One of the best products I have ever held in my hands. Quality construction, good battery life, fits well and you don't even realize you're wearing them. It is sweat-resistant, suitable for use in the gym, beautiful, with excellent battery life and sound, simply top-notch for this type of headphones. The software is very simple and user-friendly, it also has a sound equalizer for extra bass, treble, or whatever else anyone may want. Good noise isolation and crystal-clear sound during calls. In my opinion, a perfect product that is worth every penny, even the last euro
