Actually I came here to award the SD2 for being probably one of the best all-rounders yet. Although it's a two-way BA design, it is incredible cohesive and musical. Comfort and build is currently without competition, regardless of price.
Sadly it is not the StageDiver 4 trying to push the limits of universal in-ears yet again, but a budget dynamic design called the "InEar One". All I know right now is that it's a v-shaped dynamic with flat cables.
