PSB M4U 2
Noise-canceling headphones with in-line microphone and remote (Black)
Our take on the PSB M4U 2 by Crutchfield's Dave Bar
Precise, detailed PSB sound in a portable design
Long revered for their musical honesty and superior value, PSB speakers have been a favorite of audiophiles and industry insiders for over 40 years. Now PSB has created headphones that pack the same sonic realism and precision as their speakers into a portable package you can take with you anywhere. The PSB M4U 2 with active noise-canceling technology reproduces your music with exquisite detail and clarity, while isolating you from noisy environments. You can enjoy your own private concert in peace, without distractions from the outside world.
"It's hard to describe the M4U 2's sound because it's so close to flawless and so free of an identifiable character. The bass sounds extremely smooth and tight, the mids are exceptionally clear, and the highs are rich and detailed. Not only does the M4U 2 sound like a really great speaker, it sounds like a great speaker in a great listening room."
— From Brent Butterworth's review in Sound+Vision Magazine, June, 2012

Switch between your calls and music with ease
The M4U 2's in-line remote and microphone make it easy to answer and end calls, and pause, play, or skip through the songs on your iPod®, iPhone®, or iPad®. PSB includes two detachable headphone cords that feature a handy push-to-hear control that lets you mute the audio and amplify outside sounds to carry on a conversation with those around you without removing your headphones. For travel, the supplied airline adapter lets you easily plug into the in-flight entertainment.
Power and comfort
You can select from three different operating modes to fit different listening situations. Passive mode allows you to enjoy your tunes without battery power — ideal for those times when you're playing music through high-quality home audio gear or a headphone amp. Switch to active mode, and the headphone's built-in amplifier kicks in to provide an added boost that turbocharges the sound coming from your portable player. Or, engage the active noise cancellation circuitry when you just want to tune out the world and relax to your music uninterrupted.
Along with delivering fantastic sound, a truly great headphone has to be comfortable. The M4U 2's soft padded earcups feature a two-way adjustable pivoting design for a secure, custom fit and hours of listening enjoyment. Dual input connections let you conveniently plug the cable in on either the left or right earcup. The folding design and included storage case make them easy to take along.
From our review of the PSB M4U 2 noise canceling headphones
"These are my favorite noise-canceling headphones I've experienced to date. They're open, bass-forward without being unfocused or obnoxious, well-extended and overall, extremely pleasant to listen to. Plus, they are comfortable, mobile phone friendly and easy to manage while sitting in a coach seat."
— Woody, Crutchfield Home A/V writer
I got these based on the price cut from 400 to 300. Thinking they must be worth it. Sound quality is good and built quality feels nice and tight.

Overview: The PSB M4U 2 headphones are part of the Music for You (M4U) series of high performance headphones. The M4U 2 has Active Noise Cancellation, powered by two "AAA" batteries (supplied), which eliminates external noise. The headphones come with two 5' cables (one with an in-line remote/microphone and one without), airline and 1/4" adapters, an extra set of earpads, and a semi-hard zippered storage case.
Operation Modes: The M4U 2 headphones feature three modes of operation, controlled by a 3-way switch on the right earcup: Active Noise Cancellation (ANC), Active Mode, and Passive Mode. When ANC is activated, external noise is picked up by the built-in microphones and canceled by introducing an inverted (out-of-phase) signal. At the same time, the incoming audio signal is amplified by the built-in amplifier. In Active Mode, the audio signal is amplified, but there is no Active Noise Cancellation. In Passive Mode, both active circuits (ANC and amplifier) are shut off, and the music is driven by the connected device. You can listen in Passive Mode when your batteries are exhausted.
Room Feel: The M4U 2 has Room Feel technology, which gives the headphones the same true-to-nature sound as a pair of PSB's in-room loudspeakers.
Ear Pads: The soft earpads are designed for comfort and fit. The ergonomic ear pads are gyro-suspended and self-adjusting to give you a precise fit. The M4U 2 comes with a spare pair of earpads.
Cables: The M4U 2 includes two 5' tangle-free cables, which can plug into either side. Both cables have an in-line Monitor button (see Monitor Function below). One cable is designed for use with your smartphone, and includes an in-line remote and microphone. The remote lets you answer and hang up your call, and play/pause, skip forward, and skip backward. The controls are compatible with iPhone and Blackberry. The other cable has no in-line remote/mic. A dual-input airline adapter and 1/4" stereo adapter are included.
Note: The cables must be plugged in with the straight end in the headphones and the right-angled end in the playback device.
Monitor Function: Both included cables have an in-line Monitor button. When pressed and held, the current audio track is attenuated by 30dB, and the surrounding sounds will be amplified through the headphones. The Monitor Function only works when the headphones are in Active Noise Cancellation (ANC) mode.
Batteries: The M4U 2 noise-canceling headphones are powered by two "AAA" batteries (supplied), which are inserted into the left earcup. Battery life is approximately 55 hours on average when using Active Noise Cancellation. You can use rechargeable batteries if desired, however, battery life will be shorter.

Product reviews from the Crutchfield Labs
by Woody Sherman
We all know PSB makes great speakers. Just how good, exactly, are their headphones, then? Read on: looks like someone's impressed.
Why did you buy this?
Product Comparisons, specifications, value, reviews. [ Wood Feb 12, 2017 ]
Had a pair of Bose crap out on an 18 hour flight. Crutchfield was able to deliver with overnight shipping on memorial day weekend so I could have music and sound on my return flights home. Oh and PSB sound is second to none. The noise cancelling isn't as great as the Bose but the sound improvement is off the charts! [ Jason Jul 14, 2016 ]
Really good quality. [ AdamR May 25, 2016 ]
Listen to your adviser. [ Philip Apr 06, 2016 ]
I had bought these same headphones about two years ago, but unfortunately they were stolen. I have difficulty hearing, especially dialogue when watching DVDs and movies. These headphones were the best I could hope for, allowing me once again to enjoy music, plays and movies. The sound is natural and realistic, music beautifully detailed, with no harshness or distortion regardless of volume. [ ARLINE Mar 24, 2016 ]
great reputation, great sound. I had two pairs of the bose quiet comforts and these sound MUCH better as well as are made better. [ THOMAS A Jan 11, 2016 ]
Well-known brand with good reputation for quality. [ PATRICK Dec 20, 2015 ]
compare before you buy , this one had more options [ Victor Jan 19, 2017 ]
Style, reviews, PSB speaker reputation. [ Nicholas Dec 22, 2015 ]
3 questions already asked
Great question! I think you might have to contact PSB directly. I'm also thinking of replacing my microphone cable. I think my microphone cable went bad because I was getting loud popping & screeching noises. I switched to the cable w/o a microphone & haven't had the same problems. But, I think PSB would have to send me a replacement (not Crutchfield). [ Jeffrey Aug 11, 2016 ]
Obvious question, but did you try PSB? [ Roy Aug 10, 2016 ]
I have used my PSB M4U 2 on my iPad and on my Kindle Fire. I have facetime and skyped and it works great. [ JOHN Dec 11, 2014 ]
Works with iPhone. Not sure about Android. [ CHARLES E Dec 11, 2014 ]
I don't know about i devices, but I can confirm it works with both the android moto x and LG/Google nexus 4 [ ERIC Dec 10, 2014 ]
Hey Sam, I have these now, use them on my ipad all the time, but I can't tell you if they work on a iphone, I don't have one. They are great by the way, would recommend them, especially if you travel by air. Good luck. Phil [ PHILIP Dec 10, 2014 ]
I have used it on my iPhone 5S and iPhone 6 and it works. [ FAISAL R Dec 10, 2014 ]
Yes, I have used this device at times when talking on my iphone and the microphone was fine. [ JULIE Dec 10, 2014 ]
4 answers The active noise canceling function and amplifier isn't working. I've put in two sets of new batteries and made sure they were inserted properly, but nothing seems to work. I went back to the quick start guide and found you had to press and hold the "m" button, but that didn't do anything. The headphones are incredible even on passive mode, but could you give some suggestions on what to do? [ John Jan 04, 2014 ]
Hi John, It sounds like you have tried everything that I thought of as well. Do you know if the headphones are still under warranty? [ BRETT Jan 06, 2014 ]
John, I own these PSB headphones as well and fortunately for me, I have had no problems like this at all. I do agree they are terrific sounding headphones and in my opinion are even better in active mode. The noise cancelling mode works well (though probably slightly less well than the Bose equivalent) but the sound quality more than make up for that. However, that being said, it simply sounds to me like this pair is defective in some way. The only other answer is that all the batteries just happened to be dead. You should probably send them back and ask for a new pair. Once you get them working I'm sure you will be quite happy with them. Andy [ ANDREW Jan 06, 2014 ]
I've had mine for about a year. I would send them back, sounds like their problem. But rest sured once fixed they are GREAT! And we'll worth the effort. Phil [ PHILIP Jan 05, 2014 ]
