Merging acclaimed features of the M-Series headphones with a foldable, travel-friendly design, and one-ear monitoring capability, the black Audio-Technica ATH-M40x monitor headphones offer pro-grade build quality and audio performance for studio-based production, location recording, DJing, and daily listening. Outfitted with 40mm dynamic drivers and an over-ear, closed-back design, the ATH-M40x headphones deliver a flat, accurate response and wide bandwidth (15 Hz to 24 kHz) while isolating you from outside sounds.
Thanks to the 90° swiveling earcups, pro-quality materials, and generous cushioning on the headband and earpads, the headphones are both durable and comfortable to wear. Two detachable, single-sided cables—one coiled and one straight—are included for optimal operation in the studio or on the go. Each cable sports a gold-plated 3.5mm mini plug for use with mobile devices and computer soundcards, and a 1/4" screw-on adapter is included for easy hookup to audio interfaces, mixers, and stereo receivers. A carrying pouch is supplied with the ATH-M40x for convenient storage and transport of the headphones.

Audio-Technica ATH-M40X Overview
40mm Drivers
The ATH-M40x features 40mm dynamic drivers with rare earth (neodymium) magnets and CCAW (copper-clad aluminum wire) voice coils for high-quality sound reproduction.
Tuned for Flat, Accurate Response
The drivers and headphone design work together to provide a sonic signature tuned flat for accurate sound monitoring across the entire frequency range. With a frequency response of 15 Hz to 24 kHz, the ATH-M40x can reproduce a full spectrum of tones.
Over-Ear, Sound-Isolating Design
The ATH-M40x utilizes a circumaural design that contours around the ears for excellent sound isolation in loud environments. This over-ear, closed-back style is optimal for reducing bleed and separating you from outside sounds.
90° Swiveling Earcups and Foldable Design
Equipped with 90° swiveling earcups, the ATH-M40x ensures a great fit and allows effortless one-ear monitoring, a welcome benefit for DJs and singers. The earcups fold up to meet the headband, saving space during storage. A carrying pouch is supplied for protection and convenience while transporting the headphones.
Two Detachable Single-Sided Cables
To expand its versatility, the ATH-M40x incorporates a detachable cable design that exits from the left side. This enables convenient cable swapping and makes it easier to distinguish the different sides of the headphone. Two cables are included—a 3.9 to 9.8' coiled cable and a 9.8' straight cable.
3.5mm Plug and 1/4" Screw-On Adapter
The attached cable is terminated with a gold-plated 3.5mm TRS mini plug for easy hookup to mobile devices, MP3 players, and computer headphone jacks. A secure 1/4" screw-on adapter is included for compatibility connectivity with audio interfaces, mixers, and dedicated headphone amplifiers. Built-in strain relief on the 3.5mm mini plug reduces the likelihood of damaging the connection if the cable is pulled.
Pro-Grade Build Quality
Thanks to the pro-grade earpad and headband materials used in the ATH-M40x, the headphones provide increased durability and comfort while delivering enhanced audio and effective isolation.

Audio-Technica ATH-M40X Reviews
Great for Stream Mixing!
By Brad
Rated 5 out of 5
Date: 2026-04-26
We purchased these to complete our online stream mix station. We are very happy with the balance from these headphones, allowing us to produce a pure mix. We are retrieving our sound with an HDMI audio extractor, so we also had to put a headphone amp inline, which really completed the package.
Super Solid Set of Cans

I'd been looking for an affordable set of headphones for awhile, and after reading many reviews, decided to go with M40x. After only having a set of wired Apple ear buds for years, I've been super happy with the decision! I've been working in Ableton Live and these let you clearly hear very small changes in audio when playing with audio effects and twiddling synth knobs. The over the ear style is also great for blocking out external noise. Even casual listening is fantastic with these, with solid bass sound. Very happy to have picked these up at a great price for a B-stock pair that came essentially brand new. Highly recommended!
