They are strictly for mobiles which isnt entirely clear on the sales pitch. Not too fond with the price tag on this usb stick as its basically half the price of the actual headset but saved me from buying a new one I guess. Super cute pair. For girlfriend & she loves them! The plastic almost broke trying to get it into shape to fit. I thank you and the Tech that told me about it. On back it has NFC, USB and TF card slot which can play directly from it. Apparently the wick of the straps guided water in because it was a tad absorbant at first. 5 stars for footwear, 5 stars from my dog for tastiness (0 stars from me for the same reason). Which is strange, since it can see it plugged in and recognize the make and model.
