Mine worked very well, then I didn't use them for about 1 year and then they stopped working at all, couldn't be charged. I have now asked everywhere and looked on the community and so many have had problems with these headphones. I sent them back (warranty) and got my money back. And will definitely not be buying these again. Kind regards

I also had problems with the first ones, then I had to return them, then it worked, but unfortunately I don't need them very much.
