They are a little larger and taller than the included feet, and I dont regret spending extra for them. Charged my phone extremely fast too. Used for conference calls and remote learning via Zoom/WebEx, gaming, listening music, etc. *I posted the initial review 5 month ago when I purchased my baby seal. Not only were these heels a perfect fit, they were very comfortable, I wore them as soon as they arrived, and had zero foot pain during and after the long evening party. Definitely not worth 20$. It’s become a staple in our household. Product was used, didnt have shoe laces, was dirty, wrong size and had previously been returned for the same reasons. They dont look as high end as the Bose but then again they cost $100 less so I dont mind. Control are on the right earbud.
