The caps are nicely textured and feel nice to type on. They cancel out the external noise and allow me to concentrate on the podcasts I like listening to. Additionally, I have very flat very wide feet. My kids use both spays and shoes look white and smell pleasant. Seems like a possible fail if the screw accidentally becomes loose. Super easy to use: Simply take them out of the charging box and put them on each time you use them, they will be automatically turned on and connect to the phone (after initial pairing). however they?re a men?s shoe, so a size 10 wouldn?t fit me. First of all I would like to say this product is a charger first and foremost and it does charge devices just fine. Left earbud is single click for volume up and double click for volume down. Size: I like that these shoes last for a long time because of the sizing.
