Review: these are supposedly used in all the studios in Asia where people know what a good pair of headphones should sound like - I have been using a well broken-in pair (and much reviled by the headfi.org crowd) of Koss Pro4AAAT for some now. I wanted to try something new and bought these. My decision was based on several factors. These have rave reviews everywhere. I recall reading a post somewhere that the midrange these headphones produce is "magic". But it is more than having been reviewed by golden-eared kids on headfi.org - these are supposedly used in all the studios in Asia by real professionals who make the music that we listen to, and they should know what a good pair of headphones should sound like. These headphones are also considered by many to be superior to the popular highly regarded Sony 7506 headphones. I listened to a number of studio monitor headphones but I never heard Sony 7506. I owned a very similar model, a highly rated Senal SMH-1000, and I gave it up because it sounded too abrasive to my ears. Anyway, Sony MDR-CD9000ST is a very good looking pair of headphones, except for that cheesy 80's "for digital" sticker, as if someone still makes headphones strictly for analog music. The headphones are slim and not overbuilt, but the fit and finish is excellent. They are very light and comfortable. I could keep them on for hours. Compared to these, my Koss headphones feel like two bricks squeezing my head, although I am used to it. But the sound did not impress me. The sonic signature was similar to the Senal headphones, except that the sound was much more delicate and refined. Still, to me the headphones sounded "zingy", "hissy" and "wispy" - bright, sibilant, lightweight and thin. I listened to the headphones for about 20-30 hours and nothing seemed to change. I really wanted to keep these but I like what I like so I am going to have to give them up and go back to my Koss phones. Although I did not care for their sound, I am still going to rate these five stars, because these are very popular professional quality headphones that have their purpose - maybe the studio mixes created by using them turn out to be superior? Unfortunately, only a few models of headphones are available locally to be auditioned, and they are typically the least expensive ones. So we end up relying on amateur reviews to make purchasing decisions. These reviews really don't mean much, because we all have our individual preferences. The self-professed experts throw around terms like soundstage, bass quantity, treble extension, and whether there is a midbass hump or a low treble suckout. You can read stuff like "V-shaped dark presentation" and similar nonsense. Manufacturers would probably laugh if they read some of those reviews. What matters the most to me is how the headphones are voiced. I like gorgeous, fleshed out tones. When I hear an instrument, like a piano or a violin, I listen for the body and texture of the sound. When I hear a drum, I want to feel the energy of the impact. My advice is to listen to these before buying.
Review: "For Digital" - I purchased these because of how fond I've been of my MDR-7506 cans- I had done a bit of research that basically indicated to me that these were a tinge more warm and colorful than the MDR-7506's extremely clean and neutral presentation- this is true! These were introduced to market in 1988 and are visually adorned with marketing that says they're "For digital"- my speculation is that these headphones are tuned a little warm to compensate for the shock many listeners would have had going from the warmth and subtle ambiance in analog music to the comparatively sharp and fuzz-less digital sound on the newfangled CDs of the time. If that was the intent, I would say it was a success! These add a layer of color and a light warm roundness to digital music, without making big sacrifices in terms of accuracy and technicality. Compared with the MDR-7506, I would say they have a slightly narrower soundstage and are minimally less technical, but with the tradeoff benefit of that endearing extra warmth and character. I would use the MDR-7506 if accuracy was top priority, but these have less capacity to become fatiguing for long listening sessions and breathe a different sort of life into digital music. On the physical end of things, they're thankfully built Sony studio-tough. Worth noting, these came with a 1/4 in jack and no 3.5 adapter, so if you're planning on interfacing with more modern consumer electronics, you'll likely want to grab an adapter separately. Clamping force is not excessive but perhaps a bit more than on the MDR-7506 (can't say this definitively as my 7506 cans have had a nice headstart breaking in). The MDR-7506 has a longer cable but is more managable due to it being coiled- I've found I need to shorten the cable on these using an easy rubber band solution. Earpads are a refurbishment you should plan on making at some point, as the crumpled pleather is notorious for turning nasty and flaking out over time. All in all, these are great! The MDR line from around this time earned their reputation as spectacular all-time monitors- the biggest compliment I can pay these is that every time I listen to them, I can't believe how great they sound for how old they are, technologically.

## Questions & Answers

**Q: are these compatible with iphones (5 or 6) and samsung galaxy phones?**
A: These are true studio monitor headphones! They have no inline controls and a long, straight, somewhat heavy cable with a heavy metal 1/4" phono connector. So, although they will work with ANY phone, they are not the best suited to portable use. They don't fold up and you'll need an adapter to plug them into your phone (they don't come with one, or anything else for that matter). They also have fairly flat frequency response; for most people this is experienced as cold, "sterile" sound with not enough bass! If you are set on these, might I suggest the MDR-7506 model. They are almost identical physically, but fold up, have a coiled (but still heavy) cord and a "warmer" more pleasing sound. They also come with an integrated mini phone adapter (just unscrew the 1/4" connector!) Still, not the most portable and no inline controls, but you'll save some money and probably like them better.

**Q: Is it possible that after 10-hour flight bass become weaker? Thank you.**
A: Weaker? No. I have owned 3 pairs in my life over the last 2 decades. Highly doubt this will happen in a 10 hour time period but over time, the pads can flatten and therefore the drive becomes just a half-millimeter to one millimeter closer to your ear causing it to sound like there is less bass and more prominent mids and highs. I say this because when my pads deteriorate over time and I've bought new stock pads, It sounds like the highs become slightly recessed making it sound like there is more bass.

**Q: I'm looking for a case for these, can anyone give a reasonable recommendation?**
A: No

**Q: Are the legit ones Made in Japan?**
A: Yes

### ⭐⭐⭐⭐⭐ Review
*by M***L on June 12, 2022*

There are allot of new amazing headphones out there, all with 'promises, promises'.. The MDR CD900 ST are the last of the loved MDR red band models.. 'They don't build them like they used too !!'.. Yes they do... these are it. 'There has to be a middle ground, a reference we can all work from'.. these are it. 'It's a harsh line between a studio headphone that's flat & a hi fi headphone that makes everything sound great'., These are it. If you're young & itchy, go buy yourself a pair of the Rode NTH100, if you've been in the industry longer than the young have been alive, & you don't want to risk regret with the MDR-M1ST.. treat yourself to a trusted classic. These are the bright eyed, slightly older but hotter sister of the MDR7506. Only negative, (which isn't really a negative ) is that these are 'on ear' not 'over ear' but don't let that put you off, check out YAXI ear pads.. as pictured, amazing.. even with my massive ears, turned these into the most comfortable over ear headphones I've ever worn, could not be happier.
