These are EXCELLENT earpiece, the cases in which are stored these headphones, is a quality worthy of greater brand dautant + that this box is DAUTE several different fitting to suit your ear. The telecomande is simple, discreet and very good qualities. The only weak point that I stink and find the sizzle that occur when you move the jack. I highly recommend these headphones. Ps I bought in supermarkets, I can not tell you anything about the livrement and provenance. Ah yes the quality is magical, quality price ratio IMPRESSIVE! Low acute as everything is perfect.
