Logitech Mini Boombox (Black) Logitech Mini Boombox (Bluetooth Speaker) Black And White is a very compact--and cute--Bluetooth speaker that has a built-in rechargeable battery, speakerphone capabilities, a line input, and touch controls. Its sound is impressive for its tiny size. Beneath the friendly, rounded frame of the Logitech Mini Boombox lie some seriously mean speakers. This small Bluetooth speaker delivers surprisingly good bass, but not at the expense of higher tones. It also has a built-in mic so you can take calls from anywhere, great for an impromptu conference call.
