Description

M4U 9 – Premium Wireless ANC Headphones

The M4U 9 Premium Wireless Active Noise Cancelling Headphones redefine the expectations of PSB’s “True to Nature” sonic performance with all-new graphene-infused drivers and improved ergonomic comfort. Pair to your device, play music and make voice calls noise-free thanks to aptX™ Adaptive Bluetooth and cVc™ (clear voice capture) built-in. Powerful technologies like Personal Sound by Audiodo™ allow you to calibrate your left and right headphones separately so the music sounds just right, while PSB’s proprietary RoomFeel™ tuning and active noise cancelling leaves you with nothing but natural and open sound.

  • Premium Wireless Active Noise Cancelling Over-ear Headphones
  • Bluetooth HD wireless connection with Qualcomm® aptX™ Adaptive and cVc™ technology
  • Custom sound calibration with Audiodo™
  • Natural and open RoomFeel™ tuning
  • Graphene-infused drivers

Built for Premium Listening
Utilizing a new graphene-infused driver, the M4U 9 delivers improved damping, stiffness and efficiency for a truly immersive hi-fi audio experience. The M4U 9 Wireless Active Noise Cancelling headphones are at the pinnacle of PSB headphone performance, bringing PSB’s award-winning “True-to-Nature” sound signature to new sonic heights and providing crisp and powerful sound that lets you hear every detail of your favourite music and movies, even in the noisiest environments.

In Tune with You
Since each of us hear differently, there is no catch-all headphone setting that works for everyone’s unique hearing needs. Utilizing advanced algorithms, Audiodo Personal Sound™ checks your right and left ears separately through a series of audio tests and questions, correcting any hearing anomalies. It then quickly creates a personal hearing profile for you that compensates for anomalies in sound perception and hearing abilities, letting you fully hear PSB’s renowned “True-to-Nature” sound signature. The latest implementation of Audiodo includes a Volume Dependent Compensation feature so the M4U 9 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™.

The full featured PSB Headphones App turns your device into a remote control for your M4U 9’s, 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.

RoomFeel™ Realism
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 natural in-room listening experience through the M4U 9. Regardless of the environment you’re situated in, RoomFeel brings you the most natural, non-fatiguing listening experience even during long work days, journeys on transportation or binge watching sessions.

Active and Adaptive
Using adaptive technologies, the M4U 9 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. To block out the noise, the M4U 9’s all-digital active noise cancelling (ANC) capabilities utilize 4 digital MEM microphones to decrease audio conversion errors in audio processing for pure, focused listening, with two additional mics for cVc™ (clear voice capture) technology that delivers crystal clear voice quality for all your voice calls.

Luxe Mobile Listening
The epitome of comfortable listening is at your fingertips so you can listen longer and with noise-free focus throughout the entire day or night. Enjoy up to 25 hours of run time in Active Mode, or if you’re running low on battery, switch to two different modes of wired operation: 3.5mm wired connection, or via USB-C from the computer which recharges the batteries while you listen. Toggle between three different listening modes: ANC with RoomFeel, Active with RoomFeel or a Passive mode, using the physical switch on the headphones and mix in your surroundings by adjusting transparency levels through the PSB Headphones App Super soft earpads – fabric and leatherette – are included with the M4U 9, providing excellent seal so all that’s left is rich, detailed sound. The gyro-suspended earpads are tilted at 15 degrees for ideal ergonomic support, while the expandable headband features a fabric inner cover for optimal comfort.

Why Choose PSB

PSB Speakers is a Canadian loudspeaker manufacturer founded by legendary designer Paul Barton, whose work has long focused on combining scientific acoustic research with natural and highly approachable musical performance. Developed alongside extensive listening research conducted through Canada’s National Research Council, PSB products are engineered around the idea that loudspeakers should reproduce music with tonal accuracy, balance, and long-term listenability across real-world listening environments.

At HeyNow Hi-Fi, PSB occupies a particularly interesting space within the market because the range combines excellent engineering, practical usability, and strong value while remaining less commonly encountered than many mainstream loudspeaker brands. The result is a lineup that often surprises customers with just how refined, flexible, and musically satisfying the products are at their respective price points.

Signature Design and Sound

PSB products are known for their balanced and easy-to-live-with presentation. Rather than sounding exaggerated or overly analytical, the speakers tend to focus on tonal coherence, natural vocals, controlled bass performance, and broad compatibility across different amplifiers, rooms, and listening styles.

One of the standout areas within the range is the PSB Alpha iQ active streaming speaker system. Incorporating integrated amplification together with the excellent BluOS streaming platform, the Alpha iQ delivers a highly modern and remarkably complete Hi-Fi solution with minimal system complexity. For customers wanting genuine stereo performance without the need for multiple separate components, the Alpha iQ has become one of the most compelling compact streaming systems currently available.

PSB’s AM Series active speakers also offer a highly practical and musically engaging approach to modern desktop and compact Hi-Fi listening. Combining active amplification with strong tonal balance and excellent usability, they work beautifully within home offices, smaller rooms, and lifestyle-oriented listening spaces while still maintaining genuine stereo credibility.

The range also extends into architectural speakers, including in-wall and in-ceiling models designed for discreet distributed audio and home theatre integration, together with heritage-inspired passive speakers such as the Passif 50, which offers a modern interpretation of classic monitor-style loudspeaker design.

PSB Product Range

The PSB range available through HeyNow Hi-Fi includes active streaming loudspeakers, powered desktop speakers, passive loudspeakers, architectural audio solutions, and wireless headphone products designed for both home and travel use.

The Alpha iQ and AM Series in particular represent excellent opportunities for customers seeking high-quality sound with minimal complexity, while the Passif 50 appeals strongly to listeners who appreciate classic loudspeaker proportions and a more traditional stereo presentation.

PSB’s wireless noise-cancelling headphones also remain highly practical for travel, particularly due to their use of replaceable AA battery operation rather than fixed internal rechargeable batteries. For many travellers and long-term owners, this offers a level of convenience and longevity that is becoming increasingly rare within modern portable audio products.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide assistance with streaming integration, speaker matching, architectural audio planning, and complete system optimisation to ensure PSB products perform at their full potential within each customer’s listening environment.
