They measure 7 inches high, 4 inches wide and 4 inches deep. Both the AC power cord and the audio/power cord to the speaker are about 72 inches long. I will be using these up to the day they sell. The sound quality is very good. I think the volume in the left speaker is noticeable weaker than the right when I put my ear to the speaker for comparison. I have to put my ear next to the left speaker to make sure that sound is coming out of it. The right speaker has plenty of volume. Great for Youtube live music videos. Thank you.
