Build a party at home with the Sony GTK-PG10. Via Bluetooth you stream your favorite music wirelessly to the battery speaker. Fold out the top panel of the outside speaker when you are having a party. This way you have a small table with 4 cup holders. The top panel is water resistant. Because of this you don't have to worry when drinking falls over. Do you feel like singing along with your favorite song? Then connect a microphone and your voice can be heard directly over the speaker.
