The Logitech UE Mobile Boombox is essentially a rounded rectangle with a rubber outer surface. The top has just three buttons, two for adjusting volume and one button for pairing. The backside has a physical switch for turning the boombox on and off along with a micro USB port to charge the battery that lasts 10 hours. There’s also a 3.5-mm audio-out port. The front is a singular grill, behind which lie the dual one-inch speakers that produce the audio. Just behind the Bluetooth pairing button lies a tiny hole which, is the microphone.
