Sound
The reception is clear and is not over powered by the stage sound. As should be expected, the frequency response of the earbuds is not of the highest fidelity, but certainly very suitable.
Features
It had the features we needed. The ability for the user to set level is nice but probably expected. Comes with all you need to get started and extra receivers with earbuds go for about the same price as high-end earbuds alone.
Quality
Light plastic, but hey.
