These are great. Very simple, yet effective. I hate working in the yard or bending over to clean only to have one fall out. Having to hunt for one can be a real pain. This strap slides on easily and securely. You wont even realize its there. If the airpod falls out, it just hangs there around your neck. There are magnets on the middle part. It helps the airpods not get tangled. There was a magnet that seemed to be in the wrong way since it pushed away. This might be part of the antifatigue therapy. It still works well and a great investment for your airpods!
