Enjoy premium quality sound with advanced noise cancelling.

The M4U 2 Active Noise Cancelling headphones are at the pinnacle of PSB headphone performance, providing crisp and powerful sound that lets you hear the details of recordings in the noisiest environments. Using decades of acoustic expertise in developing award-winning audiophile speakers for home listening, and leveraging new scientifically-tested proprietary technologies, the M4U 2 headphones use RoomFeel™ technology to create a more spacious and natural sound while its highly-sensitive mics monitor the noise around you and cancel it out. They’re also comfortable, durable and easy to store, with a foldable design that fits into a small protective carrying case.


Built like the best PSB speakers
M4U 2 headphones are built to sound like the PSB speakers you love at home, deliver all-day comfort and easy to commute and travel with. Your favourite recordings are deeper, more powerful with a balanced sound signature that places instruments and vocals all around you. Engineered with RoomFeel™ led by legendary designer Paul Barton and his PSB acoustic team, the M4U 2 headphones have been scientifically-designed to make music so compelling that you’ll think it’s made for you.

Lose yourself in the details of your music.
PSB M4U 2 headphones allow you to escape the noise on flights, in busy working environments and on crowded city streets and let you focus on the sounds that matter. With advanced noise cancelling technology that utilizes highly sensitive external microphones to reduce the unwanted sounds, you can enjoy every subtle detail of your music, movies and videos without any compromise. The super soft ear pads are also designed for a complete over-the-ear seal to give you a quiet experience in any of three listening modes.

Designed for comfortable all-day listening
Working in close collaboration with one of New York’s most renowned industrial designers, David Farrage, PSB designed their class-leading noise-cancelling headphones with premium high-quality materials that set them apart. Lightweight with super soft two-way adjustable ear pads and an expandable headband, the M4U 2 is the perfect everyday headphone, providing you with a custom fit that lets you listen in style and comfort for close to 55 hours. You can also go battery-free and enjoy unlimited listening thanks to its passive listening mode.
