Wireless Headphone with Adaptive Audio Technologies and Intelligent Features
Improving on three generations of award-winning headphone design, the M4U 9 is crafted with premium materials, adaptive audio technologies and intelligent features, bringing the ultimate in mobile listening.
The wireless active noise cancelling over-ear headphones implement new graphene-infused drivers which improve on damping, stiffness and efficiency to reveal PSB’s “true-to-nature” sonic signature, more crisp and powerful than ever before. aptX™ Adaptive Bluetooth technology enables fast and easy pairing with any device, with support for up to 24-bit high-definition audio.
The M4U 9 features all-digital active noise cancelling (ANC) capabilities utilizing 4 digital MEMS microphones to decrease audio conversion errors in audio processing for pure noise-free listening, while two additional mics for cVc™ (clear voice capture) technology deliver crystal clear call quality.
A three-position mode switch on the M4U 9 allows you to choose between ANC with RoomFeel, Active with RoomFeel or a Passive mode. Gyro-suspended, fabric and leatherette earpads tilted at 15 degrees provide excellent seal and ergonomic comfort for an extended listening time of up to 25 hours in Active Mode.
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.
