Apple AirPods Max 2 vs Sennheiser MOMENTUM 4: ANC and battery life duke it out
The Apple AirPods Max 2 and Sennheiser MOMENTUM 4 Wireless top our best ANC headphones list for good reason. Apple leans heavily into ecosystem integration, software convenience, and premium materials, while Sennheiser focuses more on practical comfort, battery life, and broad codec support. Apple’s latest model improve on the original with the company’s H2 chip and better ANC, but they’re an iterative update with familiar compromises. Meanwhile, the MOMENTUM 4 Wireless may not match Apple’s ecosystem polish, but they offer a more balanced package at a lower price. Here’s how they stack up in 2026.
What’s it like to use the Apple AirPods Max 2 compared to the Sennheiser MOMENTUM 4?
Deep pads and earcups provide a natural advantage for all headphone users.
Using the Apple AirPods Max 2 is a premium experience, largely thanks to their aluminum ear cups, metal frame, and mesh canopy headband. The deep ear cups and magnetic cushions are comfortable, the digital crown is intuitive, and head gestures add convenience during calls. However, at 386g, the cans are undeniably heavy. Likewise, the strong clamping force can become fatiguing over long listening sessions, particularly for those with larger-than-average heads. Apple also continues with the same awkward Smart Case and lack of a dedicated power button that plagued the original AirPods Max.
By comparison, I find the Sennheiser MOMENTUM 4 Wireless more practical for daily wear. The plastic construction makes them much lighter, and the padding accommodates glasses well without causing significant strain. While over-tightening can create pressure on the top of the head, overall comfort is easier to maintain for long listening sessions. Sennheiser also includes a far more functional carrying case with useful storage, plus a physical power button (it’s really not that hard, Apple).
For controls, Apple uses its crown and dedicated mode button effectively, while Sennheiser relies on touch gestures plus a multifunction hardware button. In my experience, both are usable, but Sennheiser’s inclusion of standard power controls gives it an advantage for straightforward daily use.
Do the Apple AirPods Max 2 or Sennheiser MOMENTUM 4 have more features?
Real-time language translation is now available on the Apple AirPods Max 2.
Apple’s H2 chip unlocks a wide range of software features for iPhone, iPad, and Mac users. Live Translation is a favorite for frequent travellers, while the headphones also support Personalized Volume, Loud Sound Reduction, Conversation Awareness, Personalized Spatial Audio, and automatic device switching. In my testing, Personalized Volume and Conversation Awareness are genuinely useful, though Live Translation still suffers from noticeable latency, making conversations awkward. As with all Apple products, the biggest drawback is that nearly all of these advanced features are locked behind its ecosystem, and there’s still no custom EQ.
Sennheiser’s Smart Control app offers a different kind of value. Rather than Apple’s ecosystem exclusives, it gives users granular control over ANC intensity, Adaptive ANC, geotagging, Smart Pause, firmware updates, and EQ options. I appreciate that Sennheiser gives listeners far more freedom to tailor the headphones to their preferences, especially with sound customization. While some features require data permissions, the flexibility is impressive.
Apple clearly wins overall for iOS fans, but Sennheiser offers broader customization and platform neutrality. If you value control over your listening experience, Sennheiser’s software suite feels more versatile.
How do the Apple AirPods Max 2 and Sennheiser MOMENTUM 4 connect?
The Sennheiser Momentum 4 Wireless has more Bluetooth codec options.
The Apple AirPods Max 2 use Bluetooth 5.3 with the SBC and AAC codecs. Apple’s wireless pairing and automatic device switching work extremely well within its ecosystem, and I found connections stable and seamless. USB-C wired playback also enables lossless audio, though settings adjustments remain unavailable when wired. Similarly, while the headphones support Multipoint, it only works with compatible Apple devices. As with the previous generation, the AirPods Max 2 do not support Auracast, LE Audio, or LC3.
The Sennheiser MOMENTUM 4 Wireless offer broader connectivity with Bluetooth plus wired USB-C and 3.5mm options. Codec support includes SBC, AAC, aptX, aptX HD, and aptX Adaptive, giving Android users and codec-conscious listeners far more flexibility. In my experience, this makes Sennheiser considerably more adaptable across different devices and platforms. If you want simplicity and own an iPhone, go with Apple. Otherwise, the MOMENTUM 4 provide superior codec and connection variety.
Is battery life better on the Apple AirPods Max 2 or the Sennheiser MOMENTUM 4?
The H2 chip brings many features from the AirPods Pro 3 to Apple’s newest over-ears.
Battery life is one of the clearest divides here. Apple rates the AirPods Max 2 for up to 20 hours with ANC, which feels underwhelming for a flagship in 2026. While that’s enough for a couple of days, I would need to recharge them much more frequently than competitors. It also means the headphones will have a shorter shelf life, which is worse for the environment.
Sennheiser dominates here with 56 hours and 21 minutes in our standardized battery tests. That result is exceptional, and in practical use, it dramatically reduces charging frequency. I also appreciate the physical power switch, even if Auto On/Off can occasionally misfire. For endurance alone, the MOMENTUM 4 Wireless are in another league.
Do the Apple AirPods Max 2 or Sennheiser MOMENTUM 4 block noise better?
There’s no competition here — Apple’s AirPods Max 2 offer much stronger ANC. The perceived loudness of outside sounds is reduced by about 89.4%, and the headphones offer improved attenuation over the original model, especially in the mids. In my office testing, chatty coworkers and environmental hum were effectively dulled. Transparency Mode also sounds remarkably natural, and Adaptive Mode is genuinely useful during commutes.
The Sennheiser MOMENTUM 4 Wireless perform well, reducing high-pitched noise by roughly 75-95% and lower-pitched sounds by around 75%. However, this performance significantly lags behind more up-to-date category leaders. They’re still effective for commuting and office use, but Apple’s latest model clearly have the edge.
Do the Apple AirPods Max 2 sound better than the Sennheiser MOMENTUM 4?
Capacitive touch controls allow quick inputs like call controls and music playback options.
Both headphones sound good, and most people should enjoy them out of the box. The Apple AirPods Max 2 emphasize the sub-bass and treble, adding extra “oomph” and clarity to tracks. There’s a significant dip between 3kHz and 6kHz, but vocals and synths are audible. In practical use, the inability to adjust the tuning with a custom EQ remains frustrating. Similarly, I found the Loudness-Dependent Equalization (LDEQ) feature can become fatiguing at lower volumes, reproducing far too much bass and treble for most listeners.
Objective Measurements
As you can see, the Sennheiser MOMENTUM 4 Wireless offer more natural tuning in the high-end out of the box. Their frequency response stays close to SoundGuys’ preference curve, with slightly elevated bass below 100Hz. In my listening, Sennheiser’s tuning feels more balanced and easier to enjoy across genres, and the app’s EQ options make refinement simple.
How do the Apple AirPods Max 2 sound with LDEQ enabled?

As stated earlier, reducing the AirPods Max 2’s volume to 50% significantly boosts the bass and treble. If you reduce the volume even further, you can expect the bass and treble to increase even more. So, the AirPods Max 2 become increasingly fatiguing as you decrease the volume.
Do the Apple AirPods Max 2 sound different with ANC off?
[adp_audio model_id=”538″ measure_id=”185″ style=”comparison” comparison_model_id=”538″ comparison_measurement_id=”406″ target_id=”1″ alt=”A chart comparing the Apple AirPods Max 2’s tested ANC off frequency response to Apple AirPods Max 2 Default, as compared to the SoundGuys Headphone Preference Curve.” limit=”false” /]
Yes, the AirPods Max 2 introduce noise below 100Hz when ANC is switched off. They also suffer crosstalk at these frequencies, so something is clearly behaving oddly when ANC is disabled. Most listeners shouldn’t notice this in real-world listening environments, but it’s an odd result nonetheless.
How would most people rate the sound from 1 to 5?
TKTK
What do the Multi-Dimensional Audio Quality Scores mean?
- Timbre (MOS-T) represents how faithfully the headphones reproduce the frequency spectrum and temporal resolution (timing information).
- Distortion (MOS-D) represents non-linearities and added noise: higher scores mean cleaner reproduction.
- Immersiveness (MOS-I) represents perceived source width and positioning: how well virtual sound sources are defined in three-dimensional space.
From an MDAQS perspective, Apple receives a “good” score overall. However, their lower Timbre score means the headphones struggle to reproduce songs faithfully compared to other headphones on the market. Likewise, some listeners may find it harder to place instruments around them in a three-dimensional space.
TKTK
Sennheiser posts excellent Timbre and strong spatial performance, making the MOMENTUM 4 especially compelling for musos. However, their Distortion score indicates that some listeners may hear added noise when listening to their favorite tracks. Overall, I find Sennheiser’s natural presentation more consistently enjoyable, but the AirPods Max 2 also offer decent sound quality.
Do the Apple AirPods Max 2 or the Sennheiser MOMENTUM 4 have a better microphone?
The AirPods Max 2’s Voice Isolation mode significantly improves call quality.
The Apple AirPods Max 2 offer mixed microphone performance by default. Standard mode struggles with noise rejection, meaning windy, busy, or reverberant environments can make it more difficult for callers to hear you on the other end of the line. Voice Isolation mode sounds better, but more on that in a moment.

The Sennheiser MOMENTUM 4 Wireless perform well for calls, but they also struggle with noise rejection. Overall, neither headset fully escapes the common constraints of built-in headphone microphones. However, Apple’s Voice Isolation feature gives it a stronger edge when manually enabled (take a listen below).
