To be honest @JimBobTTD this was far too much of a thrown together in frustration with the monitor system affair for me to have a valid opinion on the equipment. We run 2 mixes, the drummer has her own mix with wired in ears and has always used that and the other 3 of us share a mix. We all had different ear buds, none of which were expensive.
My observations for what it's worth are really about in ears as opposed to normal monitors rather than the equipment available as that is a never ending affair.
The sound levels we usually get on stage were reduced dramatically making it a much more comfortable place to be albeit with a certain feeling of being detached from the proceedings, this is something I'm sure we'll get used to.
It quickly became apparent to me that we needed pretty much everything in the mix as the back line and drums were cut out to a great extent, as I do the sound I did this but took it easy with the kick and the bass as I had no idea how everyone else's earbuds were coping.
Biggest bonus for me was the vocals, we all sing and if I say so myself we can all hold a note but the ease of pitching with being able to hear yourself and everyone else was great. One thing to note was when the backing vocals came in it did seem to compress/limit with the increase in signal, I assume this is a good thing and a safety measure. There's also no strain singing either as your not trying sing louder just to hear yourself.
I do get the feeling that what's in your ears is going to be far more important that the actual transmitter and receiver you use as these cheap units worked very well with no distortion or drop out and we are pretty active and mobile during our show.
Think the KZ ZS10's are going to be my next purchase. What do you think of yours ?
