Review on Upgrade Your Studio Gear with Audio-Technica ATH-M40x Professional Studio Monitor Headphones: 90-Degree Swiveling Earcups, Pro-Grade Earpads/Headband, and Detachable Cables by Jagvir Singh ᠌

The basses are collected, elastic, there are exactly as many of them as you need. Highs (especially audible in vocals) are slightly overstated, but they sound very detailed, but the whistling ones stand out. They do not cut the ear, as with other models, as if they were trying to muffle them, as you can hear the stage narrowing at high frequencies, but for me this is a plus, the width of the stage spoils the detail. As a result, such an original solution - a narrow stage, a detailed sound. Used with Fiio X3 II player.
