PSB M4U TWM Wireless Earbud Headphone - Black

Hybrid Planar Earbuds with Advanced PSB Technologies

If you thought that getting earbuds as opposed to full-size headphones meant settling for a sonic compromise, wait until you hear the M4U TWM from PSB. These are far from your typical earbuds. These boast a planar design with advanced PSB technologies.

The M4U TWM earbuds leverage powerful Magneto-Static technology in a Hybrid Planar dual driver design, utilizing the same technology found in high-end magneto loudspeakers and fitting them into remarkably compact earbuds. Dedicated transducers, one for high frequencies and one for low frequencies, work together to make the in-ear listening experience truly pristine, reproducing sound with crisp highs, natural midrange and deep lush bass.

Enhanced aptX™ Adaptive Bluetooth technology keeps everything in sync from movies to games with dynamic low latency and an adaptive bit rate. Convenient features like hard click buttons on both earphones make music control and voice calls hands-free and intuitive, while a smart USB-C charging case delivers a maximum of 32 hours of extended play time (8 hours out of the case and 3 additional charge cycles in the case).

Perfect for Your Active Lifestyle

Wear them without worry. The M4U TWM earbuds have earned the industry's IP65 rating for protection against sweat, dust, and weather. That means in addition to enjoying them in the home and office, they're great for travel, commuting, and exercise, too. Lightweight and secure, they will fit your active lifestyle.

Sound Optimization with Audiodo Personal Sound™

An integration with Audiodo Personal Sound™ technology is one of the most unique features. The breakthrough technology uses a non-replicable set of algorithms which allows you to calibrate your headphones in a way that accommodates for the listening qualities of your left and right ears independently.

After completing a quick and easy hearing assessment accessed through the PSB Headphones app, Audiodo Personal Sound™ maps out a precise and thorough understanding of your hearing, calculates what changes need to be made based on personal sound perception, and formulates a compensation curve that can be applied to the overall headphone sound.

Natural 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 the head’ by recreating an open and natural in-room listening experience through the M4U headphones.

PSB Headphones App

All headphone settings, including Audiodo Personal Sound™ tests and Transparency modes, are accessed centrally through the PSB Headphones app, a full-featured app that allows users to adjust settings, check battery levels and regularly keep the headphones up-to-date with the latest firmware updates and codes.
