This holders are made for AirPods Pro, but also work very well with other AirPods generations.
Using two little magnets (4mmx1mm) and a strap for glasses, you have a really cool gadget that you can use, for example when running (if you are afraid of loosing them) or just let them hang on your chest in between calls. The magnets will keep them together.
The design allows you to still using touch control and the buttons.
Hope you like it!
