So everybody in my band needed IEM, but everybody couldn't afford or just didn't need wireless and we went with this. So I have 3 other people saying this is pretty good.
I leave it on the floor and the weave the headphone cable around my guitar cable. It's pretty ghetto, but when playing it's just a thicker cable, so it's no big deal. The keyboardist does the same but just around his keyboard stand. We both power our units with pedal power supplies (9V), since we use fx pedals and at least one slot free on the power supply.
The rest of the band keeps the unit on their belt/pants. They use chargeable 9V batteries. The unit itself is quite light weight, which is good when you've got two XLR cables connected to this thing.
It is plastic, but it does not feel cheap.
As cool as the matte surface is, it gets sticky pretty quick as it gets dirty. I don't know if you can clean it.
I especially love the amount of features on this. The mono/stereo allows me to separate the monitor mix and the metronome mix for each ear and when using no metronome, just click the button and both ears get monitors.
Aux input has helped with last minute "I need to hear that" situations, also just really nice to be able to use 3.5mm.
A limiter in an IEM rig is the law, and this one appears to function normally, though be aware the volume knob seems to be threshold, so boosting a quiet signal a lot from the unit, means the limiter wont save you as much, instead boost the signal before it gets to the unit.
Also be careful when turning the unit on, as the pop sound can be loud, so I always turn it on first and then put on my headphones.
The metal clip on my unit that would allow me to put it on my pants/belt (which is what I don't do) is a little twisted out of the box, so it doesn't stay in the unit that well. Though I could fix that with just a pair of pliers, but I don't care.
The balance knob allows you to adjust levels from the different sources, so that is pretty useful.
In conclusion: I love it. I want a wireless version, because I'm a guitarist, but so far I've found none that match the great features with the amazing price.
