    ATH-M40x Professional Monitor Headphones 4.6 5 8 8
    Great But Lacking in design and durability. I loved these headphones with all my soul but the rotation of the cups are a little weird. Mine recently broke when the right cup got stuck and i was the plastic holding it together broke off. I could not believe it because i barely put any force into it. if you pick these up and rotate the cups the wrong way they can break off fairly easily. Im in the process of claiming my warranty but even tho i love the M40x im scared of the fragile design. Im most likely gonna trade my new pair in or sell them to work for a pair of M50x or M70x. May 26, 2015
    Awesome but quite big These headphones which I got about a month ago have been amazing, they are clear and reproduce sound without harshness at higher volumes(after the first week of using them) and are very comfortable despite being quite heavy compared to other headphones April 15, 2015
    Great phones! i am a music teacher and DJ. I use these phones for when I record my students, run sound for concerts, and occasionally when I do dances. First off....the sound quality is unbeatable!! Very true flat phones. I have cranked the volume very loud with no distortion and you are able to hear everything! The padding on the cups get a little warm but nothing that can't be ignored. The isolation is great....and did I mention the sound quality! Unbeatable in a headphone at this cost!!! the plastic makes me a little nervous, but it hasn't broke yet (after 9 months of wearing ALOT) March 18, 2015
    Great headphones at a affordable price! As a college student i routinely listen to music, play video games on my computer, and audio edit videos. From the 100+ hours of using this product i can say without a shadow of a doubt that these headphones are worth every penny they cost! These headphones have gone head-to-head with other headphones, costing several times more, and have stood their ground. The only drawback i can think of would be that the headphones will occasionally pick up a small buzzing sound from the impedance of your computer system, which can easily be fixed by a digital-to-analog converter. March 16, 2015
    The Best for What I Do!!!!! I'm a Producer/Songwriter from Chicago, IL and I could've spent hundreds of dollars on a pair of any competing set of studio headphones but I took a chance on Audio-Technica because I love your condenser microphones. So when I ended up purchasing the ATH-M40x, I knew they were part of the latest series but didn't expect much in lesser price range.....I ate those words immediately after I took a listen to some of my favorite songs as well as my own mixes. I love the fact that I can be so confident in such a reasonably priced pair of headphones for general listening as well as tracking and mixing to the point where i'm making people that don't make music at all go buy a pair as soon as they hear mine. The 40mm drivers are EVERYTHING, amazing flat response, simplistic design & the included leather carrying bag has been such a big help. I went through a short period where I was creating and mixing tracks with no monitors and all I had was a cheap interface and the ATH-M40x's. As it turns out, when I play my mixes for actual engineers, they're incredibly impressed and always say things like "you know, it sounds perfectly fine just the way it is". These have been my life-line and will continue to be a part of my mobile setup. I will eventually get a pair of M70x's however, I will always keep these at bay just in case. Thank you Audio-Technica and continue to make dope products. March 12, 2015
    awesome way better than beats or any other overpriced garbage headphones, quality build and audio very impressed. only problem is the extremely long cord..although i can't really complain about it because these are meant for studio use, but it would be nice to have a "normal sized" cable as an option. other than that i love them. November 16, 2014
    Excellent return on investment here I am a very experienced headphone user of many years. Currently I own a few sets of very expensive headphones and a nice home headphone amplifier. I will admit that I purchased the M40x not expecting to be very impressed. Well I am extremely impressed. The headphone is comfortable and the overall sound signature is slightly warm and balanced with very well extended, but non-sibilant or fatiguing treble. The sub-bass isn't that pronounced, but it is certainly adequate and the emphasized mid-bass gives the music an engaging quality. The M40x does a commendable job with instrument separation and detail retrieval. I also find the bass response fast, but there is enough decay that the notes last long enough to sound natural. I listen to a great variety of music with an emphasis on well recorded material, but even with hot mastered rock and pop the M40x felt poised and articulate; far more so than I expected and in my mind, more than a reasonably priced headphone should. You certainly could drive it well enough with the output from a phone or a DAP, but it scales very well and benefits from adequate amplification. When I drove the M40x from my home system which has a very good DAC and amp I was very impressed with the performance finding the sound signature very good even when compared against my considerably more expensive orthodynamic headphones.

    Best headphones in the bang for buck ratio! Audio-Technica's ATH-M40X headphones are my all time favorite headphones. These are the new and improved versions of Audio-Technica's ATH-M40/FS/45 and other older M40 headphones. These are just as comfortable as the ATH-M30s but with nicer padding on the cans and bands and are mostly made with metal and plastic. These come with two cables one 9 foot one for home use and a 4 foot for portable use. These headphones have the best sound quality that can be compared to headphones costing 300 dollars or more. These headphones are flat sounding meaning that all lows, mids and highs are brought out evenly and superbly. These M40Xs bring out all the subtle details in music that most headphones can't produce. An example would be the acoustic guitar in rock bands that no one hears. These are fantastic with every genre and I love the nice studio sound they give with well done detail and separation of all the instrumentations and voices. These, even at the highest painful volumes, create no feedback or distortion. I highly recommend these to everyone who loves music. April 13, 2014

    Answer: 
    Greetings josh25;

    To simply put it the base on these headphones are not boosted. So depending if you prefer to listen to the audio file that the producer heard or have it boosted this can be a good or a bad thing, but in general the base on these is great and not overpowering.

    the difference in price between the ATH-M40x and the ATH-M50x is due to:

    -larger drivers

    -wider frequency response (even tho it goes further than what a human can hear which is usually between 20hz-20khz)

    -an extra cable

    -a better carrying case

    -180 degree swivel instead of a 90-100 degree swivel

    Hopefully this answered your questions.

    Answer: 
    I own the earlier version of the M40. It is most definitely tuned to be quite flat in response compared to the M50's slight V-shape sound signature. And by flat, I mean a real flat EQ. Very nice tool if you need this kind of response for your applications. The M40 is a favorite of my father since he uses it primarily with his guitar.

    The M40 will need EQ if you want to achieve extra bass with the headphone.

    I can't really put a figure on what pieces dictates price...but in the process of stepping up from the M40 and M50, a few things are highlighted:

    -You go from a 40mm driver to 45mm driver. The larger driver can easily hit the lower frequencies with a bit more more pressure as the driver can displace a bit more air. As such, the M50 can actually output low frequency effects with significant presence as you can feel the sound pressure going into your ear...similar in effect of a 10" Subwoofer sweeping through 38Hz-50hz test tones while shattering windows LOL But it's because of this effect that a lot of drummers out there prefer the M50 model.

    - Wider Frequency range but more importantly you go from 98dB to 99dB sensitivity. The M50 are more sensitive and will require less power to achieve the same listening volume.

    All in all, try auditioning them if you're able to.

    Answer: 
    Bass resonse on the ATH-M40x is comparable to the M50x, but not the same. The ATH-M50x will generally have "slightly" more low-mids. Audio-Technica will not comment on pricing.

    Is this a vegan headphone?

    I would like to confirm that this headphones are leather-free.. I also read in other website that they come with a leather carrying pouch. Is this right? I am vegan and trying to buy a non-animal product. Thank you.

    Answer: 
    ALL Headphones sold by ATUS (Audio-Technica United States) are vegan-friendly except the following:

    ‚ÄĘ ATH-CKW1000ANV (leather case)
    ‚ÄĘ ATH-W5000 (leather earpads)
    ‚ÄĘ ATH-W3000ANV (leather earpads)
    ‚ÄĘ ATH-ESW9A (leather earpads)

    The non-leather material we use for the ATH-M40x headphones is made with a vinyl-based or polyurethane-based material that we refer to as ‚Äúleatherette‚ÄĚ. The carrying pouch for all M-Series headphones (including the ATH-M40x) is also vegan-friendly.

    However, since you are located in the United Kingdom, please direct any future questions towards the Audio-Technica division in Europe:

    I recently purchased and found with my Samsung Note 2, I need to increase my volume almost close to max to get nice sound level which I enjoy VS my Dell laptop which is actually producing very nice sound and crisper sound even and mid volume setting of my laptop

    Can you kindly help me understand the impedance and sensitivity settings ? and cause for same.

    I purchased this product after seeing great reviews about ATH M40x. FYI I still enjoy the sound :) but was little upset with low sound with my Samsung Note 2

    Answers

    Answer: 
    I am also using Note 2 with M40x as well as Status HD1. I have the same issue with the volume. From the reviews on driving headphones via hand phone, general consensus is 32ohm is about the max phone can drive.

    I am now using a free apps player call NRG. It has a "pre-amp" function that allows the output to be increase. So far only downside is it seems to use more juice from the phone's battery. Luckily I am using "zero lemon" battery which is 3x (9300mha) the capacity of original Note 2 battery (3100mha). Down side of using this battery is u can only use the back cover that comes with the battery & it is bulky & heavy.
