High-performance wireless noise cancelling headphones PSB’s award-winning “true-to-nature” sound signature All-digital adaptive noise cancelling (ANC) for pure noise-free listening Custom audio calibration with Personal Sound by Audiodo™ Sound tailored to youNo two people hear the same — hearing will even differ between the left ear and the right ear in the same person. Many factors affect hearing, including the shape and size of ears and ear canals, as well as damage to cilia from loud noises or infection. These combined with personal preferences and everyone’s unique neurological patterns means that the sophistication of human hearing as a sense is often taken for granted. Through a series of audio tests and questions, Audiodo’s Personal Sound technology quickly creates a personal hearing profile for you that compensates for anomalies in sound perception and hearing abilities, allowing you to fully reveal the True-to-Nature sound signature PSB Speakers is known for. A full-featured app allows you to personalize your listening experience and keep your headphones updated with the latest firmware updates and codecs. Adjust the sound of your headphones to fit your personal hearing profile using Audiodo’s breakthrough Personal Sound technology and customize the sound settings to your preferences and environment. Track your battery status, access user manuals, and control the devices your headphones are connected to. Behind RoomFeel technologyDesigning headphones and designing speakers are different disciplines, and while many companies use similar criteria for speakers meant for in-room listening as for the speakers clamped onto the sides of your head, PSB takes a different approach. With the latest generation of its groundbreaking RoomFeel technology, PSB uses precisely designed target curves to recreate the experience of in-room hi-fi listening in headphones. Based on seminal research in the field of psychoacoustics, while also designing around the listening fatigue that is often associated with active noise cancellation technologies, the M4U 8 MKII offers a natural listening experience even during long journeys, binge-watching sessions, or marathon work days. Block out the noiseThe PSB M4U 8 MKII Headphone features an all-new, all-digital signal path design that ensures state-of-the-art active noise cancelling capabilities, cutting down the number of conversion steps required in the audio chain to keep it clean and noise-free. External sounds are detected, analyzed, and cancelled out in nanoseconds across the widest possible frequency and decibel ranges. Highly sensitive Knowles MEMS microphones cut down on system noise to deliver crystal clear call quality, while aptX HD Bluetooth makes your music sound like it is being piped straight from the studio. True comfort, portability and functionality.Toggle easily between passive active, and active noise cancelling modes to suit your environment using the physical switch on the headphones, and fine tune the settings with the intuitive PSB Headphones Control app. Ergonomically designed, soft-foam earcups and top-quality materials in the headband allow for full comfort listening, even during marathon calls or travels. Extended battery life — trackable using the PSB Headphones app — delivers up to 50% more listening time over the previous generation M4U 8.
