1 / 11The wired ATH-M50x: still good.
A 3.1 puts its noise isolation / ANC in the bottom quarter of over-ear headphones we've measured.
Measured on 86 of the 240 we've cataloged.
Wired-3.5mm is the most common — on 48% of the 215 over-ear headphones we've cataloged (of 240).
above average for over-ear headphones — based on 195 of 240 we've cataloged.
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.

Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
