Hi I am sharing my opinion about sony MDR-XB250 headphones. this is a worse product of sony. I brought this MDR - XB250 headphones from amazon few months later its design is fine and looking glassy. when you want to put in your bag it can be in round shape. firstly it works good but after one month left side sound is not heared properly. though its price quite high than others it does not good quality product. it is bad in performance because bass is not good. I am not satisfied with this product.
