The unit balances low distortion against bass reproduction, so 5 Hz – 80 kHz is more than a number on a spec sheet.

New reference closed monitor headphones for creators with ultra-wideband playback. The Sony MDR-M1 Studio Headphones are high-quality, professional over-ear headphones designed for accurate sound monitoring. Featuring plush ear pads and a lightweight design for comfort during long sessions, they deliver a flat frequency response, making them ideal for music production, mixing, and mastering. With durable construction and swiveling ear cups, these headphones provide both reliability and convenience for studio environments.
A 40 mm driver running from 5 Hz to 80 kHz, with a closed design that shuts the room out. For tracking and mixing where nothing outside may reach the monitoring.


The soft, thick pads are built for long sittings and can be replaced once they wear out, so the headphones do not reach end of life with flattened foam.

A short 1.2 m for the desk and a long 2.5 m for the room, both detachable. The screw-on adapter takes the mini jack up to 6.3 mm.
The closed acoustic chamber with effective isolation allows accurate judgement even in rooms nobody built for listening — a rehearsal space, a location, or right beside running equipment.
The unit balances low distortion against bass reproduction, so 5 Hz – 80 kHz is more than a number on a spec sheet.
Sensitivity is enough for a recorder output, and the impedance suits studio headphone amplifiers.
Headroom for signal peaks, so the driver never runs up against its limit.
The tuning was worked out with working engineers, so the headphones reproduce the creative intent rather than a colour of their own.
Studio sound, unleashed
Ultra-wideband playback and a closed acoustic structure with high sound isolation allows for detailed and precise monitoring, for a wide range of audio production workflows.
