I?m super happy with this purchase. I havent tried opening the mouse yet, but its nice to know I can do so easily if I wanted to. Estan super cómodas y el diseño es muy bonito. Super comfortable fit! Sizing is smaller that what should be. It does not have the bass response I expected at all but the overall sound is as described by Bose as "The widest sound of any smart speaker. I really like this set. I needed to disassemble the clamp on one side in order to get it onto the rail. hopefully bose will fix it, then i would say 5 stars Its left ear piece completely stopped working.
