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.

Active and Adaptive

The M4U TWM headphones adapt to your surroundings as you go about your activities. These headphones offer seamless pairing with aptX™ Adaptive Bluetooth, ensuring high-quality sound with low latency for gaming and movie watching. 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.

Portable and easy extended listening

These earbuds feature convenient click buttons for volume control, track skipping, and calls. The smart charging case offers wired USB-C and wireless charging options, providing 8 hours of playback and 24 hours of backup power. Included are three sizes of silicon tips for noise isolation and secure fit. With an IP65 rating, they are sweatproof, water-resistant, and dustproof, perfect for active lifestyles. The PSB Headphones App enhances control with sound settings, Audiodo profiles, noise transparency levels, EQ presets, and battery monitoring.
