Product Review

Official speaker for the P-SB7. It weighs only 2 oz and the ball shaped speaker is 2.25 inches in diameter. Plugs right into the side of the P-SB7. Will work for any electronic device that has a port for an external speaker. This speaker has to be charged up through a USB chord. Comes with a USB chord for charging. One must also switch it on. There is an on and off power switch on the side - partially hidden under the black protective foam padding.
