Turns out that they have lots of options: Bali Strap, Whisper, Venice H2, Newport H2, Evo One (listed in order of list price). My main issue though is the quite horrible sound quality. On the positive, they do have a two year limited warranty, so that does give me peace of mind. ?????Hope this review helps ya?ll out. No deep bass but again these are designed for kids, I don?t expect it to sound like Jabra, Sony or Bose. I?llntry To return them but I live outside USA so it?s not easy. But it hooks to the case on a silicon tab which will eventually break off. 5 for myself if they are available. My feet got a little sore just because Im not used to wearing heels but the shoes were absolutely perfect! It?s very soft and warm.
