Jingle Balls are Bluetooth enabled holiday ornaments with a really decent sounding Bluetooth speaker. Play music right from the branches of your Christmas tree via your smartphone, iPad, etc. No Bluetooth? I also demo the Kinivo mini speaker that can be used with any device that has a 3.5mm headphone jack.
