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.

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.

Must for subwoofers. True 2mm spec. High quality.
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.

Good stuff !
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it.
