Have long wondered whether I should take a high-priced product beyond the 100, or to rely on the currently still rather few, but really good reviews for this DeleyCon Nano Sportster. Since I'm going to use these headphones just for sport, it will then become this and I was not disappointed. Surprisingly good feel, ease of use and good sound (much louder and better than similar, wired headphones from the same manufacturer). The fit and the seat in the ears is very good for me, but you have to spend some time to find the optimum settings (size of silicone plugs, "sailing" and angular position thereof). The information of the headphone as "pairing" or "Power On" etc. are good and useful, as well as accessories such as the small bag that I find very useful. Even the headphones, unlike some competitors is really relatively small. That there is a noise when the neckband rubs his beard or on the skin, which is not attributable, in my view the device. The almost all headsets with a whatever kind cable. Do not disturb this sounds particularly. The operation of the buttons on the controller is of course due to the size a bit fiddly, but the functions are all given (Samsung Galaxy S4 and Note 4). For performance of the battery, I can not say much, for that I have too little had the device in use. Let's see how proven the headphones over time.
Update: battery will last at least 5 hours.. Running no problems, however, you hear, depending on the length of your beard and clothing and position the headset more or less in the ears noise. The sound is more great and loud enough. What in the end even went quite well while running, was the key operation. I stand by my recommendation with 5 stars, especially at this price.
