Superior Sound, Perfected for You

The TWM leverages powerful Magneto-Static technology in a Hybrid Planar dual driver design which reproduces sound with minimal distortion, crisp highs, natural midrange and deep, lush bass. Dedicated transducers, one for high frequencies and one for low frequencies work together to make the whole mix sound truly pristine. The high frequency Magneto-Static driver utilizes a thin, low mass diaphragm driven in a static magnetic field to move the diaphragm at ultra-high speeds with minimal distortion for crisp, clear, ultra-high resolution sound reproduction, even at low volume levels. The dynamic planar midrange/bass driver combines deep, fast bass and rich, natural midrange with a wide soundstage. The result of this Hybrid Planar design is destined to be pure music to your ears.

While most earbuds assume that your hearing is consistent on both ears, the reality is the opposite - no two ears hear in the same way. Accessed through the PSB Headphones App, a custom hearing test by Personal Sound by Audiodo analyzes your left and right ear separately and maps out a precise understanding of your unique hearing. The latest implementation of Audiodo includes a Volume Dependent Compensation feature so the TWM can accurately match the timbral balance of the music at any volume level you choose. In addition, there are four EQ presets you can engage for specific music or movies - tighter bass, more detail, better dialogue and the default preset - RoomFeel.

Signature Roomfeel Tuning

Created to deliver rich and natural sound through headphones, the next generation of PSB's proprietary RoomFeel technology mimics the experience of listening to a pair of high-quality, full-range speakers properly set up in a good room. Carefully developed, using research and expertise around 'Room Gain' - the energy and warmth that room boundaries add to the response curve of a flat-measuring loudspeaker, RoomFeel makes the music feel less 'in your head' by recreating an open and in-room listening experience through the M4U TWM. Whether you're moving through a busy street, catching transportation or at the gym, RoomFeel brings you the most non-fatiguing and natural sound possible.

Active and Adaptive

Using adaptive technologies, the M4U TWM headphones adjust to your environment while you move, work and play. Pair the headphones to your device seamlessly with aptX Adaptive Bluetooth, a 24-bit, HD universal Bluetooth technology that uses a variable bitrate to enable low-latency audio reproduction for playing games or watching movies while still offering the best possible sound quality. Whether you're at home or outside while taking a voice call, cVc (clear voice capture) technology suppresses any background or ambient noise around you, so you still transmit crystal-clear voice quality no matter what environment you're in.

Easy, Extended Listening

Hard click buttons on both earphones make volume control, skipping tracks, and voice calls easy and intuitive. The smart charging case with auto-pairing offers both wired USB-C and wireless charging options. Enjoy 8 hours of playback time and an additional 24 hours of charge stored in its accompanying case.

Included with the earphones are 3 sizes of comfortable silicon tips to provide excellent noise isolation and an in-ear fit that stays put, even if you're moving. The earbuds are IP65 rated, making them sweatproof, water resistant, dustproof and well-suited for any active endeavor be it the gym, cycling, running or a long commute.

The full featured PSB Headphones App turns your device into a remote control for your M4U TWMs, giving you access to specific sound settings and features that you can adjust for a richer listening experience. With the tap of a few buttons you can create a sound profile using Audiodo, control noise transparency levels, choose from preset EQ settings, check battery level and more.
