PSB M4U 8 MKII Headphones

Audiodo Personal Sound™ is a calibration technology that maps your unique hearing profile to correct for individual sensitivities. By taking a quick test via the companion app, the headphones adjust the audio output to ensure you hear every detail exactly as it was intended for your ears.

Yes, the M4U 8 MKII supports a passive mode. You can continue listening using the included 3.5mm cable even when the battery is completely depleted, though active features like noise cancellation and RoomFeel will not be available.

RoomFeel is designed to mimic the natural, open sound of high-end loudspeakers in a treated room. It adds a sense of space and warmth to the audio, preventing the 'in-your-head' feeling common with many closed-back headphones.

They are designed for comfort with circumaural, synthetic leather earpads and a spring steel headband. The 15-degree angled earcups are specifically engineered to follow the natural contour of your ears, reducing pressure during long listening sessions.

You can expect up to 25 hours of battery life when using the headphones in standard wireless active mode. If you enable Active Noise Cancellation, the battery life is approximately 18 hours.

Yes, they feature aptX HD Bluetooth, which allows for high-resolution, near-lossless wireless audio streaming from compatible devices. For the highest possible fidelity, you can also use a wired connection via the USB-C or 3.5mm input.
