Cheap but not tiring and tough

Helmet really cheap but I find heavy (tomb without stopping if I move ...), very tiring if extended listening time and especially fragile. First let go very quickly (only one listener); the second (fast replacement, customer service very good) also recently let go. It's all a bit much for one helmet ....

Small note: I nachèterais more helmet correspondence tried before without having my head !!!! (I know, I know, it's common sense .......)
