Got the headphone ordered and arrived promptly innerhal b 2 business days TOP! Immediately unpacked and tried super sound! When switch between the radio and the radio was a shaky therefore ma went one or both speakers! I of course immediately contact the seller and the problem described and the had immediately sent new, this is called MAL CUSTOMER !!! All in all very satisfied, more so because some sellers can sometimes take an example for that there are 5 star ***** from me! It's ok to pass what. Function defect. But there is not visible! So ***** S it all Tippi Toppi! Gladly again
