Dumbest customer service I have experienced so far. The quality of sound it great, and the noise cancelling mic worked well when I used it for skype video calls. When I leave the car, the E8 3. So it?s a lot of shuffling your feet while waking around. This is a great sandals,however I dont know why this kind of designed hurting my feet. PAINFUL. Just received this product today. They feature a enjoyable sound signature with a slightly boosted low end. AVOID Son muy cómodos y amplias, fui asertiva al pedirlas de mi número usual, creo que aunque son bastante amplias si hubiera pedido un número menor me hubiera apretado la tira sobre el empeine pues ahí va más ajustado y posiblemente me hubiera lastimado.
