A:Answer There are several cosmetic and performance differences between the Megaboom LE and Megaboom 3. Cosmetically, the Megaboom 3 is slightly wider in circumfrence (87 mm vs. 83 mm) and weighs a little more (925g vs. 877g), has it's charging port in the back as opposed to underneath, uses a different mesh pattern which allows the it to be dustproof as well as waterproof. The Megaboom 3 also doesn't have an auxilary in port like the Megaboom LE does. Also, the Megaboom 3 has an extra button on the top that allows you to play/pause/skip through tracks. Perfomance-wise, the Megaboom 3 has a longer bluetooth range (45m vs. 33m), higher durability rating (IP67 vs. IPX7), and works with a Power Up dock. You can pair both to the Hyperboom through the app, as well as pair them together. - Richard from Logitech
