I have this headset for about 15 days and for me it is impeccable, I mainly use it as headphones for movies and music in the house! For sport I'm not sure it's appropriate and'm not sure it would hold up for long joggers for example. It was quick and easy to connect to Bluetooth. Léger for the ears, even though when is not used to it is a little tricky at first. Battery life is good, about 2 hours by full load. Really for the price I do not find any problem. except maybe the small charging connector, which I'm afraid in the end may prove to be more fragile, but for this price it is very honorable!
