I bought a pair of these from Penon Audio and I really like them. They are very comfortable and have a really fun sound to them. Bass is deep and impactful and the treble is very articulate and airy. These have a definite V shaped sound profile but are very articulate and fun to listen to. I have not noticed any sibilance or harshness because of the extended treble. They won't be accused of being neutral but they really are great for those like me who prefer a mild V shaped sound with a lot of detail and air.
