I'm looking for an open sounding in ear that is very musical for jazz and classical. Of these two anyone have recommendations. I have the Sony IER-Z1R and Noble Sage and don't like either one. I also have the best in ear Grado's which are not bad. Thanks for your help.

I heard the HM-602 at Jude's local headphone meet yesterday. I liked it very much. I would like to know if it is better than the 601 or 601 slim?

I just returned from RMAF and bought the SR-71B, Cypher Labs Solo, Balanced cable from Moon Audio for my Westone ES5 and ALO Silver Male to Male connector for the Solo and SR-71B. The sound is on the thin side using my I phone with loss less files. Do all these items need break in and how long...
