Although a tad more spendy they have come down in price. YOU should be jumping on these. They are seriously good. Think a Tad brighter Trinity Delta or Dunu DN2000.

They are seriously good. I spent 8 Hours with them last night @ 100 Hours of burn in time. Extremely Detailed, Tight natural Bass. I was worried they were a Tad on the Brighter side for my tastes but a pair of Comply 500's tamed the EQ.
Don't worry, they exhibit ZERO signs of Siblance. I threw a Recording at them that almost exhibits ssssssss in the actual recording and it didn't make it come out. (SOAK doing Zeppelin's Immigrant Song)
Simply superb for the money. I can't wait until they are fully Burnt in.
TWIN
So TWIN, if you had to choose between the Bettes and the Rock Zircons which would you pick? I assume the higher priced IEM would win out?
