This item is a white mini folding speakers. They unfold into two speakers measuring 7 1/2" across and 2 1/2" high. Folded up they measure 4" x 2 1/2". There are on/off and volume buttons. These speakers are powered with a 6V power cord and/or 4 "AAA" batteries which are not included. These speakers can also be used on a cd player also.
I tested it on my cd player and it works great. Please ask any questions before purchasing.
