when I get these first , they be excellent ! Philips have not let I down before . the sound be rich with great bass , but I will say that they hurt my ear for about a week . after that I get use to the feel of they . as for durability , they last about a year , now there be only one phone working . of course , if I fiddle with the wire I can get both work , but I can not bring they anywhere anymore . I really do like these though , so its a pity .
