I joined a new 'second' band last month, and at a practice with them they have an XR18 and each have a P16-M, and it is genuinely amazing - I have been playing with a mono IEM for many years now, but after that one practice, I don't want to do that any more!
Luckily for me, I don't have to as the singer and guitarist don't have IEMs, they don't like them, so it is me and the drummer, so no problem getting stereo apart from the wireless.
I use an XVIve iem, which I am happy with, but la while back I bought a really cheap lekato MS-1 that was just over £30. I assumed it would be poor, and because I got something else at the same time, I never got round to trying it. I tried it last night, and it really worked well.
So I have a gig on Sunday and I am going to use it there.
