Tuned to your hearing

Use the intuitive PSB Headphones App to manage settings such as noise permeability and EQ presets.

Listen outside your head

Experience an unparalleled listening experience with PSB's innovative RoomFeel technology. This advanced feature mimics the feeling of listening to high-quality speakers in an acoustically optimized room. By mimicking the natural soundstage of speakers, RoomFeel takes the sound out of your head and creates a spatial and lifelike soundstage. Whether you're at home, on the road or completely immersed in entertainment, RoomFeel ensures that every note and detail sounds rich, natural and open.
