hey christcwl9 - happy birthday dude..
anyway.. the quality that produce depend on the music file too.. if the music file is bad then.. how to make clear comparison..
actually.. there are some method to test audio/speaker quality.. but for most of us.. we just need to hear the sound that produce to judge the quality of speaker... thats what i do...
1] comparing two phones - N82 and N85 [regarding speaker quality]
2]use same file - Womanizer [good quality, high bitrate]
3] no extra setting [all setting set to default]
4] N82 and N85 in latest version
5] play.. the music [repeat it by changing volume.. from 10% - 100%
6] results :
N82 is great in term of loudness and less noise...from volume 10% - 100%..but overall N85 win..
why ?? it is because.. N82 doesnt produce sound as loud as N85[although it is 100%]..so we could here less noise ..
and N85 is really loud[70% is so loud]..N85 good in balancing the music that produce.. it is just better than N82..
overall - N85
but its for me.. different people, different ear ,different result

Thanks kae7, oic...yea i agree with u that diff ppl diff ear and result....now i know dy...thx for telling me...i appreciate it very much!!!
