This is a cheap in ear so I don't have over expectation on it. Thought not as good as Mark Chalmers said, it is a worthy product.

This system works extremely well as long as certain provisions are made. For example, my unit had an AC adapter that was rated at 220 volts input. In some countries this may work, but wherever normal house voltage is 110 to 120 volts the output of this 12 vdc adapter will only be about 9 vdc or so. The transmitter MUST have 12 vdc or it will perform very badly so you may need to get another adapter at Radio Shack. Make sure the plug will fit the transmitter's receptacle properly and has the correct polarity and current rating. Once you have a comparable power supply you won't believe how well this system performs. I have used it onstage a few times and can go anywhere in the room without a dropout. The sound input is stereo, so when you hook up to a mono output (which is what normally comes out of most sound boards) one earphone will be louder than the other. Not a problem as I only like one earphone in anyway so I can hear the band with the other ear. Also remember to not have too high an input signal as this will cause distortion. If you follow these tips and experiment a bit you will have a good monitor system that didn't send you to the poor house.
