The Sennheiser MOMENTUM 4 Wireless Headphone represents the pinnacle of Sennheiser's audio engineering, combining premium sound quality, modern design, and advanced features. This review delves into the details of what makes the MOMENTUM 4 a standout choice for audiophiles and casual listeners alike.

Design and Build Quality

    The MOMENTUM 4 Wireless offers a sleek and minimalist design, characterized by premium materials that ensure durability and comfort. The ear cups are cushioned with memory foam, wrapped in soft leatherette, providing long-lasting comfort for extended listening sessions. The headband is adjustable and reinforced with stainless steel, offering a secure fit without compromising on comfort.

    I want to point out the absence of metal components and the use of a rubberized coating on the underside of the headband. While these elements are typically indicators of longevity in traditional wired headphones, their absence here doesn't necessarily imply reduced durability. In fact, the overall build quality remains robust. However, I anticipate that the lifespan of the Momentum 4s will likely be determined more by the battery's longevity rather than any wear and tear on the structural components.

Sound Quality

    Sennheiser is renowned for its superior sound quality, and the MOMENTUM 4 Wireless is no exception. Equipped with 42mm transducers, these headphones deliver a balanced sound profile with deep bass, rich mids, and clear highs. The soundstage is expansive, making it ideal for various genres of music. Whether you're listening to classical, jazz, or hip-hop, the MOMENTUM 4 adapts to provide an immersive audio experience.

    The Momentum 4s deliver solid sound quality over Bluetooth, but they truly excel when connected via USB. During quick tests with high-resolution (Max) tracks on Tidal, I found that while the Bluetooth audio quality is good, it’s comparable to that of my $60 Soundcore true wireless earbuds. This similarity is expected, given that the Bluetooth codec is a limiting factor for both sets of headphones.

Active Noise Cancellation (ANC)

    The MOMENTUM 4 Wireless features advanced Active Noise Cancellation (ANC) technology, which effectively reduces ambient noise, allowing you to focus on your music or calls without distractions. The ANC can be adjusted through the Sennheiser Smart Control app, giving you control over the level of noise cancellation based on your environment.

Battery Life

    One of the standout features of the MOMENTUM 4 Wireless is its impressive battery life. With up to 60 hours of playback time on a single charge, these headphones are perfect for long trips or extended listening sessions. Additionally, the fast charging capability provides several hours of playback with just a 10-minute charge.

    In our lab tests, we put the Sennheiser MOMENTUM 4 Wireless through a standardized battery endurance test, playing continuous music at a peak volume of 75dB(SPL). The headphones achieved an impressive 56 hours and 21 minutes of playback with ANC enabled. While actual battery life can vary based on individual usage, this performance significantly outpaces that of competing ANC headphones, as illustrated below:

Connectivity and Controls

    The MOMENTUM 4 Wireless offers seamless connectivity through Bluetooth 5.2, ensuring a stable connection with your devices. It supports multiple codecs, including AAC, aptX™, and aptX™ Adaptive, for high-quality audio streaming. The headphones also feature intuitive touch controls on the ear cups, allowing you to manage playback, volume, and calls with simple gestures.

    The Sennheiser MOMENTUM 4 offers excellent control options. The right ear cup features a single button and a responsive touch-sensitive surface that's intuitive to use. A distinctive pinching gesture allows you to adjust the strength of the ANC and transparency modes, though this function requires adaptive ANC to be disabled in the app. While the touch surface is generally responsive, it can be overly sensitive, sometimes registering unintended commands if the headphones are adjusted on your head. Audible beeps confirm when a command is recognized, with voice prompts signaling Bluetooth connections. However, the beeps for volume changes and track-skipping share the same tone, which can be confusing. Additionally, certain features require the app to be activated.

Sennheiser Smart Control App

    The Sennheiser Smart Control app enhances the user experience by providing customizable sound settings. The app includes an equalizer, ANC adjustments, and firmware updates, ensuring that your headphones are always up-to-date with the latest features and improvements.

Comfort and Portability

    Designed for comfort, the MOMENTUM 4 Wireless is lightweight and ergonomically designed for long listening sessions. The ear cups swivel flat for easy storage, and the headphones come with a premium carrying case for added protection while on the go.

    These headphones are generally lightweight and comfortable for most users, with a headband that offers a snug yet comfortable fit. They don't exert excessive pressure on the head, making them suitable for long listening sessions. However, if you have larger ears, you might find that they make contact with the driver housing inside the ear cups, which could affect comfort. Additionally, those with larger heads might struggle to achieve an optimal fit, as the headband can apply slight pressure on the top of the head. Despite this, the pressure is less fatiguing compared to the Sony WH-1000XM5 Wireless.

Price and Availability

    The Sennheiser MOMENTUM 4 Wireless is positioned as a premium product, with a price tag of 350$. While it may be on the higher end of the market, the combination of sound quality, comfort, and advanced features makes it a worthwhile investment for serious listeners.

Is The Sennheiser MOMENTUM 4 Wireless Worth Buying?

Whether you're a frequent traveler, a music enthusiast, or someone who simply appreciates high-quality audio, these headphones deliver on all fronts. With an impressive 60-hour battery life, adaptive ANC, and customizable sound settings, the MOMENTUM 4 Wireless stands out as one of the best wireless headphones available today.
