Version 1.0.0

Sound Quality

With a V-shaped sound signature, the MDR‑M1 emphasizes tight, controlled bass and present treble, while keeping the midrange clean yet forward. The wider frequency response vs. the MDR‑7506 delivers improved clarity at both ends of the spectrum without being overly bright or fatiguing—making them ideal for immersive long sessions

Build & Design

The MDR‑M1 weighs in around 216 g, making it lighter and more comfortable than the MDR‑7506. It features robust construction, improved padding, foldable ear cups, and threaded detachable cables (two lengths included), all designed for studio wear and easy maintenance

Features

  • Closed-back, over-ear design
  • 40 mm dynamic drivers with ultra-wide playback
  • Frequency response: 5 Hz – 80 kHz (JEITA)
  • Impedance: ~50 Ω
  • Two detachable straight cables (1.2 m and 2.5 m) with screw-in connector
  • Fold-flat ear cups and replaceable earpads for durability and transport
  • Lightweight (~216 g)

Price & Value

Retailing around $250–$270, the MDR‑M1 sits above entry-level models like the MDR‑7506 but well below ultra-premium reference headphones. Considering the comfort, build quality, and neutral tuning, they represent a strong value for serious producers and studio professionals

Pros

  • Extended frequency range (5 Hz–80 kHz) delivers more detail
  • Balanced V-shaped signature keeps sessions fatigue-free

Cons

Perfect for producers, mixers, and engineers who demand comfort and clarity in a closed-back form. If you’re upgrading from popular models like the MDR-7506 or seeking reliable studio headphones that last, the MDR-M1 is a worthwhile pick.
