I like that the headset comes ready to use and with an extra battery. It folds inward and flat to store in a small space. I also like that the volume is not so limited that you can't hear music in a loud car. My daughter had toddler earphones that were sound limiting to the point where she couldn't hear them in the car when others were talking. These headphones do not have that issue. The cat ear lights have 2 functions: constant light and blinking light. The button to turn them off can be felt while the headphones are on.
