Powerplay P1 : Very good starter unit with enough features

Good solid unit with strong belt attachment. It has a built in limiter although i haven't tested this feature (yet) which is a must to try avoid nasty spikes . Better option than the P1M for these features alone. As it has a battery (9V) the gain on the headphone amp is so much better than the P1M which in noisy environments are a struggle to work with. Always carry extra batteries as you will be monitor-less if the battery dies. Some people complain about the weight of it hanging off them but get a long headphone cable extension and leave it on the ground. Obviously this unit is only suitable for people that are not moving around the stage as its the wired version. We have only use them as mono mixes and so far everyone likes the sound off this unit. Has a switch to switch between mono and stereo mixes if you can get an engineer to give you a stereo mix and a handy master volume to control master level of the mix. If this is your first in ears system get yourself a half decent set of headphones or fully commit to the moulds if you can afford. Its worth It. Do not use the headphones that came with ur phone as you will only have one earphone working in this senario from the experience i have had from them.
