Managed to pick up a pair for a pretty good price in Australia just yesterday.
My second IEM's after some Etymotics and I am finding the comfort and fitting astoundingly pleasant and easy in comparison. Only tried the tips that were already on them so far.
Sound is quite good straight out of ipod but a bit nicer out of CLAS and amp.
I have an ALO RX-Mk2 and Mk3b+ but these things actually sound nicest out of my old Cmoy. Smooth and fun. Although adding some bass with the bass knob on the Mk3b+ is also nice.
Enjoying so far!
