Pros: Excellent frequency response, very balanced sound. Excellent, punchy bass, energetic mids/treble. Great imaging, timbre & soundstage for closed cans.

Cons: Slightly heavy. Comfortable for up to 2-3 hours.

I needed a closed pair of headphones to use during late-night listening sessions, when my wife and daughter are asleep, and where my (VERY) open-backed Grado PS500's leaked too much sound. The Grado's are amazing, and had they made a closed headphone, they could simply sign me up. So I began a journey to find the ideal audiophile closed headphone, which would also isolate noise effectively in a passive way, and ideally be portable. I tried the Beyerdynamic DT1350, great treble, punchy bass, and good mids. It just wasn't as "FUN" as I was looking for. Additionally, it got uncomfortable being supra-aural on sitting on the ear. I also tried the VModa M100, as I had read it was more accurate than their previous offerings. Ok, it is incredibly built, military grade even. But it was just still too colored for me, adding bass in places that didn't need it, and overpowering the mids. The treble was fairly good, but a little rolled off at the limits. Next I tried the Sennheiser Amperior. This is a good headphone, and many will like it. I thought the highs were a bit zazzy and hot, especially with "S" and "T" sounds. Of course, the source was critical, and the better the quality of the file, the better the output. I just couldn't put my finger on why I didn't want to keep them, but the clamping force was the deciding factor. Throughout this search of trial and error, I came across several glowing reviews for the PSB M4U 2's, which featured active noise cancelling. I had never been a huge fan of the way added electronics altered the sound quality and transparency of these types of headphones, but many respected audio publications said they were different. Then I read that PSB had recently released a new model without the active noise cancelling. It was difficult to find a review for this pair specifically, but I decided to pull the trigger. WOW. This is the first headphone that Paul Barton of PSB has introduced, and they knocked it out of the park. These are really phenomenal sounding headphones.

Treble: These have as close to a perfect, extended treble for their price that I could possibly imagine. They have excellent resolution and detail, easily keeping up with phones 2-3x their price. They have an extremely balanced top-end that has sparkle, energy and impact, rendering all range of instruments, both electric and strings/percussion with lifelike precision. They never fatigue me and have little to no sibilants. Being a drummer, the realistic snap of snares is a special treat.

Mids: Fantastic, slightly forward, with just the right amount of presence and weight to immerse you in the music. Great with both male and female vocals, and well rounded with all genres, from Rock to Hip-Hop, EDM to Classical. Truly, it is hard to find faults with the frequency range and presentation that Paul Barton and team engineered into these beauties.

Bass: Awesome. Awesome. Awesome. Punchy, able to achieve sub-bass, and so accurate and fast. They do their best to add nothing to the original intended sound, but they can really slam when the song calls for it. I've played them pretty darn loud with my Nuforce Icon HDP, and I cannot get them to break-up.

I'm just in awe that these are only $299. Audiophile steal. Period. Please don't feel trepidation to make the purchase due to the low amount of positive reviews online. Folks who have heard the M4U 1 and the M4U2, and compared them back to back, have preferred the transparency and naturalness of the M4U1. You're not getting less headphone if you don't care about the active noise cancelling. They myriad of reviews are correct. Buy these, you won't be disappointed.

Happy Listening!


Very interesting. I'm conditioned to Grado SR125i's and looking for something closed-backed for the office. I love mids and hate sibilance. If it comes down to ordering headphones with no test drive I may go for these.
Nice review, where did you pick them up for $242.00? still tossing up between these or the beyerdynamic T 70p i really like them but as you mentioned there not comfortable for extremely long periods so haven't decided yet.
Great review and I completely agree. Even though I prefer the coloration of the M-100, the PSBs are excellent. I am also looking forward to their upcoming release from sister company NAD which is also designed by Paul Barton.
Hey Random Guy! I actually picked up Used-Like New on Amazon through one of their vendors. Still had same warranty and return policy so I took a chance. They arrived clearly never have been used. Score! I haven't heard the T70P, but from everything I read, they are the weak link in the Beyer lineup. Maybe too lean for fun stuff. These PSB's are accurate, but still have PRaT. I say try em and return if you really don't care for them. I think the low price is throwing most audiophiles off. Hope that helps!
Can you comment on comfort wearing them with glasses? If you don't usually then maybe while wearing sunglasses?
Probably too late to help Commando^^, but to get this info out there: I am right now wearing PSB M4U 1s with glasses, and it's one of the most comfortable headphones with glasses I've tried. Ot comes with two sets of ear pads, and I'm wearing the second smaller pair, which for me work wonders for the comfort and the sound.
