as always cared delivery and packaging. Amazon thank you! about the product good performance in the ear but do not rely on the package: the bass boost is nonexistent! its low but clear. At this price it should not ask for more. Furthermore cheapest products are as well. After seeing the behavior in time but because of the delicacy of the cable I'm not very optimistic. I do not recommend this product depends on the use, however do not hesitate to compare.
