Sennheiser MOMENTUM 4 Wireless Headphones (Denim)

Sennheiser MOMENTUM 4 Wireless Headphones (Denim)

The Sennheiser MOMENTUM 4 Wireless in Denim is an over-ear Bluetooth headphone built for long listening: up to 60 hours of battery life with noise cancellation active, adaptive noise cancelling, a 42-millimetre dynamic driver and a fold-flat design made for travel and daily commuting. The Denim finish gives this version its blue, fabric-inspired colourway, distinguishing it from the standard Black and White versions while the acoustic and electronic specification remains the MOMENTUM 4 platform. Sennheiser redesigned the MOMENTUM line with this generation around comfort, endurance and simpler controls, replacing physical buttons for most functions with touch gestures on the earcup and adding automatic power and pause behaviour so the headphones respond when they are picked up, worn and set down.

Key features

• Denim colourway of the MOMENTUM 4 Wireless over-ear headphone
• Up to 60 hours battery life with Bluetooth and ANC active
• 42 mm dynamic driver with 6 Hz to 22 kHz frequency response
• Adaptive hybrid noise cancelling with Transparency Mode
• Bluetooth 5.2 with aptX Adaptive, aptX, AAC and SBC codecs
• Four beamforming microphones for clear calls

Sound and personalisation

The 42-millimetre dynamic transducer system delivers Sennheiser’s signature sound tuning, with a specified frequency response of 6 Hz to 22 kHz, sensitivity of 106 dB SPL at 1 kHz and total harmonic distortion below 0.3 percent at 100 dB and 1 kHz. Through the Sennheiser Smart Control app, listeners can adjust a built-in equaliser, use presets and apply Sound Personalization, which creates a profile based on individual listening preferences. Sound Zones and other app features allow settings to follow location. Codec support covers SBC and AAC for general devices and aptX and aptX Adaptive for compatible Android and other aptX sources, where aptX Adaptive adjusts bitrate and latency to conditions. Impedance is 470 ohms in active mode and 60 ohms in passive mode, the latter allowing wired listening to continue when the battery is empty.

Adaptive noise cancelling and transparency

The hybrid adaptive ANC system continuously adjusts noise reduction to the surroundings, reducing the low-frequency drone of aircraft, trains and air conditioning as well as everyday office and street noise. When awareness is needed, Transparency Mode lets external sound in without removing the headphones, with the level adjustable in the app. An adjustable anti-wind setting addresses wind noise in the noise-cancelling system outdoors. For listeners who move between focused work, commuting and walking outside in a single day, that ability to shift between isolation and awareness from the earcup or app is central to how the MOMENTUM 4 is used.

Battery, calls and controls

The built-in 700 mAh lithium-ion battery provides up to 60 hours of playback with Bluetooth and ANC on under Sennheiser’s stated test conditions. A full charge takes approximately 2 hours over USB-C, and a 5-minute quick charge provides approximately 4 hours of playback. Four digital beamforming MEMS microphones, two on each side, with automatic wind noise suppression handle voice pickup for calls, covering a microphone frequency response of 50 Hz to 10 kHz. Touch controls on the right earcup manage playback, volume, calls and ANC and transparency levels, while Smart Pause halts playback when the headphones are removed and auto on and off powers them according to use. Multipoint Bluetooth connection keeps two devices connected at once, such as a laptop for work and a phone for calls.

Design, wired options and accessories

At approximately 293 grams, with padded earcups that fold flat, the MOMENTUM 4 is designed for extended wear and for packing into its included carry case. Wired listening is supported in three ways: the supplied audio cable with 3.5 mm and 2.5 mm plugs for analogue sources, USB-C for digital audio and charging, and passive operation when the battery is depleted. Sennheiser includes the carry case, a USB-C charging cable, the audio cable and an airplane adapter in the box, covering in-flight entertainment systems as well as phones, laptops and portable players. Firmware updates are delivered through the Smart Control app.

In Denim, the MOMENTUM 4 Wireless combines the range’s longest battery life, adaptive noise cancelling and app-based personalisation in a colourway with a softer, less formal character than the standard finishes, making it the version for listeners who want the full MOMENTUM 4 specification with a distinct look.
