I'm the first person to review these headphones on Drop. I have been looking at getting a pair of these MSRP $450 headphones for a couple years, after being impressed with the Audio-Technica ATH-MSR7. They upgraded the MSR7 with the MSR7SE and MSR7b, which were very similar but with diamond like coating on the diaphragms, similar to the "big brother" of the MSR7, the ATH-SR9. I was expecting a lot out of these, and I got a lot, but not what I expected. I expected more precise, more accurate treble. Instead, I got some less piercing treble, dampened that sounded clear and audible, but farther away, less fatiguing, and I also got lots of bass. Instead of trying to dominate another headphone by blowing away the competition in one particular area, such as treble, bass, mids, accuracy, mellow response, etc. these headphones deliver a very satisfying experience without trying to impress. They're accurate, sound isolating (a bit), have great frequency across the board, are fairly mellow, and light weight, comfortable, have great earpads similar to the MSR7 and the ATH-WS1100iS, and can be worn for hours without pain or discomfort. They require low power, and are great as a portable (although expensive) option. They are a great set of cans as the go to headphone for most of your needs. Excellent for this reason. Five Stars.
