In terms of sound quality, I would not go into details, but it should be said that the headphones sound properly in relation to its very competitive price of about 20 euros. The fit may be a little unusual, but the comfort is quite OK Compared to the Apple headphones that were standard on iPods and iPhones still a few years ago, these are sound better. The screen is mediocre. Those who place a high value on a good shield should start looking for proper In Ears, these are much better in this regard.
Since I've read that many reviewers have received counterfeit product, hereinafter a few quick tips to distinguish fakes from originals can.
1. On the storage cover the Apple logo should be printed.
2. At the cable of the headphones should "created thinking by Apple in California ..." are.
3. The rubber coating on the handle should be made of high quality and rest.
4. The headset itself should consist of only two parts (see the number of fine lines).
I have the headphones ordered directly from Amazon and this would also recommend that all other. Original headphones are dearer to me than saving a few euros extra. On my packaging is samrick ...., perhaps to distinguish another sign counterfeit originals.
I am happy with the headset and the quality and would order them again. The only criticisms are the not so ideal comfort and the lack of attenuation of ambient noise, so solid 4 stars.
