An excellent helmet very good finishes. The box is simple with the accessories that go with (jack adapter, USB cable / micro-usb cable jack and storage pocket). It will be appreciated touch controls, the android / ios app to set the type and various functions such as noise. A helmet of very good quality so that is not the best in its class but perfect for most ears. Being a big fan of FLAC, the sound quality is however not at all go in "off" with the jack cable. I advise you strongly to think about that possibility once the discharged battery. Rather buy an extra battery if you do not keep the day with. This mode is useful according to me for listening to mp3 with low bitrate or phone conversation.
