One need only ponder the phrase "headset for active pastime, the mind immediately goes for the mind. Well, no, I can still somehow understand people who are in the fitness club are not part with wearing ear gadgets - a business there, all the cases. But these people I meet are not very many, so players are listening. A phone or lie somewhere nearby, or are buried in the locker room turned off. If we talk about hiking, then the last thing I would take with them - it is just the headset is. And in the mountains, I would not buy it. And here it is possible to speculate about secure phones - the audience, which needs these things are very small. Honestly, I've only seen one such person is fairly well-known sports photographer, his life is dangerous, difficult, and the same applies to the wearable technology. I can understand why he has a collection of protected Siemens in various states of corruption, although in recent years, it is firmly hooked on the Nokia 5500, I think it is now wise up about buying SE C702. In general, what I'm saying? By what right did just sports headset will not attract a large audience, an attempt to ride a dead horse. In addition, if we talk about our country, there still could be involved the audience's attention with all sorts of sports activities (there is a project with Samsung and Adidas, will be protected and vehicles), coupled with the phones, but in my opinion a peasant, Samsung WEP430 has turned out pretty strange.
