Unpacking:
The package came as always very fast through Amazon. Relatively simple packaging. Nothing special, what you really like to have in the price but is not relevant for the product itself.
Fitting:
At first I was very skeptical with these white "wings" if this works at all with me, as I previously had not been something like this and I generally difficulties with in-ears have, since this can easily slide from the ear at very many models. So terrible Bose! Clear advantage! Sits and fits!
NC:
The noise reduction is simply a dream. I drive every day with the bus to work and use the headphones by quite often. Previously you had to always turn up loud, so that no one will notice the gossip of neighbors, which is located by the road noise, of course, significantly higher than low volume music.
However, as no longer the Bose! :)
Once turned on the NC and all the noises are gone. Votes are still quite easy to perceive, I do not see, however, a disadvantage. Only Ster minor complaint - NC has been activated, you can hear a slight noise, but this is not to perceive when the music is playing. Thus, nothing disturbing.
Sound:
Sonically the Bose are really top! The heights come across clearly and the bass really plays very precise and down to the lower frequencies. More there is not really to say except that with deactivated NC sound EXTREMELY suffers. However, it would make little sense to buy these headphones with NC this then not use it. And should the Battery times be empty, the sound is still sufficient and better than no longer playing.
Other:
Unfortunately, the Bose are when playing on my Smartphone (Samsung Galaxy S5) in the maximum volume not particularly. Normal not necessary, since no Ausengeräusche exist. So it's definitely aussreichen. I, however, love to hear loud, I have managed to remedy with a preamplifier and thus also solved this problem. However, for people who also love to hear loud and this exercise is a pre quite impractical as you re carrying around a device longer with them.
Price-Performance:
The Bose are aufjedenfall worth the money. However, almost 300 for headphones not just a little. Then you could for charging cable already expect a plug adapter and not only the USB cable.

I give "only" 4 star, but because it 2 - 3 smaller weaknesses are, but they do not really carry weight (noise in NC, weak sound without NC, etc). So just buy it !!!!
