This is a great silicone cover to protect your AirPods and the AirPod case. It works but the sound quality is a little poor. These belts are good. 5 cuz it fit nicer. 5 inch ports. The kids bike was easy to heft up to the bracket. the case still opens with this on it and it doesnt seem to come off easily when i open and close it. Each speaker is adjusted independently. The toe portion is not too narrow; the strap is at a perfect location, and the width was perfect after pulling the adjustable tie. Youll only need to do this once to set things up.
