As a pro sound engineer for a number of years, Im kind of amazed at what value is in a cheap, no-name package like this. It’s easy to install and works well keep my towel warm I usually wear 11 1/2 amazon recommended 11 1/2 I ordered 11 1/2 and they fit great. Another said it was no problem. So convenient to have it fold up on wall and unfold for use without having to open up a floor based structure. The sound is good, Im sure they would sound even better if the buds fit more secure in my ear. Stylish too The worst! It is my best investment along with the kayak. We sized up knowing we needed to, but the width was tight.
