They dont sound nearly as good as the $100+ aftershokz, but cost a lot less and build quality is good. They look cool, I like the black, music audio is very good but. They didnt look like he was in his bedroom slippers, which made him feel not conspicuous. I have an office job, so I am not on my feet too often. It was a little smaller than I expected, but I didnt look at size as much as the look of it. Good price, very comfortable and it come with a extra battery :-) I am so happy that I’ve pick this one😊 This phone has next gen capabilities with first gen technical problems, all for a price double to triple that of a superior last gen model. My 8 year old son is just now getting into a size 2, so thats what I ordered and I will agree with other reviewers that these run big. Totally worth of money Read the reviews before you buy and make sure you order a size larger than you normally wear.
