There's a mobile bluetooth speaker available in every geometric shape, color, texture, and sexual orientation and now Logitech has added major style to its Ultimate Ears line with the Mobile Boombox. The smooth design, 10-hour charge, rubbery coating available in five different colors, and crystal clear conversations via its speakerphone interface combine to make this one of the best travel buddies since Charles Grodin. OK, better than Grodin. He asks too many questions.
