Sony MDR-M1

Overview

The Sony MDR-M1 is Sony’s modern closed-back studio headphone, considered the successor to the iconic MDR-7506. It targets producers, engineers, and creators who want accurate, reliable sound and comfort for long sessions. It features a 40 mm dynamic driver with a neodymium magnet, 50 Ω impedance, and a wide frequency response rated at 5 Hz – 80 kHz. It also comes with detachable cables (two lengths), replaceable parts, and design improvements aimed at reducing listener fatigue.  

Pros

1. Wide frequency range & clarity
   The extended response (5 Hz up to 80 kHz) means you get more information in both the sub-bass and ultra-high regions. While some of that is beyond human hearing, it helps with transient detail, clarity in high-end content, and gives the overall sound more “air.”  
2. Good isolation & closed-back design
   Because it’s closed-back, leakage is minimized both in and out. That makes it well-suited for tracking, overdubs, and recording in environments where bleed is a concern.  
3. Comfort & usability for long sessions
   It’s lighter (≈ 216 g without cable) than many comparable studio headphones, has soft ear pads, and includes two detachable cables of different lengths (a shorter and a longer) for flexibility depending on whether you’re mixing at your desk or tracking further away.  
4. Repairability & replaceable parts
   The pads and cables are replaceable, which is great for long-term usage. This means less waste and more longevity. 

Cons / Trade-offs

1. Sound signature & neutrality
   While it aims for neutrality, some users note that it is less “colorful” or less flattering than more consumer-oriented headphones. The mids may feel more restrained compared to headphones that emphasize warmth or character. If you want huge coloration, this might not give it.  
2. Warm-ear potential
   Because the closed design and padding are cushioned and snug, over long sessions especially in warm environments, you may notice more heat build-up around the ears. Not unusual for closed backs, but something to consider for marathon mixing or tracking.  
3. Cable lengths & portability limitations
   The inclusion of two cables gives flexibility, but both are straight and there’s no coiled option. Also, while the headphones fold somewhat, they aren’t ultra-compact for travel. If you often carry gear around, portability costs are a factor.  
4. Price vs incremental upgrades over legacy models
   For those who already have MDR-7506 or similar, the improvements are real but perhaps not dramatic enough to make the switch unless you value the newer driver, better isolation, detachable cables, or the upgraded fit and components.

Best For

• Producers, engineers, or artists who do a mix of tracking, overdubs, and mixing, especially in less than ideal acoustic spaces, where isolation and bleed are issues.
• People who value comfort for long sessions and prefer headphones that stay usable over many hours.
• Home studio users needing accurate monitoring, but who don’t want open backs due to noise issues.
• Anyone who wants sustainability (replaceable parts) and flexibility (different cable lengths) built-in.

Summary & Verdict

The Sony MDR-M1 is a modern, polished reimagining of Sony’s classic studio headphones that addresses many of the drawbacks of earlier models. It delivers extended frequency response, good build and comfort, improved isolation, and better usability (detachable cables, replaceable parts). If you need a workhorse headphone that can handle serious studio use without being burdensome, this is a strong candidate.

Verdict: Highly recommended for music production, especially for users who want accurate, reliable headphones that hold up well wear-and-tear and long hours. If you come from older Sony models, this one is worth considering as a solid upgrade.
