Customer Reviews

Amazing!
Finally headphones that pump out the sound I want, with the comfort I want, at a price I can afford!
You just can't go wrong with a pair of Audio-Technica ATH-M40fs's on your ears!

If you like balanced high quality sound that exploits every pitch and accentuates every tone, you can get it right here. If you want headphones that don't hurt your head, don't clamp your ears, and provide good isolation, hey! The ATH-M40fs is your baby!
The build quality is fantastic, complete over the ear circumaural design, very professional in style and durability.
I searched all over to find an amazing pair of headphones that wouldn't rip a hole in my pocket, and I found them.

I am extremely happy I chose these. I was on the skeptical side. I almost bought higher priced Sennheisers, but opted not to due to comfort issues and cheap headband construction.
I was worried about sound quality; as I like to hear every vocal and instrument the way it was intended. For anyone who is looking to listen to music at a higher level with a price suitable for the everyday person. These headphones do justice to the Audio-Technica brand!
I use them for listening to all my music and games; high fidelity classical recordings, popular music (Jewel's intricate voice sounds so good with these strapped to your head), occasional video games (I play adventure, mystery, and RPG's).

The bass is accurate, not overdone and not enhanced. Balanced sound throughout. Great for really getting into the music.
Are these the headphones you've always been looking for but thought they didn't exist? Yes, yes they are!
Are they the best headphone ever made? Well, I wouldn't say that. I've never listed to $150.00+ headphones before. So I am sure there are headphones out there that will make these sound lamer than scary movie 3. But I couldn't imagine needing to. Some headphones can cost over $900! I'm not a recording artist, I don't use these to monitor music. And I don't work as a audio engineer. But I am very picky about, well, almost everything! I am an artist of the visual kind. And these headphone produce high enough audio fidelity for most anyone who can appreciate well recorded audio. I do require a high level of quality, I am very sensitive to subtle details in sound. If there is distortion or a small hiss is my audio equipment, I can hear it.
When comparing headphones and speakers, I can clearly hear pitch subtlties, faded or more pronounced background instruments, and other differences.
Besides, even a farmer in good ol' Georgia can appreciate, and have an ear for good audio fidelity.

For me, these headphones are great. They produce sound in a highly respectable manner at the price I am willing to spend. And thats what counts to most people.

Audio-Technica also makes a variant model of these, ATH-D40fs with enhanced bass. I feel some may prefer them to these and find them more suitable for video games, watching certain movies, and those who like that extra thump.

They also make much higher priced headphones for anyone requiring more fidelity. After listening to these I think they are a very viable brand, completely on level with competing against the well known brands of Sennheiser, Koss, bose, Beryldynamic, and Grado.

Nothing short of WOW!
First things first. These are not for kids who wanna listen to all their hardcore screamo death metal at earsplitting volumes. These are not for people who have a 1000 watt sub in their car. These are not for people who take music casually.

These are for recording.

I don't claim to be an expert on what good headphones sound like. I've never had the money to try some 500 dollar audiophile phones. I am a very active musician; I run a studio in my bedroom and my bands practice room. I've been recording in my bedroom for about four years. I use Adobe Audition 2 as my main recording software.

The Audio-Technica ATH M40fs headphones are THE BEST headphones I have ever heard. I'm sure they're not the best in the world. They're just the best I've used, and I'm pretty sure they're the best for the price.

With these headphones I can hear subtleties and nuances that I never believed possible. I can hear breath noise on the flute intro to Yanni's Deliverance. I can hear the bass on Dreamgirl by Dave Matthews without it beng muddy. I can hear the rumbling lows on the intro to The Battle from the Chronicles of Narnia Soundtrack. These headphones are not bassy, nor are they harsh on the mids, they're not overly trebly either. They are very flat as far as I can tell. I love that I can hear all the different parts to music without any of them being over-emphasized.

The downfall to these phones is that they let you hear ALL of the flaws in your own music; it's kind of depressing. If you want to sound like an amazing pro musician just by buying a new pair of headphones...look elsewhere, if you want to hear your mistakes so you can improve, and don't wanna spend a month's paycheck...then these are for you.

The thing that mainly attracted me to these headphones was the frequency range which was wider than the Sennheiser HD 280 Pro's that I originally wanted. On top of that, the price was 40 dollars lower; hard to pass up.

Another feature that makes these worth your while is the Field Replaceable parts. I don't know about you, but I don't have the money to buy a new set of headphones if my cable wears out.

These have pretty good isolation. They won't block as much sound as earplugs but they block enough to keep your sound pretty pure.

If you want to hear your music in a way that you never have then buy these headphones.

If "High Fidelity" is what you are looking for then this headphones is the right choice.
Once the "Hifi Choice" says about this Audio-Technica ATH-M40FS " These 'phones have an uncontrollable desire to tell the truth, the whole truth and nothing but the truth. They quite simply take a piece of music and tell it how it is."

If you want the real "High Fidelity" headphones you should buy this one.

No doubt why this headphones become an industrial standard around the world.
A real competitor of the formidable "Sony MDR 7506 Studio Monitor".

Since I have quoted from a review by "Hifi Choice" then I would like to quote more for the conclusion.

" A pair of good honest headphones, which refuse to add anything to the original recording, yet take nothing away. If you like your music to have that raw, 'straight out of the studio' edge then these headphones are a must. A rockin' Recommended. "
