A good in-ear monitoring system should have enough power and a great and settable built in limiter...
The bad news is that there's no cheap good in-ear system. Any cheap solution is just a waste of money.
Just look around on "Mercatino Musicale" and you'll see how many "used like new" DB and Proel you can find there on sale...
I have been talking about in-ear for long in a big music store in Milan (L.M.) where I asked "real" suggestions. That's what they told me:
- DB or Proel are just "toys", forget 'em! They may even be dangerous for your ears sometimes...
- Shure PSM200 and the mid-price AKG (around € 5/600...) are not bad, but for the price they should be much better.
- the only good system is Sennheiser EW300, but it's not cheap at all, over € 900!
They refused selling me a Shure PSM200 system, saying: "I won't allow you to waste € 600 now... if you can't afford spending more right now come back in a while or give it up and go on with speaker monitors!"
About head sets, they find silly spending only € 200 for the receiver and € 200 or more for a very good set of in-ear-phones. A good standard pair, the one provided with good receivers, are often enough and you can choose to replace them with better ones later, shouldn't you be satisfied...
Still waiting to get a Sennheiser... LOL
If your average stage is not big and you don't run back and forth, you may evaluate using a headphones amp (with up to 8 outs...) and a wired set of earphones, I'm doing that sometimes and it isn't bad at all.
You can even tape the earphones wire together with your instrument cable.
All in all, if you play an electric instrument you have a "leash" already, having two is not that different
