I tend to disagree with the review somewhat. We all hear differently so don't take it personally.
1. Earphones can be worn over ear. I have been using mine over ear since I received them. Fit is fine with the right eartips, no problems there.
2.
I don't find them dark or bloated. Actually, I find the sound to be rather on the fun side of neutral, with a bit of a darker sound but not overwhelmingly so (try the RHA t10i, if you really want dark and bass bloat),
3. I do agree however in that they don't have the greatest soundstage. Also agree on treble remarks. Mids sounded fine to me and I did not notice any nasal tones to my music (flac or very high mp3's - indie rock, EDM, jazz and classical).
4. As for lack of isolation, this can be a positive thing if you use it outdoors, or in a workplace where someone may need your attention.
5. Price/performance - I would put them in the $100-200 range. Of course there are those outstanding earphones that perform way above their price point, these are not in that club. But if you can get them under a $100 you are getting a nice bargain.
6. I would rate them a 4 out of 5.
My source is the AK120ii.
Cheers.
