CMF by Nothing Headphone Pro vs Audio-Technica ATH-M30x

These are two different tools. The CMF Headphone Pro is a wireless, noise-canceling everyday headphone with LDAC, spatial audio and a huge battery. The ATH-M30x is a wired studio monitor with a flat, mid-forward tuning, a 3 m cable and no mic or ANC. Buy the CMF for commuting, calls and travel; buy the M30x for mixing, tracking and editing at a desk. The M30x has the longer track record and far more owner ratings; the CMF packs more modern features.

  • Choose the CMF by Nothing Headphone Pro if you want one wireless pair for commuting, calls and travel, with ANC, LDAC and multi-day battery.
  • Choose the ATH-M30x if you do studio tracking, mixing or editing and want a flat, wired monitor that plugs into an interface.

What reviewers say

CMF by Nothing Headphone Pro

  • 4.4 / 543 ratings

Rated 4.4 out of 5 from 43 ratings, the Headphone Pro is generally well received for its price. Buyers highlight battery life and features for the money; the on-ear fit and ANC strength draw the most criticism.

What people mention
  • BatteryPraisedOwners say they go days or weeks between charges, especially with ANC off.
  • Noise cancelingMixedReviewers find ANC useful on commutes but noticeably behind over-ear competitors.
  • FitMixedThe on-ear design suits some heads and clamps or leaks on others.
  • BuildCriticisedBuyers describe a plastic-heavy feel that is functional but not premium.

Audio-Technica ATH-M30x

  • 4.8 / 5Google Shopping · 1,500 ratings

Owners and reviewers describe a flat, well-balanced sound that suits mixing and editing, backed by a light, durable build. Comfort and value come up repeatedly. The fixed long cable and modest bass are the usual gripes.

What people mention
  • SoundPraisedReviewers call the tuning flat and well balanced, with clear mids that suit mixing and editing.
  • ComfortPraisedOwners say the pads and low weight make long sessions easy.
  • BuildPraisedThe collapsible frame and pro-grade materials are described as durable for the money.

Questions and answers

Which is better for mixing and studio work?
The ATH-M30x. Its flat, mid-forward tuning and passive isolation are made for tracking and mixing, and the 3 m cable reaches an interface. The CMF is tuned for listening, not reference work.
Which is better for commuting and calls?
The CMF Headphone Pro. It has ANC, a built-in mic, Bluetooth and dual-device pairing. The M30x has none of these and needs a cable.
Which lasts longer?
The M30x has years of owner reports and a simple wired design with few parts to fail. The CMF relies on a battery that will degrade over time, though its rated runtime is very long.
Is the CMF worth stepping up to over the M30x?
Only if you need wireless, ANC or a mic. If you work at a desk and want neutral sound, the M30x does that job and the extra features add nothing.
Can I use the CMF for studio monitoring?
It works in a pinch with the 3.5 mm cable, but its consumer tuning and ANC processing make it less accurate than the M30x for critical listening.
Does the M30x work with a phone?
Yes, through its 3.5 mm plug if your phone has a headphone jack or you use an adapter. There is no Bluetooth.
