The SHE9800 in-ear-headphone is really the state of the art earphone, I have never imagined before that I will finally find my dreamed of earphone. I use the earphone for my MP3 player (also the best of its kind) and it simply gives me new experience in enjoying music from it. Now I can exercise all the sounds type produced through adjusting the EQ. previously I never bother adjusting the EQ of my player because it simply does not give me distinctingtively different sound, but now, wow I can very clearly perceived the difference of each sound setting. The bass sound produced is simply breath-taking and clean. Trible is likewise, crisp and clean.
Other thing that I like most about the earphone is the design. It simply fits in into my ear canal perfectly. In short, I ocassionally forget that I am enjoying music from an earphone and thought the sound comes from my portable stereo set.
