1 / 10An unglamorous set of workhorse studio headphones for well under $100 that belongs in your studio.
A 3.8 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).
below average for over-ear headphones — based on 195 of 240 we've cataloged.
The Audio-Technica ATH-M30x is a great choice for anybody that needs a decent set of over-ear studio monitors. While the frequency response is not totally spot on, it works for basically every situation reasonably well. The sound quality and reasonably good comfort promote its candidacy as a great pick for $69 USD.

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.
