Title: DOES NOT DELIVER!!
Review: Since these are powered speakers I assumed that regardless of the input device, they would deliver an appropriate and adequate sound level. Ahh, not so, Grasshopper. With the matching Coby MP3 player I got them for, it delivers a whisper compared to what they do if I play a more powerful device through them, like with my computer they totally rock! However, they should deliver 75 watts of power, no matter what source the input is, so I am extremely disappointed in this purchase.
