It has really good build quality. Overall it is warm and smooth sounding. Great for Pop, Rock, and music with vocal as it has a well textured and detailed mid range. Bass will only comes out if you have a really good fit, still it doesn't go very deep. Treble extension is a bit smooth, so there isn't a lot of sparkle at the top. As with most earphone with good mid, soundstage is kind of weak. I don't see it as a good earbud for Classical or instrumental music. I paid about $70 on Amazon Japan and think it is quite a good price for its sound.
