Audio-Technica ATH-M40x Headphone Review

Support the Sponsor of this Review:

Today I review the little brother to the most popular headphones on youtube, the Audio Technica ATH-M40x. These are very similar to the M50x, but with a flatter frequency response. The only complaints I have about these would be that they get warm over long periods of time, the cable system has a proprietary mount, and the mid frequencies seem to have a slight cut to them. Other than that they are relatively neutral and a decent option if you’re looking for a set of studio headphones.

Buy the Audio-Technica ATH-M40x

Thumbs up for that sponsor clip! XD

Hey Bandrew,

Can you test some wireless Microphone systems. If it is possible, please some condensor mics for chorals. It would be great if the system costs more than 500$ Dollar. Is this possible?

Greatings from Bavaria!

Tom says:

can you do a video for the 7506? I know there’s already thousands of reviews out there for it but we like yours!

Gustavo Murillo Vega says:

Review the 7506, compare them to other headphones. I think they are the best closed at 150 dollars range. And I doubt something with more money will sound that much better. The M40X sound congested, I didn’t like them at all, and even though they have a smaller coiled cable, is more fragile and the headphones themselves even though the earcups are the same size, the headphones themselve are way bigger. I though you could fold them flat, but is not that flat, I prefer to fold as a ball my 7506, is less space. I could sure buy a smaller cable for the m40s but if I don’t like the sound nor the comfort what’s the point.

Πέτρος Τραγουστής says:

yo @podcastage, is it worth to spend 50$ more for the m50x instead of buying the m40x?

czdaniel1 says:

2:26 — Oh, damn. That’s what I suspected. Great review. I cannot believe the number of YouTube reviewers that completely FAIL to mention a proprietary connection. I’m sorry my V-Moda Boompro + AT-m50x (or m40x) plans just fell through.

Murdoch says:



Please review the Focal Utopia Circum-Aural Open Back Headphones next. Looking forward to it.

MrHamit64 says:

Hmmmmm 24 KHZ is good. They should be pretty good. I’ve heard Audio-Technica phones before and they are pretty crisp.

Lovro Sabljak says:

I first wanted to buy the m40x but I decided to buy the m50x insted because of the better build quality and the slightly cleaner high frequencies 🙂 Good video 🙂 Can you please review m20x and m30x soon? 🙂

Planet Tyro says:

oh shit son – we made this exact purchase a few weeks back… agreed very decent.. not outstanding but very decent – worth the price in our book – good review

Lainer says:

This might be me, but I dont think your audio sounds that good.

Sheikh Ji Technical says:

Plz sir talk to me why diffrent roland quad vs duo capture plz

Hreniuc Iulian says:

2:27 What do you mean? Can’t I replace the cable with a normal 2.5 to 3.5 if it breaks or something? Because if this is the case then it’s a deal breaker.

moraed52 says:

how are the highs on these?

SlowFox says:

Had these for 2 years. They’re Great! Had to buy a third party chord though. The ones that came with them were to long for everyday use, like listening to music from a phone, or listening to YouTube while at Starbucks.

Zipo214 says:

Audiotechnica 990x all the way…

reggiep75 says:

I thought my brain was broken as there was rattling in the audio near the end and I’ve just spent the last 3 hours having epileptic fits. Damn I thought my brain was well and truly broken hahaha

HeyItsMeSam says:

Would love to see you review the Senheiser HDR 160, almost nobody has put out a review for them and being someone who can’t stand headphone cables, i think they are the best wireless headphones under $200.

Wyatt Edgecomb says:

I have a pair of these, and my roommate has the m50x’s and having compared them extensively, I agree with what he said about the mids. The m50s also sound a bit smoother overall, and I would prefer them for media consumption, the difference in preference is almost negligible for me (and I have Reinkus Heinz 15″ mainspeakers in my living room.)

Mxdanger Gaming says:

No usb-c? That’s disappointing I would expect they would chose the professional option…

Myrmidon says:

Why did ModMic make you dress up like Dwight from The Office for the promo spot?

Gustavo Murillo Vega says:

review the 7506s! I love them

NOOBandBRO says:

lol, your memes are on point

Try Hard says:

Sennheiser HD 598 Cs or Audio-Technica ATH-M40x?

sɴᴇᴅᴅᴏ / ᴊᴀᴄᴋ says:

only me that gets weird pop sounds when pausing a video with the m40x, please respond m40x users.

doctor frost says:

Tbh I can’t comprehend the lack of versatility for these types of headphones. All proprietary cable work with literally no in-line remote or mic options being sold by audio-technica. Kind of a bummer because it means you need after-market solutions if you want to do something as basic as answer a phone call.

That isn’t acceptable to me. You can’t be a company that makes high-end microphones, high-end headphones, and somehow lack the ability to combine the two at a reasonable price. Amazing headphones for studio use that could also be great headphones for everyday use, but a simple cable remote is what separates it from being just that.

Cameron Chauvaux says:

I’ve got these and couldn’t stand the regular earpads. I got these to replace them.

Strawhat Jaber says:

I want to put a shorter detachable cable for casual listening. Can I buy any kind without affecting the sound quality? Does Audio-Tech make smaller cables?

Daniel Hrvatin says:

how would these go when traveling on a plane ?

Durgesh Kshirsagar says:

Which one would you recommend for long session and comfort. I am confused between Sony MDR 7506 and Audio Technica M40X. Audio quality is not my priority. Comfort is my main focus for long sessions. Thank you in advance!

Sanji ASMR says:

The only reason , I avoid buying them is because of the leather pads, I hate lather pads
The make my ears hot and sweaty , I wish MX40 came with a velour padding!!!

Thomas Lane says:

Just bought these price matched at my local guitar center for 79.99 (Sweetwater had the sale) best 80 bucks I’ve ever spent.

Noah Kramer says:

Now $80 on Amazon

Chicken Man says:

darth_rich says:

You’re really finding your stride now… the channel is going to blow up! <3 Marina

Jonathan says:

I’d get these to keep my ears warm

Beats and Speaks says:

Are you using a PR40 as the mic in this video?

Syed Sarfaraj Amed says:

Awasome video . Thanks for the review. I’m confused which one to chose Audio-Technica ATH-M40x or Sennheiser HD 598 CS Closed Back . May you suggest me which one is better in the same price?

John Doe says:

Hey, thanks for the review. Could you go into a little more detail as to why you perfer mixing with the MDR 7506’s? I’m looking travel and record/edit music on the way. Would you suggest the MDR 7506’s over the m-40x? Thanks again!
