I was pleasantly surprised by these wireless Bluetooth headphones. Firstly, we must say that we have the choice of three intra-auculaires tips, and once chosen the right tip, they hold well in the ear, even when doing sports (jogging, for example) . Moreover, it is very easy to use and connect to our system, and the sound is pretty good, it lacks can be a bit low but otherwise it is very nice to use this product! Nothing special to complain except this little item!
