Query: surprised at how bad they are

I got these for work, because I want to listen to my MP3 player, and sometimes I am in an area with no AC power. Since these can use batteries they appeared to be just what I was looking for. I didn't expect great sound, but I was still surprised by how bad the sound really was. Take a pair of headphones, plug them into your MP3 player or whatever, set them on the table and turn the volume up. That's kind of how these sound.I was in a hurry to get some speakers and didn't do any research on them or what my other options were and I am now regretting it. I consider these to be a waste of $30.
