Gearank High Notes

Gearank Recommendation

The ATH-M40x appeared on our recommended list for Closed-Back Headphones For Recording Under $100 from March 2016 until January 2022 when it had been out-ranked by other headphones.

It was also on our recommended list for Studio Headphones Under $100 from our first edition in May 2017 until January 2022.


The ATH-M40x offers precise audio monitoring across an extended frequency range with a flat frequency response.

They are engineered with pro-grade materials and sturdy construction and come with a detachable cable and swivel ear cups that make them suitable for one-ear monitoring, which is a bonus for DJs.

Their collapsible design fits well with the carrying pouch, which makes it convenient to take anywhere.

These headphones are built with tight ear cups that provide exceptional sound isolation with minimal bleeding. They are suitable for professional studio tracking, mixing, and monitoring.

These headphones a good choice if you want a light-weight option with a detachable cable that has a flat enough frequency response for monitoring and tracking.

The ATH-M40x is a great pick especially if you've tried the ATH-M50x and feel the bass could be more relaxed. Rest assured, you're not cutting corners too much from it's bigger sibling.
