I personally haven’t I used this. it fit and it holds a charge! I slid my foot in and was barely able to affix the strap in the last hole. And, if you are not sure that this is you. It can be used through either AUX or Bluetooth. Good quality all around, and they should last for a while. au niveau son, plutôt pas mal, assez confortable dans loreille. He did it quick as an expert. Not only does this chair look better but it feels great. A huge plus is that it cane with multiple fittings for ear hole size.
