the native sound through speakers is very flat and lacking bass. Throuh supplied headphones it is the same. It is not unlistenable but it badly needs the help of a graphic equaliser to bring up the bass and middle. Once that's done it works OK but it is never going to be "hifi" - the hardware chip just isn't great. I do use it as my day to day music player but I do miss the n900 often in this respect.
