thanx for replying, im using windows media player, not sure on the bitrate cuz i cant find a setting for it. my bad should have clarified better, not using headphones like that as i know it takes more to power them, panasonic earbuds is what i have. ive used the audio booster but doesnt do much cuz for the most part the sound is still not clear/disorted, like a wav vs. mp3 sound but thats not the case cuz it do it with wavs too. ive end tried to use my tp2 in a friends car vs there cd player and the same results happen. im very music orientated and would like my music to sound good.
