I personally use it with a portable amp, which boosts its performance significantly. **Q: Is there leather used?** A: Leather cannot be used in headphone pads because leather does not breathe. Your ears would be sweating non-stop if you use leather. I do not know of any headphone manufacturer that uses leather pads. **Q: Is there any headband cushion pad replacement? Mine starts to crack** A: as far as i know they don't offer replacement anything, extremely poor customer support from this company, will never buy their products again. **Q: Did they ever fix the poor build quality on these? years ago I returned 2 pairs , the plastic cracked on the headband from simply just wearing them** A: If you want to keep them and dont mind doing a little leg work, someone was nice enough to actually post a 3D printable file for the part: https://www.thingiverse.com/thing:2196782 I price out having a shop do it and it came out to less then $30. I have actually tried out probably 10 other head phones from different companies some costing 2-3 times as much and cant find another pair I like. The only ones that came close was the NAD but that probably because the were designed by the same engineers. Problem is they were not as comfortable. ## Customer Reviews ### ⭐⭐ 2.0 out of 5 stars Unimpressive sound, poor quality control *by B***D on Reviewed in the United States on June 16, 2013* I am really disappointed in these headphones. I had done a lot of research in my quest to find the best pair of cans around $300 and finally decided, after much rumination, on these PSB M4U's. I ended up returning them after two weeks when they started to fall apart. I do think these are good sounding headphones but in my personal opinion, my Yamaha RH5MA and ATH M50's both perform better, are more comfortable and have better build quality while being ¼ to ½ the cost. Although they arrive in gorgeous packaging, right out of the box I had a problem. First, the straight cable (without the iPhone controls) had no left channel. I tried them around, checked my other headphones and outputs to no avail, they sent me a bad cable. This is not a huge issue but it's really frustrating that it wasn't discovered during quality control. Then, as soon as I put the headphones on, one of the metal covers next to the headband fell off. There are two tiny, eyeglass sized screws that screw into plastic posts. The posts are really weak and the screws had broken the plastic threading. This is a design flaw that could have been very easily rectified with a snap latch or even glue. I thought it might be a fluke occurrence until the other metal cover fell off a few days later. I must admit that this lack of quality control definitely colored my opinion of the sound. The ear pads seemed very comfortable at first but I quickly grew tired of them pressing into my ears, I don't think my Yamaha RH5MA or ATH M-50's are the most comfortable cans in the world either but these were not better in my opinion. The sound is the most important feature to me and I was not impressed. I actually prefer my Yamaha RH5MA over these and I think the ATH M-50's are far superior. After about 40 hours of use, I didn't find the soundstage to be any better than the much less expensive others I have. Out of desperation, I ordered a pair of Beyerdynamic AMS-DT-990-Pro-250 ohm cans that I got on Amazon for $171.25 including Prime express shipping. What a difference! The DT-990 Pros have an awesome soundstage right out of the box without any burn-in, While they are not bass heavy, they have plenty of bass for me and the mids and highs are incredible for a pair of $171 cans. I am a wannabe audiophile, just starting to build my system over the past year so I have a long way to go but here is what I am using now:Iphone 4S and Lenovo E530 laptopFlac or Apple lossless files, no MP3's.Traveling, I use a Fiio E11 and I just bought a Fiio E17K to which I will be adding the E09K desktop amp. As far as a sample of music: While I like to claim to have an eclectic taste, it's really just sadly bizarre. For comparison purposes, I used all of the following music on each of my four headphones: Fleetwood Mac - Tusk, Metallica - Unforgiven, Barry White - You're the First, the Last, My Everything, The Who - Behind Blue Eyes, Eva Cassidy - Over The Rainbow, Megadeath - Symphony of Destruction, Bruce Hornsby - The Way It is, Santana - She's Not There and Europa, Leon Redbone - Come and Get Your Love, and, because I was in high school in the 70's and it was played as the last dance at every single school dance from sixth grade through my senior year of high school - Led Zepplin - Stairway To Heaven.The M4U's just didn't seem to have the clarity that I heard in the DT-990's or even the ATH M-50's, the bass was about the same and while the mids were more clearly defined than the Yamaha and Audio Technica, it didn't match the DT-990's which had zero burn-in.Also unimpressive was the "gyro" mounted ear cups. They were no better than the ATH M-50's, heavier and more compressive than the Yamaha RH-5 and nowhere close to the level of comfort of the DT-990's. Yes, the Dt-990's make one look like Lando Calrissian's sidekick, Lobot on Star Wars but they are soft, gentle on my skull and the adjustment stays put when I take them off and put them down.Pros: Less sound leakage than the others listed above, great sound if they were around $150 , lots of attachments, beautiful packaging and a nice semi-hard case plus extra ear pads.Cons: Sounded no better than the $50 Yamaha RH-5's, uncomfortable if you have a size 7 or larger head or delicate ears, unimpressive soundstage and mids plus highs could be a bit painful at volume (no worse than the cheaper cans).I was really excited about getting these phones, I had very high expectations, obviously much too high, and I assumed that the quality control would be excellent. These really do sound nice and the design is pretty cool but for $300, I believe that they are about twice as much as they are worth and do not hold a candle to the BeyerDynamic DT-990 Pro cans. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Paul Barton's Grand Slam Headphones *by B***I on Reviewed in the United States on May 5, 2013* Paul Barton hit this one out of the ballpark. I bought these cans solely on recommendations from reviewers I've come to trust, and the M4U 1s exceeded every parameter I judge essential in headphones: appearance, quality of construction, comfort, and most importantly, sound. Despite being a closed 'phone, the M4Us are spacious, highly detailed, and extremely well-balanced. I have found no musical genre lacking, although admittedly I have used only CDs as my sound source, and only through my home system. A Pioneer Elite CD player coupled with a Denon 2000 integrated amplifier also provided the sources for my Audio Technica M50s, AKG 240s, and Senn 600s--all good phones, but the M4Us are unquestionably the best phones I've ever owned. I've got close to 150 hours of listening time with them now, with pop, classical, and especially jazz, and have no regrets at all about my purchase. As a headphone listener for the last 35 years, I think I have enough time in service to recognize a really good set of earspeakers, and these qualify as the very best, including balanced armature and electrostatic cans, with which I've had long listening sessions.(even though I didn't own them: I've got some good audio buddies.) Your mileage may vary, but to my ears, money spent past the three-hundred dollar mark that I spent for the M4Us buys--at best--quickly-diminishing returns. I've got a large head (size 8 3/8), have spent up to four continuous house wearing these cans, and have forgotten I was wearing them--even with my glasses on, something I can't say about other 'phones. Best of all, even with glasses, the seal was so good that there was no perceptible diminishing of bass, so for me, at least, my pleasurable listening hasn't been reduced in the least. Does it sound like I'm enthusiastic about the M4Us? You bet! ### ⭐⭐⭐ 3.0 out of 5 stars Good sound with a sticky touch feeling *by E***U on Reviewed in the United States on February 6, 2018* Excellent sound quality for its price. However, the black matte material on the inner sides of both the ear outer covers are very sticky and currently uncleanable. It feels like the material is melted. I have to wash my hands everytime after touching the headset unless I avoid the ear cover. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/5446046-psb-m4u-1-red-m4u-1-high-performance-over-ear](https://www.desertcart.co.uk/products/5446046-psb-m4u-1-red-m4u-1-high-performance-over-ear) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-31*
