Apart from the very poor quality of the product: No bass too short cord, do not take up (all this makes you doubt that this is a product of the brand ...), the seller rather "special". You order the black helmet, as specified in the description and he will give you a bright blue model !!! You contact them and if you have the misfortune to ask, depending on your right to be paid back, then ... not even bother to think about it! You are asked to return, at your expense, despite a glaring error, attach copy of the invoice and a detailed note explaining the reason for return !!! All in English, these people not even having the courtesy to make the effort to answer in French. After several email exchanges, I throw in the towel, shame on 'em (shame on them) Stay away from this Con !!
