Audio-Technica ATH-M40X Professional Studio Monitor Headphones

The Audio-Technica ATH-M40X is a professional closed-back monitor headphone tuned with one priority: a flat, accurate frequency response. This is the headphone for mixing engineers, content creators, and anyone who needs to hear the recording exactly as it is — not colored or hyped.

Why flat response matters: Consumer headphones boost bass and treble to make music sound exciting. That's a problem when you're mixing, because the boost masks issues that show up on other speakers. The M40X gives you neutral, honest sound — if your mix sounds good on these, it'll translate to other systems.

Specifications:

• 40mm large-aperture drivers with rare earth magnets
• Closed-back, around-ear design — high isolation from outside noise
• Frequency response: 15 Hz – 24 kHz
• Impedance: 35 Ω — drives well from phones, laptops, and audio interfaces (no headphone amp required)
• Sensitivity: 98 dB
• 90° swiveling earcups for one-ear monitoring
• Detachable cables: 1.2m – 3.0m coiled + 3.0m straight included, plus 1/4" adapter
• Collapsible design with carrying pouch

Ideal for: Home studio mixing, podcast editing, content creation, video editing audio review, DJ monitoring in quiet environments. The M40X is the smart choice if you can't quite stretch to the M50X but want the M-Series accuracy.
