I was extremely disappointed with this headset. Not because he is so terribly bad, no! Bose makes here very much correct. Yes, it is made of plastic, but it is very high quality and is quite easy - a must for a mobile headset. The pads are Ohrschmeichler, the ears will fit very pure. Very convenient. The cable may be slightly thicker. And the packaging .... well ..... really an impertinence. For sound: the Bose dissolves fine, but the first thing I lack any bass. In particular rock is not fun and sounds very thin. It occurs to me that the Bose quality of the starting material reflects very well. A lousy mp3 sounds lousy. Flac on the other hand sounds like Flac (or even Apple Lossless). Still sounds rather not bad and it is hoped it will be better if you turn the part a little louder ....... but since nothing goes ...... not at Iphone5, not the Ipad nor the Macbook. In this respect I would the headphones for use on these devices for keeping unsuitable (and no, the Lautstärkebegrenztung was not). Even longer importing the headphones did nothing. A direct comparison with a Koss Porta Pro has clearly lost (while both play never in the same league) and was a big disappointment so far, considering that you look at 5-6 Porta Pros can buy for the money of the Bose AE2i AE2i ( However, holding my first now a very long time). Conclusion: No headset for iPhone (despite "i").
