Show your devotion to Apple with the Apple Lover Sound Activated Equalizer T-Shirt. The colors in the apple light up in response to the beat of music. It’s great for parties or going out to the club, if that’s your thing. I’ve walked down many a street with a boom box while sporting this shirt, and the tech-savvy ladies just can’t get enough. The Apple Lover Sound-Activated Equalizer T-Shirt requires four “AAA” batteries (not included).
