It connects to WiFi so that you can access high resolution streaming services. No estan mal, el diseño es bonito y cómodo, pero el material si se ve barato. And it was not my feet and after being used,I cant send it back. I normally love control freak products but this one is a miss, maybe get the soft version but still this won’t make you better. Very happy indeed. Dreadfully overpriced, no value for money and, in my opinion, pretty poorly made. Aslo the fact that its not dirt or water proof makes it purely a home speaker. if only it werent so large and I could have figured out how to work it. The boxes are clear so that makes it easy to see the contents. They hurt my feet, feel so heavy, clunkier and i cant wait to take them off.
