Guys, I'm thrilled. Finally someone thinks a product to the end. This begins with the packaging. Beautifully packed, but consisting almost exclusively of paper and paperboard. No unnecessary plastic, everything is easy to open without scissors or spasm. If I then on the Blisterkacke other manufacturers denke.die should take an example here times. Ok, so let's unpack the beautiful thing and we get the headset, a stylish bag and instructions. This explains a picture and text paragraphs 3 functions, the pairing etc. My tester was an iPhone 5. And the pairing reaches immediately and without any problems. But before the first use I have the headset Once charged via USB (charging status is displayed visually on the headphones) In the meantime, I look at the bag in which can be the flexible headset stowed easily. The material is neoprene moderately. And now the kicker: Everts you around the bag, you get a great arm-pocket for phone or iPod etc in addition even a pocket for a key or money. The bag can be fastened by means of a band on his arm. Good thought along. Meanwhile, I can hardly stand up to the first test, so fix the running shoes. The headset is charged and will now be fixed behind the ears. I already had a previous model with relatively solid neck-strap back. That was of no use, at least if you have worn a jacket and has turned upside down, the bracket has hooked and the buttons have been usurped from the ear. But here sits and fits all. The buttons in the ear and also the flexible Nackenbügel.alles wonderful. The strap on the ear at first press either, after a few minutes I forgot that I wear headphones. Even while running nothing wobbles, I'm thrilled. One but you have to note that the buttons do not go as deep into the ear as in-ear and that brings with it, for example, that the music or podcasts are not heard quite as loud or the environment will notice a little more. But we hear even more ambient noise, which can be depending on the situation of advantage or disadvantage. While running in the park which is definitely an advantage, so I hear at road crossings the car, or zoom storm dogs from behind After 1 hour, the headset will start the ears a bit of press. But one must note the use for this product. Man has left him not to long-haul flights to (would be too uncomfortable in the long run), and not for hi-pleasures (too little bass or too quiet and disturbing environmental noise). It is a sports headphones and for that he is exactly as I want it to me. Absolute recommendation from me!
