Superior Sound, Perfected for You

The TWM utilizes powerful Magneto-Static technology in a Hybrid Planar dual driver design for clear, detailed sound. A high-frequency Magneto-Static driver offers crisp, high-resolution sound even at low volumes, while the dynamic planar midrange/bass driver delivers deep bass and natural midrange. Custom hearing tests with Audiodo Personal Sound™ via the PSB Headphones App ensure precise sound balance, with Volume Dependent Compensation and four EQ presets for tailored listening experiences.

Signature RoomFeel™ Tuning

PSB's RoomFeel™ technology emulates the experience of listening to high-quality speakers in a well-designed room, creating a natural sound. This technology incorporates research on 'Room Gain,' which accounts for the warmth and energy that room boundaries add to a speaker's response curve. RoomFeel minimizes the 'in your head' sensation, offering an open, in-room listening experience with the M4U TWM, ensuring a non-fatiguing and natural sound whether you're on the go or at the gym.

Whether you're at home or on a call outdoors, cVc™ (clear voice capture) technology minimizes background noise, ensuring clear voice quality in any environment.
