Buen producto Lo recomiendo, emparejamiento fue fácil con un dispositivo iOS, simplemente selecciono de la lista de dispositivos y se conectaron. It protects my Case every time. I emailed sales at Wantek and got a response less than 24 hours later. The grommets on the inside of the shoe where the buckle is attached hurts my little toes on both shoes! It was very easy to assemble, it took me about 25 minutes to assemble (no tools required) It was perfect for my shoes and it sits leveled on my carpet in my room. My only complaint would be is that its heavy. Super cute, but the top opens up easily. First really poor review I have ever authored. Bought as a gift for my granddaughter. This is a rare feature to find inbuilt into the earbuds.
