The original screws in the headsets are a star style. Love love this feature. if you are looking for a more secure alternative to a flip flop, try these puppiez out-they leave a Really cute tanline on your feet ;~) I even read the reviews and got the really good kind. Wish I could give this amazing piece of technology even more stars. (Edifier H210 without mic) That problem is not here with this one. Never owned a pair of open back headphones before and it was definitely worth the switch. However, once I put them on my reservations disappeared. Hopefully the spigen one is better.
