Very good headphones and very good quality. Helmet comes a day before the scheduled date. Connections made with the iPhone 6 more without any soucis.la us restore the sound is excellent. The helmet dives we live in an atmosphere that is appreciated and it is happiness. But for that I have received today I have not yet explored all of its functions. However only negative point record is either in English or Chinese is difficult to translate so. Very satisfied with my purchase for the price complaints. I recommend it. Thank you
