By nyan-san
This is the most successful, standard professional studio headphones in Japan for nearly 25 years.Soon after Sony introduced MDR-CD900 in 1986, CBS Sony Shinano-Machi Studio (now Sony Music Studio) approached to the mother company and convinced them to make studio model. Engineers from both companies worked side by side, redesigned many things including voice coil and its housing structure, and completed MDR-CD900ST in 1988. Model number 'ST' comes from "Studio" to honor the studio engineers contributions.Since it's for professionals, you don't directly buy it from a retail store. Studio orders it from a certified supplier, and studio technicians fix it or replace parts when it breaks. You can still buy it individually from a supplier, but it comes in a small white box with no warranty, no manual, just headphones wrapped in a plastic bag.I should mention the relationship with CD900, V6, and 5706. Those are all very similar headphones. In fact, most parts are interchangeable. According to some Japanese source, MDR-5706 is affordable version of CD900ST for oversea market, introduced in 1999. V6 is unclear to us since it's never been sold in Japan. All shares very similar sound characteristics, clear and crisp, high resolution, wide range flat response. But details are different.First, I'll explain physical difference between CD900ST and CD900/V6/5706. The most obvious difference is, CD900ST stereo plug is standard 1/4' plug with a spring coil, and NOT 1/8' mini-plug convertible. You must use bulky standard to mini plug converter if you want to connect it to an iPod. Next, you can't fold it like CD900/V6/7506. Headband is not complete round shape so that it would tightly fit with years. Last, it's a long, straight, thick cable. In short, it's never meant portable use.It is light weight and comfortable for long hour listening, but everyone has different opinion. Some people said it's too tight fit for their heads, especially when they were wearing glasses.About sound quality. You'll soon notice how much sound you were missing in your source. It doesn't add, emphasize, nor subtract anything, but reveals everything in your source. Even compared with 7506, You can hear every sounds from low to high with balanced, very high resolution. Sound would be fixed in your inner head, but you can pin point your sound position, so you can focus on the sound you want to work with.I happened to find it is quite good for music listing too, however, many people might not like it. Some said it's very flat and boring. Some said it's lacking bass and/or treble is too emphasized, sometime metallic. I understand those complain.Headphones itself doesn't change sound much, it directly reflects source quality. People spend hundreds of dollars on Sennheiser, AKG or Shure might consider headphones as a musical instrument. They might find it's lacking flavor or character. Or, many younger people listening music from computer or iPod might expect headphones to improve their listening experience. Unfortunately, they would never get what they want. It just bluntly reveals how poor their music source is.So you need to understand what you will get: "STUDIO MONITOR". And this one is a real professional studio monitor.

By J. Parmelee
These headphones look almost exactly the same as the Sony MDR V6 but sound at least twice as good. It's too bad so few people know about this headphone because it is the best pair of headphones I've ever owned. People must be scared of the price but they are definitely worth it. These run about the same price as the other expensive brands like Bose and Beats but are much better. You'll want to sell your MDR 7506s and V6s when you get used to listening to these babies. Smooth, detailed bass and crisp,clean,crystal clear treble and vocals. If you like the 7506s and V6s you'll absolutely love these.

By D. L Miller
I picked these phones out after listening to probably 50 different sets of cans in Yodabashi Camera and Ishibashi Music in Tokyo.I did some serious comparisons using music produced by myself and commercially mastered music of several different styles.I weighted phones for comfort, perceived frequency response, build quality etc, and my upper price limit was 1K USD equivalent.These phones just work for me.They don't seem to color the sound in any negative way, and the frequency response fits my somewhat flattened Fletcher-Munson hearing curve.They are comfortable enough to wear for hours at a time and have survived a couple of bouts of total clumsiness that sent them bouncing off a tile floor.I listened to Sennheisers, multiple other Sonys, Panasonics, KLH,Bose, "Beats" (don't get me started) etc. etc. and kept coming back to these phones.They are considerably more expensive on Amazon than in Tokyo, but I wouldn't hesitate to recommend them to anyone that needs a set of headphones for critical listening that can be used for long recording sessions without giving you headaches.I track, mix, and "master" (HA!) with these phones and the end result is somewhat less than total garbage, so that's a plus.
