Special Mention at the end of battery beep (every 30sec) making outright unusable headphones when the battery starts to get low (it's stupid because it artificially reduces the autonomy ...) and we can not cut or adjust the beep volume. There is no battery indicator, so it is impossible to know whether you will take the day with or 10 min. Information for this headset uses a proprietary battery, not standard batteries which would have been much more convenient.
And it is not finished! The jack on the headset is a mini, again why not put a standard outlet? You can not charge the headset and use it at the same time (no sound), it starts to make a lot ......
oh and I forgot to turn on / turn off the headset must be pressed for 4 seconds of a button to ca casually like that every day but this is not practical, why not simply make a on / off button it was too much to ask ???? In addition we do not know whether it is on or turn off (no status LED), so you have to press 4 sec and see his condition, we find ourselves in situations where it was extinguished and the lights to see that it was put out, so we put it off again ...... in short, it is painful and it is especially anything level ergonomics.
I think this is the kind of material that is not used not its designer, it is not possible otherwise. I do not even want to keep it too fault for helmet sold at this price.
