Excellent little gadget here, perfectly usable as a rather decent set of sunglasses but with a party trick- they have an earpod discretely mounted in each arm and a mic too so you can actually make and take calls too. 3 little arm mounted buttons make it easy to operate too. *please note they have changed the design slightly from the picture towards a slightly more rounded frame to be a little bit more unisex apparently!
