Created to deliver the clear, natural sound of a live performance, PSB’s exclusive RoomFeel technology adds layers of lush realism to all your favorite recordings. Carefully developed to produce ‘Room Gain’ – the energy and clarity that a room adds when listening to high-quality loudspeakers. RoomFeel places the music seemingly around the listener, resulting in a truly stunning musical experience. Designed to go wherever you and your music go, RoomFeel brings the most accurate sound directly to your headphones.

The M4U 8 model allows you to listen to music wirelessly with Bluetooth aptX HD – the latest 24-bit high definition version of the most universal wireless technology – the high fidelity version of Bluetooth. There are also two different wired modes of operation; 3.5mm wired connection, or via USB from the computer, which recharges the batteries for wireless operation. Active Noise Cancellation (ANC) is remarkably sophisticated and effective, utilizing 4 microphones (others use only 2) which offer a ‘listen through mode’ allowing you to momentarily listen to the outside world as well as the ability to answer your connected phone. There is also an Active Mode, and Passive Mode (without batteries). Listen all day and all night with up to 15 hours of run time in Bluetooth or Active modes. When you’re out of batteries, switch to Passive Mode without missing a beat.

Listen longer in extra comfort. Our unique two-way adjustable ear pads are gyro-suspended for optimal ergonomics and supreme comfort. Super soft ear pads and light weight make the headphones “disappear”, leaving only rich, detailed sound. The expandable headband also easily adjusts for a more customized fit. Don’t let anything come between you and your music.
