Hear a balanced reference

Neodymium magnets and copper-clad aluminium wire voice coils drive the 40 mm transducers. The headphones cover a 15 Hz to 24 kHz frequency range with tuning intended for accurate monitoring.

Monitor with one ear when you need to

The earcups swivel through 90 degrees for quick one-ear checks. Cushioned pads surround the ears, helping keep your monitoring sound contained during recording. Set the earcups into a comfortable position before bringing the volume to your usual listening level.

Pack down and change cables easily

The folding construction saves space in your bag. Switch between the included 1.2-3 m coiled cable and 3 m straight cable, then use the 6.3 mm adapter to connect to studio equipment.

The Driver System in This Model

The listed driver arrangement is 40 mm. The manufacturer’s stated frequency response is 15 Hz - 24,000 Hz. Listen with familiar speech, instruments and transient-rich recordings while keeping the playback source and listening level consistent. Driver size describes the construction; the full listening result also depends on fit and your audio chain.

Choose the Listening Environment

The closed-back earcups help contain playback and reduce incoming room sound through their physical construction. Fit affects that seal, so place the earcups evenly before you start monitoring. Use a listening level that lets you follow the recording without relying on the headphones to remove every sound in the room.

Which headphone configuration is this?

Audio-Technica ATH-M40X 40mm Closed-Back Studio Headphones. 35 ohms is the listed impedance; choose the exact model rather than transferring specifications from another version.

Is the acoustic design suitable for my room?

The closed-back construction provides passive sound isolation and helps reduce playback spill. Place both earcups evenly to maintain the intended seal.

Do I need a headphone amplifier?

35 ohms is the impedance, but sensitivity, source capability and your desired level also matter. Use a suitable headphone output; higher-impedance models can need more voltage than a phone or controller provides.

What cable or plug is specified?

Gold-plated 3.5 mm stereo connector with strain relief. Use the connection and any adapter specified for this exact model.

Does it include a voice microphone?

These are dedicated listening headphones. Add a separate microphone and the appropriate recording input if your setup needs voice chat or recording.

How should I interpret the recommended audio equipment?

The recommendations offer alternative audio chains. A standalone amplifier needs a suitable analogue source; a standalone DAC needs an amplifier. Keep the normal stereo cable with the matching headphone output.
