Summary: One of two speakers bad out of the box. A different set we ordered had the volume cut out intermittently. Seemed to be related to the volume control. If it worked, it would have been nice. I liked the size and the audio quality when working. Would not recommend this due to the poor quality.
Summary: They work good as long as there is sound playing out a loud enough volume. At low volumes, or if there is no sound to be played, there is a constant (but quiet) buzz sound coming from them. Also, there is a loud (almost full volume) static noise/pop when shutting the system down. I had to use a seperate device to be able to toggle between headphones and speakers to prevent this pop. My guess is that they are not grounded very well internally.
