Whether you're a music enthusiast or a frequent traveller, the M4U 9 offers a perfect blend of cutting-edge technology and comfort.

Built for premium listening

The M4U 9 redefines premium listening with graphene-infused drivers, enhancing damping, stiffness, and efficiency for an unparalleled audio experience. These headphones continue PSB's industry-leading sound signature, delivering crystal-clear audio even in noisy environments. Its adaptive technologies mean you can rely on high-quality audio wherever you are with aptX™ Adaptive Bluetooth for low-latency audio and all-digital active noise cancellation. Experience premium audio anywhere life takes you.

Tuned just for you

Recognizing that everyone's hearing is unique, the M4U 9 employs Audiodo Personal Sound™. Each ear is assessed using precise audio tests and questions, and a personalized hearing profile is generated. Plus, four EQ presets, including RoomFeel™ , allow you to fine-tune your audio experience. Use the intuitive PSB Headphones App to control your settings, such as noise transparency and EQ presets.

Get out of your head

Discover an unparalleled listening experience with PSB's innovative RoomFeel technology. This advanced feature recreates the feeling of listening to high-quality powered speakers  in an acoustically optimized room. By mimicking the natural sound dispersion of speakers, RoomFeel takes the sound out of your head, providing a spacious and lifelike soundstage. Whether at home, on a journey, or immersed in entertainment, RoomFeel ensures that every note and detail is rich, natural, and open.

Listen longer in comfort

Crafted with comfort in mind, M4U 9 features gyro-suspended earpads, thoughtfully tilted at 15 degrees to provide ergonomic support. Meanwhile, its expandable headband, complete with a fabric inner cover, enhances overall comfort. Available in both fabric and leatherette, the soft earpads create an exceptional seal, preserving your sound quality. Enjoy 25 hours of runtime, or switch to wired operation through the 3.5mm or USB-C connections for uninterrupted listening.

Perfect for Active Kids
Size: 4 Big Kid, Color: Black, Size: 4 Big Kid, Color: Black
My son loves these shoes. He says they’re really comfortable and lightweight, and he can run and play in them easily. So far they’ve held up well. He can fit them. Non Velcro and slip resistant.

Good, but not great! Insert kept falling out.
Size: 3 Big Kid, Color: Black
I bought these for my 8 year old and the insert was loose and had to be played with multiple times before I could get it to stay in place. I eventually had to place a double sided sticky pad to get the insert to stay.
