Highlights & Key Technologies

Experience Sennheiser's Signature Sound
Discover best-in-class sound with the audiophile-inspired acoustic system. Enjoy your favorite music like never before with the audiophile-inspired 42mm transducer system that delivers brilliant dynamics, clarity and musicality. Make the sound perfect for you using the built-in equalizer, presets, sound modes, and Sound Personalization feature, which tailors the audio to your individual hearing. The Sound Check function guides you step by step to create customized equalizer presets for optimal results.

Up to 60 Hours of Battery Life
Let nothing stand in the way of your listening pleasure. Keep on listening while you fly around the globe, with up to 60-hour battery life and fast charging capability that provides a further 6 hours listening in just 10 minutes. Smart Pause halts playback when the headphones are taken off and automatically resumes when they're back on your ears so you'll never miss a beat, while Auto On/Off rapidly powers up the headset when it's picked up and shuts down to save energy when not in use.

Adaptive Noise Cancellation and Transparency Mode
Go from total immersion to situational awareness with just a touch. The next generation Adaptive Hybrid ANC automatically adapts to ambient noise so you can stay immersed and hear every detail, even in noisy environments. Wind Noise Reduction can be set to Auto or Max mode to minimize disturbing wind or movement noise. Need to hear an announcement on the train or a question from your colleague? Just activate the versatile Transparency Mode at a touch to hear outside sounds without removing your headphones. You can adjust the intensity of both ANC and Transparency Mode using pinch and stretch gestures on the touch pad.

Premium Look and Feel
Enjoy exceptional comfort and streamlined style. The MOMENTUM 4's lightweight design features a padded headband and deep, yet soft, cushioned earpads to ensure exceptional and long-lasting wearing comfort. The low-friction hinge mechanism easily adjusts to give you a great fit without placing excess pressure on your head. The headphones are equipped with a sensor that automatically detects whether they are worn or taken off from your ears for the Smart Pause function.

Crystal-Clear Communication
Four digital beamforming microphones ensure high quality voice pick-up and automatic wind noise suppression for optimized calls and easier voice assistant access. The advanced microphone system uses two dual-microphone beamforming arrays (one on each side) to ensure you can be heard perfectly during calls even in noisy environments. The Sidetone function allows your own voice to be audible in the headphones during phone calls for more comfortable communication, with adjustable intensity.

Intuitive Touch Controls
The right ear cup features an intuitive touch pad that responds to tapping, horizontal swipes, vertical swipes, pinch gestures, and stretch gestures. Control music playback, adjust volume, manage phone calls, switch between ANC and Transparency Mode, and adjust their intensity all through simple gestures. The touch pad function can be deactivated to avoid unintentional entries when desired.

Versatile Connectivity
Connect via Bluetooth 5.2 with support for aptX Adaptive, AAC, and SBC codecs for high-resolution audio. USB-C connectivity allows direct audio streaming from Mac/PC/mobile devices, with the headphones serving as both audio output and input device. An analog audio cable with 3.5mm and 2.5mm jack plugs provides wired connectivity, and an in-flight adapter is included for aircraft entertainment systems. When the audio cable is connected, flight mode is automatically activated and Bluetooth is deactivated.

Smart Control App
The Sennheiser Smart Control app provides access to all functions and settings of the headphones. Customize sound using the built-in equalizer with predefined presets, sound modes (such as bass boost), or create your own settings. The Sound Personalization feature assesses your listening preferences and adjusts the listening experience according to your taste. Adjust ANC settings including Adaptive mode and Wind Noise Reduction, configure Transparency Mode behavior, manage Bluetooth connections, customize the headphones' device name, adjust Sidetone intensity, configure Smart Pause sensitivity, and install firmware updates. Voice prompts and sound signals can be activated or deactivated completely through app settings.
