I have the headphones for a week now in the test. Let's start with the Postiven: 1. The headset is relatively low and has for its price a very good sound. We come to the negatives: 1. The cable is long astray, if you use the headphones in the house, but on the way, a total nuisance. 2. The ears are extremely hot when you longer than 30 minutes, the headset. bears. In addition, they quickly develop a discomfort. 3. At the same time the total KO reason these headphones to buy: if you go by bike and it is just a tad windy, one understands nothing (although it has greatly untwisted) ambient noise isolation so = 0th Anyone who wants to use the headset on the go, you should definitely look elsewhere.
