Hello everyone I have bought noise shots sport by spending 2500 bucks and now I am using them they are truly wireless free and it is very comfortable for gym for running for listening music and they are not secure fit some times they may fall down and then they are Ipx4 sweat proof and then comes to the charging they are magnetic charging after usage of buds just put the buds into the aluminium charging case automatically they will be charged at first but now I am having problem with charge of one bud it has to be kept always charging it is not charging fully always it should be charged and then it has a mic for calls for one bud and it contains so much disturbance and so much noise and the caller cant listen to your voice clearly
