  • Overview

    The ATH-M40fs has been discontinued and replaced with the ATH-M40x Professional Monitor Headphones.

    Audio-Technica’s premium professional studiophones offer a flat, extended frequency response for professional studio monitoring. Superior components provide very high SPL capabilities while maintaining exceptional clarity of sound. Exterior design features include sturdy strain-relief cable and comfortable circumaural earpieces that can be rotated 180º to permit one-ear monitoring. The studiophones utilize 40-millimeter drives with neodymium magnets and copper-clad aluminum wire voice coils for lowest mass. They are equipped with an 11-foot cable terminated in a standard ¼-inch connector. This field-serviceable model allows elements, cables, and earpads to be replaced in the field if needed.

    Audio Technica is the choice of professionals!!

    I use these headphone in my home recording studio. I have had zero problems and would recommend them to everyone, for any level of use!

    Solid Choice

    I was in need of a good set of headphones specifically for tracking and I decided to try the ATH-M40fs. The build quality is extremely solid, I especially like the spring-equipped 1/4" connector. There is plenty of cord length and the closed-back design minimizes bleed when tracking vocals. They are very comfortable on and the soft material over the ear cups is a nice touch. Since I only use these for tracking the sound quality is perfectly adequate for my needs. Overall I believe this was a solid purchase.

    Incredible response and comfort at a low price!

    With poser 'designer series' headphones flooding the market for kids to spend their dollars on, I have found incredible performance and comfort in the ATH-M40fs studiophones. Whether plugged into our band's mixing board, into my stereo, my laptop or my smartphone, the sound reproduction excels, and compares to no other. Whether listening to a live mix from our 7 piece MoTown band, screaming trumpets in a big band recording, pipe organ compositions, barbershop quartets and chorus', or more modern selections, every last bit of every sound is brought to my attention. Even some selections that I have listened to several times prior reveal nuances previously missed by other headphones. I do highly recommend these superb quality studiophones as a smart purchase over others costing two or three times more! They are solidly built, and you can count on them to provide better sound than most anything else available. Sincerely, Andy Platz trumpet player for The Swizzle Stick Band, Akron Ohio

    Great sound for a fair price

    My M40's have served well as everyday headphones in an office environment. They are durable enough for everyday use without worry that they will be damaged. The audio quality is superb, with a near flat response. They have a warm quality to the sound while preserving the integrity of original recordings. These headphones are fairly comfortable for all day/extended use or wearing. The only downfalls in my opinion are that they come standard with a 1/4" plug and no adapter. It is expected that studio headphones would have this feature, however some of A/T's other headphones in their studio line come standard with an adapter as well as multiple cables to be used in different scenarios. For the money, these are a great value. As stated above, the main issues that I see have to do with portability and not practical usability.

    Electronic Drums

    I've had these for 6 years of nonstop use and everything is intact and working well. I use these with a Roland V Drum kit. The low end reproduction in the headphones makes the kick drum sound meaty while maintaining the mids and highs from low to high volume. I mix music and the drums similtaneosly in the headphones and it performs like a beast. The closed back design helps with some sound isolation too. I only wished it came with a detachable cord that allowed you to plug into either ear.

    GREAT product

    I use them with a focusrite scarlett 2i2 soundcard and they sound great! just great!!!! the output power of the soundcard is pretty high but this ATH-M40fs handle it with no problem ; bass, mids,treble are played as it should be. Great build quality! I just got them and listened all kind off electronica music(d&b,progressive,etc) and i am very happy that i chose them. Also they are very comfortable to wear. I hope that i won't have problems with them beacuse i trust in Audio-Techinca quality. And one more thing : i think is the best quality/price balance for professional headphones with this technical specifications.

    Very Reliable

    I can rely on these headphones whenever I compose music or simply want to listen to the nuances of music that I cannot capture elsewhere. They maintain a strong bass when harmonies become complex and allow the listener to focus on specific melodic lines while still perceiving the music as a whole. Comfort is excellent for what they are meant for and the superior sound quality has remained undiminished over several years. They work flawlessly with my keyboard. An adapter will normally be required for casual listening on computers. Excellent headphones.

    Great for mixing and monitoring

    I bought mine at least 6 years ago. I record and mix my own records. They are very comfortable...I have easily put 1000's of hours on these. They're durable, comfortable and accurately represent my mixes to other sources truthfully. Once I get a mix that sounds good with these headphones, they sound great on every other source. I know that mixing for long periods of time are a no no, but I can go hours without ear fatigue. I will buy another pair just to use at home and take the ones I have on the road for listening pleasure as well. One of the few products that I have that I feel like, "they do make them like they used to." Buy them, they're a no brainer!

    The M40fs are pretty sweet. They look kinda bulky, but they're actually fairly light. The audio quality is also very nice for the price. I also love the 1/4" plug so you don't need an adapter to use them with your equipment. Buy these if you're on a budget and you still want quality sound, you won't be disappointed.

    I just wanted to know if I can use these to listen to music on my phone and laptop, with and adapter or will the ohms be to high?

    aslighting

    Thank you for your inquiry. These will work with your laptop or iPhone. You will need a 1/4 inch to 3.5 mm adapter.

    I use them with great results in both my laptop, and in my smartphone even through the phone case.

    I don't mean to dis you, but did you verify that the balance is set to the center, between left and right? Make sure too that the plug is fully inserted. Thanks!

    Jazzman42960

    How do I replace the audio plug at the end of the cable? How do I replace the plug at the end of the cable? I need to know which color wire to solder to which terminal on the replacement plug.

    flairpup

    Black or copper (untinted): ground (shared between left/right in case of a single-entry cable). Solder both left and right ground wires to the ground sleeve in case there're two separate channel cables. Red: right. Usually right flap seen with the plug pointing upwards, though this can be different for some plugs. Blue or green: left. Try with wires connected to the plug without soldering first, as some plugs may exchange left and right flaps. Sometimes the longer flap is right (and it could be leftmost).

    Are these headphones good at keeping outside sound out? Like when i am doing a drum cover and i want to be able to hear the recorded drums well enough to be able to hit all of the notes on time. Do these headphones have good sound reduction?

    Tombo

    Thank you for your inquiry. These headphones do have a degree of passive isolation and have been use in studios for many years. Please note they do not have active noise canceling circuitry. I doubt they will keep out the sound of your drums, but they should reduce it enough to allow you to hear your recorded music.

    AudioSolutionsManager

    I do find that they reject quite a lot out outside sound, but not 100 percent.

    Jazzman42960

    Short answer: that depends on your headphone amp's power. Long answer: ATH-M40 have hollow cups. There're no baffling or isolation materials in there, unfortunately. But you can improve isolation fairly easily by coating cups from the inside with Dynamat, then Blu-tack. Then sticking something like felt, plied cotton, or fibrefill on top of the Blu-tack layer (to compensate for slightly decreased cup volume and improve isolation a bit more). Dynamat and Blu-tack are both vibration killers. In other words, they make an excellent isolation improvement by decreasing cup vibration in response to external noise. You can also do the same coating on the back of the drivers to improve stability, though you'd have to make sure any venting holes aren't coated.

    Where specifically can I buy a 1/4" female stero to 3.5m stereo male adapter? I would like to buy a 1/4" female stero to 3.5m stereo male adapter for my athm40fs, could you let me know a couple places that I can specifically find these?

    misteracer

    electronics stores like radio shack usually have those in the store somewhere. if not then you can always get one online.

    Are there different types of replacement ear pads available? I really like that these are field serviceable. But I was wondering if there is the option to by a nicer set of ear pads, like the kinds used for the ATH-M50s.

    Thank you for your inquiry, The supplied ear pads are the only ones available. There are no upgrades.

    where do I get a field replacemt cord? these a great phones, I have two pair, but need to replace the cord on one pair...I hear all about how these are a snap to fix with the replacement kit, but not one word about where to get one...there's a little wiring block inside the main headphone, and the wiring, (all colored) can be replaced easily, but the quarter inch male jack is non repairable, and that's where the problem is...anyone out there know where to get a kit that will work on this headphone? Help!!

    Which 1/4" F to 3.5mm M adapter does AT recommend? I'd like to connect my ATH-M40fs headphones to a PC. I believe this requires a 1/4" F to 3.5mm M adapter. Does Audio Technica recommend any particular adapter? Thanks!

    bennybenben

    they don't recommend any specific type of adapter i believe. they are all for the most part the same and serve the same function equally well. i have an adapter for mine but i don't use it because my sound card has a 1/4" slot for my M40fs headphones. if you are really into music it's probably worth getting a sound card that supports 1/4 inch input. i hope this helps.

    lolllll117

    Thank you for your inquiry. We really have no recommendation. Make sure your adapter is a 1/4 inch female stereo to 3.5m stereo male adapter.
