First, it should be noted that the Bose actually has a lot of good features. Fit and comfort are second to none - phased forget that you even what in the ear. That's very comfortable. The small clamp on the cable carrying sure about this feeling, but primarily responsible for the wearing comfort are probably those little silicone holder in the ear - created with minimal effort and the stuff holds bombproof. Because the engineers and designers have simply done a super job.
What is however of the audio department at Bose in the case, unfortunately can not be said: It is true (as many write here), the sound is very spatially, open and airy. Of these I would like to give back but what if I could have a little more bass. The likely namely come over for my taste much "richer". Well, the bass level is perhaps a matter of taste. But what did not work: the frequency image is a massive over-emphasis of a certain center frequency available (so I take it anyway true) would have to be somewhere at 4-6 kHz, resulting in an extreme "Quäääk" sound, I my with the EQ MP3 player not wegbekomme. To my ears, it can not be - I have used several other InEars for comparison, none had this problem.
Sure, you "it sounds kind of nice" (Restitution is not so), but the yellow of the egg is not the sound (especially for this price). Too bad, just in terms of competence, on which I had set at Bose most (good, balanced sound - does not have to be as high-end closed by big headphones), I was disappointed the most.
Thus, only three points.
