that's the one thing that I thought was lacking from the kc06, the texture of the bass. There is alot of bass there but the way it sounds at times, it's as if the iem isn't sure how it wants to reproduce the bass and ends up making a random sound instead lol
Still unsure how people said they lacked bass, it's got more than enough for anyone not a basshead and for the most part it's really good it's only the sub bass that I find lacking.
The KC06A fixes the texture, and provides quite a bit more bass.
The first batch of KC06 which I ordered from had a lot that were defective (mine was). On the defective ones, bass was almost completely missing. The newest batch of KC06 I ordered from sounds COMPLETELY different.
I still like the KC06A better however, so I'm going to put the KC06 Gold up for sale soon.
