How wonderful !!! The MP4 is very nice, btw it resembles the iPod at the same design so that recess is not in one. The sound quality is a simply unbeatable price, I certainly do not have an ear more seasoned but my scale player is top !! Any time a little patience if you charge the Sansa music you will have to wait probably around 2-3 sec for the next nothing too serious but nevertheless know. I highly recommend this product.
