Sennheiser Momentum 4 Wireless Headphones

Full immersion – Our next generation Adaptive Noise Cancellation automatically adapts to ambient noise so you can stay immersed and hear every detail, even in noisy environments.

Situational awareness – 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.

Premium comfort – The M4’s lightweight design features a padded headband and deep, yet soft, cushioned earpads to ensure exceptional and long-lasting wearing comfort.

Perfect fit – The low friction hinge mechanism easily adjusts to give you a great fit without placing excess pressure on your head.

Up to 60-hour battery life – 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.

Never miss a beat – 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.

Smart Control App – For a truly tailored experience, download the Sennheiser Smart Control app, that makes it easy to customize the sound using the Built-in EQ, sound modes and the new Sound Personalization feature. This assesses your listening preferences and adjusts the listening experience according to your taste.
