Superior Sound

Enjoy your favorite music like never before with our audiophile-inspired 42mm transducer system that delivers brilliant dynamics, clarity and musicality.

Your way

Make the sound perfect for you using the built-in EQ, presets, sound modes, and Sound Personalization feature, which tailors the audio to your individual hearing.

New Adaptive Noise Cancellation and Transparency Mode

Go from total immersion to situational awareness with just a touch.

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 look & feel

Enjoy exceptional comfort and streamlined style.

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

Meanwhile, the low-friction hinge mechanism easily adjusts to give you a great fit without placing excess pressure on your head.

Smart & easy

Let nothing stand in the way of your listening pleasure.

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.
