Nice review Peter, was a pleasure to read and learn something about this iem

Great review Peter. I travel in cab a lot and I am little concerned about the noise isolation. Will it block most of the sound? Please reply
 
Noise: I travel in busy traffic

Thanks guys!
 
@JC11 The isolation for me is above average with them. I've noticed that others don't think the same so fit is most likely the key factor for the isolation. I've got narrow ear canals so maybe that helps with the isolation for me. 

Awesome review man I'm one of those that felt isolation was below average (about on par with Titan 1 now that I think about it). Fit seemed fine, and isolation was about the same regardless of tip used (tried UE600, JVC FXT90 stock, and of course RHA's stock tips). It probably just comes down to ear anatomy.
