sennheiser Smart Control
- All-day comfort beyond 6 hours is essential — the Bose QC Ultra cushions are plushier and cooler
What to Expect Over Time
Battery Longevity
The 60-hour battery means fewer charge cycles per year than competitors — roughly 50-70 full cycles annually under heavy use, compared to 120-180 cycles for a 30-hour headphone. Fewer cycles means slower battery degradation. After 2 years, expect 85-90% of original capacity — still over 50 hours with ANC, which exceeds every competitor's brand-new specification. The only wireless headphone with a longer total runtime is the HyperX Cloud Alpha Wireless at 300 hours, a gaming headset without ANC. The lithium-ion cells benefit from the shallower discharge patterns that a larger battery enables: most users never drain below 30% before recharging, which extends cell longevity.
Ear Pad and Build Durability
The faux leather cushions show wear faster than Bose's protein leather — expect visible compression and surface cracking after 12-15 months of daily use. Replacement pads from Sennheiser cost mid-tier pricing, with third-party options available at lower cost. The folding hinge mechanism has no widespread failure reports — Sennheiser's build quality reputation is earned, even if the plastic construction feels less premium than Sony's or Apple's metal accents.
Software Support Outlook
Sennheiser typically supports flagship headphones with firmware updates for 2-3 years. The Momentum 4 launched in August 2022 and has received periodic updates through 2025 — expect another year of active development before the product enters maintenance mode. The Smart Control app will continue to function after updates cease; the headphone's core features do not depend on ongoing software. Compared to Sony (which supported the XM4 for 3+ years with feature additions) and Apple (which delivers silent firmware updates indefinitely), Sennheiser's support window is adequate but not industry-leading.
The Successor Question
Sennheiser has not announced a Momentum 5, but the 3-year product cycle that has defined the Momentum line suggests a successor in late 2025 or early 2026. The Momentum 4's current discounted pricing likely reflects the approach of a next-generation model. For buyers hesitating: the Momentum 4 at $247 is an excellent purchase regardless of a potential successor. The battery life advantage is so large that even an incremental Momentum 5 update (improved ANC, slightly better sound) would not invalidate the 4's value proposition. Pick one up, enjoy the 60-hour battery, and evaluate an upgrade if and when the successor appears. The Momentum 4 at its current price is not a compromise purchase — it is a smart purchase.
Questions About the Sennheiser Momentum 4
How long does the Sennheiser Momentum 4 battery last?
Sennheiser rates it at 60 hours with ANC on — real-world testing consistently confirms 57-59 hours. This is more than double the 30-hour battery life of both the Sony WH-1000XM6 and Bose QC Ultra. Under heavy daily use (5-6 hours per day), you charge approximately once per week. A 10-minute quick charge provides 6 hours of playback.
Is Sennheiser Momentum 4 good for flying?
It is adequate for flights but not the best choice if ANC is your primary concern for air travel. The Momentum 4 ANC cancels office noise and moderate ambient sound effectively, but in loud aircraft cabins, the Sony WH-1000XM6 and Bose QC Ultra both provide noticeably deeper noise isolation at low frequencies. For frequent flyers who prioritize silence, choose Sony or Bose. For occasional travelers who value battery life across a multi-leg trip, the Momentum 4 covers both flights without needing a charge.
Does Sennheiser Momentum 4 support LDAC?
No. The Momentum 4 supports aptX Adaptive, aptX, AAC, and SBC — but not LDAC. For Android users, aptX Adaptive delivers high-quality wireless audio that rivals LDAC in most listening conditions. The two codecs approach high-res wireless from different technical angles; in blind testing, most listeners cannot distinguish between aptX Adaptive and LDAC at their highest bitrates.
Sennheiser Momentum 4 vs Sony WH-1000XM5 — which should I buy?
The Momentum 4 wins on battery life (60 vs 30 hours), sound neutrality (preferred by audiophiles), and codec variety (aptX Adaptive). The Sony XM5 wins on ANC depth (especially in loud environments), call quality (4 beamforming mics), and app customization depth. Choose the Momentum 4 for balanced sound and marathon battery; choose the XM5 for the strongest possible ANC.
Is the Sennheiser Momentum 4 comfortable for all-day wear?
The 293g weight and padded headband make it comfortable for 4-5 hour sessions. The faux leather ear cushions are deep enough for most ear sizes but can trap heat during summer or in warm offices. The clamping force is moderate — less than Sony, more than Bose. For all-day 8+ hour wear, the Bose QC Ultra is more comfortable; for 4-6 hour sessions, the Momentum 4 is on par with the Sony XM6.
