Sony SRS-TD60 portable 2.1ch active speaker system (white). It features a 2.1-channel amplifier with a total output of 5W. Power is supplied by the included AC adapter or three AA batteries. The AC adapter is not included. This is a used item. There are scratches and dirt from use, but there are no operational problems. I connected it to my smartphone and listened to music before listing it. Please check the photos and make your judgment on the condition.
