The aux of the headphone is very bad and easily breakable after some time it get stuck or lose in your devices I advice not to buy these headphone you an go for more. this need a battery to operate they are not having any bluetooth facility even they are cheaper but for setting them wirelessly you need to put lots of wire in the rador even some time it get shuffled and allwire are fully messed up and the main problem the strength of the rador is very week and need to update batteries at some specific amount of time. I advice not to buy these head phones
