Indeed - the reason I didn't add it to the guide is that I couldn't neatly categorize it. To me it's somewhere between "balanced" and "v-shaped" as they are currently defined by the guide. It's close to balanced, but still not at the level of the VSonic VC02 or an Ety. At the same time, it's doesn't have as much bass as the sets I have categorized under "v-shaped". It's unfortunate but it's bound to happen when you try to pidgeonhole a whole bunch of different earphones into a few sound categories.
Quadbeats 2 coming out next month anyway. According to measurements better subbass and less sibilant as claimed by the manufacturer :)
