The current Sennheiser MOMENTUM 4 Wireless Headphone is the epitome of Sennheiser’s craftsmanship and innovation with great sound quality, sleek design, and a bunch of new bells and whistles thrown into the mix. This review will detail the specifics of why the MOMENTUM 4 is a solid pick for both the music enthusiast and the casual listener.

Design and Build Quality

    MOMENTUM 4 Wireless boasts this sleek and minimalistic look, as the premium materials that guarantee durability and comfort are used. These earcups have memory foam padding and wrap in soft leatherette for long-lasting comfort, even in extended listening sessions. The adjustable headband is reinforced with stainless steel to ensure a secure but comfortable fit.

    I'd also point out the absence of a lot of metal parts and, instead, some sort of rubberized coating on the back of the headband. While these features in general create expectations of durability in normal wired headphones, their absence should not insinuate less durability here. As a matter of fact, everything is still pretty well-built. However, I do think the Momentum 4s lifespan will be more related to how long the battery lasts over the wear and tear on the structural components. 

Sound Quality

    With Sennheiser, uncompromised sound quality has always been a priority; the MOMENTUM 4 Wireless headphones are no different. Equipped with 42mm transducers, these headphones let out a well-balanced sound profile: deep bass response, prominent mids, and crystal-clear highs. The soundstage is wide and great for different genres of music. From classical and jazz to hip-hop, the MOMENTUM 4 Headphones automatically adjust for an immersive audio experience.

    The Momentum 4s sound good via Bluetooth, but they're really at their best when hardwired via USB. In some quick tests with the high-resolution (Max) tracks in Tidal, I thought the Bluetooth audio sounds good, but it's no better than my $60 Soundcore true wireless earbuds. That's not surprising-the Bluetooth codec is a limiting factor for both sets of headphones.

Active Noise Cancellation (ANC)

    The MOMENTUM 4 Wireless boasts advanced ANC technology, ensuring that it reduces ambient noise to an absolute minimum. One can therefore hear his or her music or call without much disturbance. Adjusting the ANC through the Sennheiser Smart Control application is possible according to one's environment.

Battery Life

    Among other great features of the MOMENTUM 4 Wireless, one outstanding thing is the battery life: it has a single charge that gives up to 60 hours of playback time. This makes these headphones good for long trips or for longer hearing sessions. The fast charging capability provides hours of playtime on top with just a 10-minute charge.

    In our lab tests, we subjected the Sennheiser MOMENTUM 4 Wireless to a standardized battery endurance test: playing music continuously, peaking at 75dB(SPL). The headphones managed an impressive 56 hours and 21 minutes with ANC enabled. This might outpace actual battery life, considering real-life usage would be variable for everyone.

Connectivity and Controls

The MOMENTUM 4 Wireless has other connectivity options, including a Bluetooth 5. 2 connectivity to make the connection to be smooth and stable as much as possible. Moreover, the product is compatible with most codecs for audio streaming in high quality like AAC, aptX™, and aptX™ Adaptive. The headphones have touch controls on the side of the earpads, allowing you to play, pause, control volumes, and answer/end phone calls using gestures.

The Sennheiser MOMENTUM 4 has great control options.The right earcup contains a single button and an active touch-sensitive surface that's intuitive to use. There's also a signature pinching gesture to toggle between the strength of the ANC and transparency modes, but this requires turning off adaptive ANC in the app. For the most part, the touch surface is responsive, but it can be ever so slightly oversensitive, picking up sometimes unwanted commands if you shift the headphones on your head. Audible beeps confirm when a command is recognized; voice prompts signal Bluetooth connections. Volume changes and track-skipping use the same beep tone, though, which can get confusing. Some other features require the app to be activated as well.

Sennheiser Smart Control App

    Further enriching the user experience, the Sennheiser Smart Control app offers customized sound settings, an equalizer, ANC settings, and firmware updates to keep your headphones updated with all the latest features and enhancements.

    Sennheiser Smart Control app is your useful, clean, easy-to-use keys to EQ tweaks and presets, including the option for the company to run a ‘Sound Check,’ which is determined by listening to your favorite music to set custom presets inclusive of ANC, and a slider that balances how much noise you wish to cancel, all the way up to Transparency, which lets sound in, making you aware of traffic or something.

Comfort and Portability

    Designed for comfort, the MOMENTUM 4 Wireless is lightweight and ergonomically designed. This would give extended listening sessions. The earcups swivel flat for effortless storage. Moreover, the headphones will come with a premium carrying case that adds extra protection when users are on the move.

    Generally, these headphones are lightweight and comfortable, with the headband providing a perfect fit without feeling too tight or too loose.They do not press too hard on the head, and hence, they are not fatiguing to listen with for long periods. However, depending on your ear size, you may find they touch the driver's housing inside the ear cup, and thus you may question comfort in them. Also, people with big heads may have some problem getting a nice fit since the headband will be applying minor pressure to the top of the head. By contrast, though, it's less fatiguing on the ear than the Sony WH-1000XM5 Wireless. 

Price and Availability

    The Sennheiser MOMENTUM 4 Wireless is a premium product and comes tagged at 350$. Yes, it may fall into the higher bracket of the market, but this is well worth your money if you are a serious listener who would not make compromises with the quality of sound for comfort and advanced features.

Is The Sennheiser MOMENTUM 4 Wireless Worth Buying?

    Sennheiser's MOMENTUM 4 Wireless Headphone is the perfect choice for those who would not compromise with quality, innovative features, and long-wearing comfort. Be it exhaustive travel or just pure musical pleasure, these headphones ensure nothing but the very best user experience. With up to an incredible 60-hour battery life, adaptive ANC, and advanced sound tailoring, MOMENTUM 4 Wireless firmly positions itself among the top-rated wireless headphones on the market today.
