It also seems quite robust, and certainly managed to survive me throwing it off my desk once or twice. The sound quality IMHO is outstanding! UPDATE: Customer service is sending me a new one, very responsive and nice! I needed seed beads a dark chocolate brown. I prefer the Top vs Slim style. 5/2019 update -- the left earbud seems to lose connection a lot lately. It was light and comfortable but the quality is bad my daughter wore the shoes for a week and it fall apart I?d like to see someone undo the bolts in the middle of a parking lot without a ladder or opening the car door. Music feels damper, voices struggle to pick up sometimes, and the effects arent as loud almost like theres something squeezing the sounds ability to travel cleanly. But in terms of quality it?s not terrible.
