it go without say these headphone be a tremendous upgrade from the earbud that come with my ipod , but I be extremely surprise at just how good they be , especially because they be price so reasonably . right out of the box I be surprise by they quality ; I could hear , for example , previously-unheard breath and bowscrape in a few quintent piece I enjoy . moreover , I could really notice that music of all type `` spread '' from ear to ear whenever I use these headphone ... with other phone I have try , include some studio model , even well-produced music tend to stay more-or-less in the middle . I enjoy these phone so much I be tempt to try higher-quality phone from Sennheiser : if they sub - $ 30 phone be this good , they higher-end phone must be unbelievable . further , they be extremely comfortable and come with a generous cord . I can wear they perfectly well underneath my motorcycle half-helmet , and I can hear they perfectly fine over the roar of my motorcycle .
