It was nice being in the presence of a helmet of the Basic range, we say that this helmet is not too poorly designed. From a technical point of view it has what it takes: pairing buttons, telephone stall, volume and concentric micro-USB for charging which also occurs relatively quickly. The handling is good, certainly better than other brand helmets that I have; it all depends of course on the continuous usage time and volume. As for the resistance, it will take time to test, but with some manipulation, it seems to me correct. I was pleasantly surprised to have in the ears messages in English for tensioning and connection, it changes the beeps that are no longer remembers the significance spent 1 month. I have not felt that irritating feeling of foam or even the fact that it is too wide: the port is correct without being thoughtful comforts. There or fishing this helmet is made in the sound: it is no relief even if the volume pushed up does not cause saturation, the whole remains desperately flat, so I removed one star and I could have been but harder for a product "basic" it is in this that we are to expect.
