Finally demoed the 1+2 with the gold+silver cable.
Hard to fault sound, with a dark signature yet sibilant on some songs. Great soundstage with natural imaging, mids are well detailed and never masked by the ever presence of the bass. Somewhat longer than usual bass decay, IMO.
I must say, my major concern is not the sound but the build and comfort. Isolation is also sub-par, maybe because of the vented design. Visible air bubbles in the shell and less than polished finish, very different the the MH334's craftsmanship. The thick and heavy cable made the non custom fitted ear tips a hassle to get a good seal. Considering a TG334! is cheaper and MH334 is not that far off if available, it just isn't competitive enough with great value IEMs like the ASG2 around.
