The regular prices are:
Ety 4Rp - $300
Shure SE420 - $400
UE $700 - $150
I'd go with either the Etys or the Shures. Shures are more comfortable and have more bass. Etys are the most detailed IEMs available. They're even better than most multi-driver customs. You can improve the bass by changing the tips. I use Klipsch tips but the most popular kind are the Shure olives.
Unlike other Shures in its price range, the SE420s don't have detachable...
