Cheap plastic feel. BUT, You CAN turn this off. I know that the vionic shoes are expensive I just really wish they would make some awesome looking shoes. It?s connectivity also very easy and fast. Had to press it really hard to register. If I had long toes or pudgy feet then the sandals wouldnt fit right. Un excelente producto, reproduce música muy clara y sin distorsión, los probé en dos reproductores de música, el xDuoo x10 con formatos DSD nativos y en el fiio x1 II con formatos WAV, quede muy satisfecho. Now trying to find a comfortable solution to gaming that doesnt suffer feedback has been a trial and a half! After reading some reviews and watching many YouTube reviews (many are just advertising for views), I settled on the LG TONE Free HBS-FN6. But these Birks are perfect.
