Sennheiser in-ear, for example, the only true complement to my NWZ-X1060B - overall dynamics, homogeneity, transparency and especially the excellent space can now, in the mobile space, really nothing to be desired. The crystal clear precision and the intensive, well-defined and perfect bass are reproduced in a warm, especially vivid authenticity and detail, as I have heard so far in any other in-ear and say even, conform consistently with my Vorrezensent Martin Michel, IE 8 is able to deliver the sound of a high-end system.
Despite the many ear adapters Sennheiser generous this in-ear attaches, I could not find suitable for my (probably spoiled) ears. In order to achieve the best possible audio reproduction, the IE 8 must, however, 100% are seated properly. When I think that, in my view, bought overpriced and overvalued MDR-EX700 Sony, I got from my dealer a set Sony EPEX 10. The Sony-IE I have long since sold, the ear adapters have remained with me, fortunately, because these are the icing on the cake for IE 8 and guarantee the best possible fit and fit precision. Should the sloping auditorium with the enclosed Sennheiser ear adapters not come right, I can recommend the EPEX highly enough.
And no, it must not necessarily a Walkman X Series or Cowon S9 be to get into the audiophile (!) Enjoyment of IE 8! With my two "weaker" Walkmen (NWZ-S639 and NWZ-A818 FB B), which blends very well, although the space and the attention to detail are somewhat limited. My iPod Touch could not lure of the "Reserve" and the IE 8 whether and to what extent it comes to other Apple players out of the house in question, I can not judge.
My conclusion: The Sennheiser IE 8 is in terms of workmanship, comfort and last but not least the ultimate audio reproduction in the field of in-ears. The result can be hear and feel, moreover, the price / performance ratio is excellent.
