HPA In Ear : Sturdy, simple, good basic features

I bought this to use with Shure SE215-CL in-ear monitors. It revolutionalised playing gigs completely. Being a cello player I need to be able to hear exactly what I'm doing and it prooved very difficult with normal monitors. This devices enables me to control what I hear - and thanks to the 2 inputs, even when there's only one general monitor mix available from the desk, I can take a line from my cello DI's 2nd output into the Millenium HPA's 2nd input and blend the two to however suits me. It takes a while to get used to being stationary, and I would find a wireless setup way more flexible, but this is a decent quality affordable start for in-ear monitoring. It's a sturdy build as well so expect it to last.
