I pulled the trigger and bought two of the Tangzu Wan'er, one black and one Green... they ship from China direct from Linsoul store on Ebay, and it will take quite a while to get here (the Zero 2's took an entire month to reach my mailbox).
The Zero 2's have a more jagged, zig-zaggy shaped housing, the Tangzu Wan'Er seem to be a bit more round... so maybe they won't hurt my ears as much... also the tuning is supposed to be more "warm" (allegedly).
