The headphones implement sound personalization options through a partnership with Audiodo Personal Sound™ along with PSB’s proprietary RoomFeel™ technology. The next-generation M4U 9 and M4U TWM designs feature improved engineering, better componentry and overall stunning presentation of musical detail.

M4U 9 – Premium Wireless ANC Headphones
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 luxe 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 users to choose between ANC with RoomFeel, Active with RoomFeel or a Passive mode. Gyro-suspended, fabric and leatherette ear pads tilted at 15 degrees provide excellent seal and ergonomic comfort for an extended listening time of up to 25 hours in Active Mode.
