Before I bought the BackBeat, I was 100% wireless, so I had the wireless transmitter on the guitar strap, and I had the IEM on my belt with the earpiece lead going up my back, either under or over my shirt, depending on the circumstances. That way each component was attached to the appropriate object (either the guitar, or me). This got complicated with the addition of the BB to the strap. I want it positioned as close to the center of my back as possible, and the transmitter for the guitar still lives near the bottom of the strap, closest to the guitar jack. For the monitor, though, I still keep the receiver on my belt, I suppose out of habit. I unplug the cable going to the backbeat, and I take the IEMs out of my ears and leave all that draped around the strap when I take off the guitar. I hadn't really considered moving the monitor belt pack to the strap. Partially due to inertia (I've always done it that way), and partly because I don't want the transmitter and receiver to interfere with each other. I don't know that they would do that, but as it is I have to keep my phone away from both of them to prevent unwanted noise in either system. I might consider moving the monitor belt pack to the strap to see how that works.
