Query: Disappointed

I only purchased this product because of the positive reviews I read on Amazon. The first time I tried the speakers with my new MP3 player I was disappointed. I did not expect high fidelity, but I also did not expect obvious distortion when playing classical music at a very moderate volume level. I tried adjusting the volume using both the volume control on the speakers and the volume control on my MP3 player, and either way I heard noticeable high frequency background distortion, sort of a slight buzzing sound. Maybe the unit I got was defective. I don't know, but I sent it back immediately. I would not recommend this product.
