What reviewers say

Audio-Technica ATH-M40x

Owners treat the M40x as a dependable budget studio headphone with honest, uncolored sound. Most criticism centers on comfort and the stock pads rather than the audio.

What people mention
  • SoundPraisedOwners describe a flat, detailed response that reveals problems in a mix.
  • ComfortCriticisedMany find the clamp firm and the stock pads thin for long sessions.
  • BuildPraisedThe plastic frame and hinges hold up well with normal use.
  • CableMixedThe detachable cable is valued, but it transmits some handling noise.

Questions and answers

Which is better for commuting?
The Sony WH-CH730N. Active noise cancelling, wireless freedom and up to 50 hours of battery suit trains, buses and offices. The M40x isolates passively and needs a cable.
Which sounds more accurate?
The Audio-Technica ATH-M40x. Its flat monitor tuning is designed for mixing and critical listening. The Sony is tuned for everyday music and adds DSEE upscaling and EQ.
Can I take calls on the M40x?
Not practically. It is a wired monitor with no call mic array or multipoint. The Sony has built-in mics, AI-assisted voice clarity and two-device multipoint.
Which lasts longer?
The Sony runs up to 50 hours with ANC and 75 without, and a 3-minute charge gives 60 minutes. The M40x has no battery to run down, but its cable and pads wear over time.
Is the Sony worth it over the M40x?
If you need wireless, ANC and calls, yes. If you mix or monitor and already have a wired setup, the M40x covers that job the Sony cannot match.
Do both fold for travel?
Yes. The Sony swivels and folds compact; the M40x has collapsible earcups with 90-degree swivel. The Sony is lighter at about 207 g versus about 240 g.
