I would say the reason for this is they are using the shoes for high-activity sports that put a lot of stress on the arch. I tried using earbuds but at times they cant hear me to well. A larger cover plate was manufactured for my application. Once paired, it works as intended. I bought two for my closet . These pair very reliably every time I take them out of the case, almost as quick as my Buds do paired with my S10. Looks nice on the table. Just need to find which moving box holds the rest of my spices! a lot. And I was able to fit way more than I thought I could with room to spare.
