1 / 11The wired ATH-M50x: still good.
A 3.1 puts its noise isolation in the bottom quarter of over-ear headphones we've measured.
Measured on 87 of the 239 we've cataloged.
Wired-3.5mm is the most common — on 48% of the 238 over-ear headphones we've cataloged (of 239).
above average for over-ear headphones — based on 197 of 239 we've cataloged.
Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

Once the best choice in the ATH-M line, the ATH-M50x is still a good choice for casual listening and recording audio. With its three cables and proprietary connectors, it's a mixed bag, especially compared to the Bluetooth version and the ATH-M40x. Find it at the right price and you won't regret it for the good sound, but these days it's an awkward sibling.
