Wireless Guitar Practicing: My "Home" rig uses the Line 6 G30 and Sony WH-L600. This is the least expensive pro solution out there. G30 is what it is, you can find the reviews on that in other places, perfect for home use.
The Sony WH-L600 are awesome. Turn off the Theatre mode, Digital 2.4GHz Transmission, Less Than 1ms Latency. "Closed Back" headphone design so only you can hear them. No Receiver Pack Required, built into the headphone. Great Dynamic Range with very little compression. Wide Frequency Response for "Play Along" applications. This is a single channel IEM Solution for under $300, that competes with $1K IEM systems. The only down side is that Line 6 Didn't make it.
I've tried so many other headphones out there. All of the Sennheiser RF Solutions (RS175/185) and yes there is an annoying 30ms of Latency, not acceptable for IEM. The low end RF TV monitors all drop out or Compress the Cr@p out of your tone.
