Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm. Result is that a large percentage of the diaphragm cannot be directly driven by those conductors. Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, result is significantly lower distortion than conventional dynamic headphones.

Great Headphones at a Great Price!
These headphones are amazing for the value. At this price it's impossible to get a pair of better sounding headphones. The highs, mids, and lows are crystal clear with very low distortion at even the highest volumes when running them off of an amp. The bass, I found to be lacking a bit when you get to the lower frequencies, but even then, they are far superior to any other headphones in this price range. I listen to all types of music from, rap and hip hop, to rock and reggae. These headphones were able to surpass my expectations for every single one of these genres. The comfort level of these headphones is also very good. I am able to listen to these headphones for hours on end with no listening fatigue at all. The only con that I found with these headphones is that they have a rather long break in period. The manufacturer recommends 150 hours of playtime for these headphones to be broken in. While these headphones sound very good without being broken in, the difference in sound quality once they are broken in is night and day which makes me wish the break in time was a little quicker. Other than that, this is a great sounding headphone that is more than worth the price.
