Glasses are authentic but they came dirty and the case was damaged with no cleaning cloth nor cloth case/baggie. They were comfortable but they diminished the bass too much by putting more distance from your ear to the driver. Ordered half a size larger than normal and they fit wonderfully. I will say the leg holes are just a little too right around my thighs, but my thighs are. I have 2 universal chargers, so I can plug the usb cord into the charger (doesnt come with). They are easy to use whilst running - skipping tracks, adjusting volume etc. These are super cute but not well built. I used them outside to hang a wind chime that weighs 3. I have owned Minnetonka shoes in the past, they are hit and miss, sometimes good sometimes not. Zero base and hissing noise while listening.
