Before buying these ear buds I read multiple reviews. As it turns out, the problem wasnt my car stereo at all, it was the AUX cord. Instructions is awful 5 estrellas, pero considerando el precio de estos audífonos, mejor le doy 4. This item does not fit well, considering the brand. im still haunted from this fit. Honest! They are useless. It was thick and while it wasnt an OEM cable as pictured, it seemed quality. I am very impressed with the quality.
