00BT weren?t/aren?t that impressive so I decided to take a chance on the Beyerdynamic Byron BT. I?m in love with the Ionic crocs comfort. Well they fit perfect. Needless to say I was, and am, very impressed with this company. They look nice in but hurt my ankle (back rubbed) and toes. Very simple and functional. And after that, the tread is gone and the shoe is like a skate on wet surfaces. These didnt fit in our LG G7 ThinQ phones - we are returning so cannot give comment on the fast-charge ability. Thought Id use it to make a few finials for garden obelisks Ive built . Bottom line, you cannot go wrong with this mouse or Logitech.
