The comfort of the MDR-1R is super, the visual appearance is noble, the shield to the outside is very good and the sound even more. In short, the entire part makes a noble impression. Clipping I could not find (I was not yet at the maximum adjustable volume of my system). So much before it and of me a clear recommendation as a whole. The i-anything-functionality I can not test / evaluate the absence of an i-device.
I find that sound perception may always be difficult to describe, but if I have to do it here / want, then I would call it a "transparent" and very well balanced, do you mean, you can see the individual voices / instruments even more complex songs very well differ. All pitches come over clean. For me personally the sound seems very balanced / homogeneous, without exaggerated emphasis on a certain pitch. Some readers may perhaps a certain amount of bass is missing, because here offer other headphones actually more. Whether that is but the point of it, or a musician, is another question. The channel separation is excellent for my taste. Overall my sound of the MDR-1R like it very much.
The sound of the headphones is for me as I would like to have him as a musician. Here's some examples of course subjective selected song who I particularly liked about the MDR-1R, each with inaccurate descriptions of my impressions (all descriptions such as "transparent", "accurate", "punchy" and so on are therefore only as subjective to understand perceptions). For me, a (possible) reference for comparison with existing headphones:
+ Alex Clare, "Too Close": powerful bass, clear separation of individual instruments, voice precision in the foreground (booze in the chorus a little bass from)
+ Jordan Rudess, "Tarkus": so (in a good way) I have never heard (especially from approximately 4:45), super channel separation, clear punchy treble and bass, crisp drums
+ Tindersticks, "Show Me Everything": powerful bass, homogeneous sound, remote singing (ah, how can you just describe)
+ Chicago, "Questions 67 and 68" (live): clear separation of all instruments and voices, and these are in Chicago a lot, and this with a recording from 1971
+ New Order, "Someone Like You": channel separation, accurate instrument / voice allocation
+ Indochine, "Just toit et moi": powerful bass, clear / precise heights, channel separation
+ Dead Can Dance, "The Ubiquitous Mr. Lovegrove" clear stereo separation, precise highs, powerful bass
+ Van der Graaf Generator, "Meurglys III", even the band noise of the otherwise very good digitized Masters is heard, clear channel separation, precise bass / treble, the overall sound
+ Bowes & Morley, "Why did you do it": powerful bass, crisp drums, transparent highs, clear channel separation, overall sound
+ Warhorses, "at home": clear / transparent separation of the individual voices / instruments, powerful bass, impressive "sound carpet"
+ K Maro, "Femme Like You": stereo separation, overall sound
+ Rick Wakeman, "Merlin the Magician": from 06:59 runs here a synthesizer to the highest highs (at 07:18) to the deepest depths (07:40) the normal keyboard pitch range for top form.
+, Etc., etc.
Anyway, I can only say that me the sound of the MDR-1R has absolutely convinced.
However, I also have a few critical remarks: negative in my view are the very short cable and a missing adapter for standard headphone jack (6.35mm) commercial stereos. The should be at the price actually in it, as well as longer cables. The i-Cable I do not need, because I do not have i-something; presumably, it is long enough for the intended purpose. The cable for connection to a PC or a stereo system, however, is definitely too short. The 1.2m is insufficient even in close proximity to the PC. Is so great that one because something has built as an anti-Verknotungstechnik, but what good is that if the cable is too short even for knotting?
Conclusion:
Top-looking headphones with fantastic sound but underground cables recently and with no adapters to standard stereo systems. Nevertheless, I give 5 points because the sound experience is for me in the foreground.
