Bose SoundLink Flex II vs Bose SoundLink Micro II

Both are IP67 Bose portables with about 12 hours of battery, so the choice comes down to size and sound. The SoundLink Flex II is the bigger speaker: a single full-range driver in a wide body that plays louder and deeper, with a 5.3 Bluetooth radio and a utility loop for clipping to a pack. The Micro II is the pocket one: 0.73 lb, a 4.1-inch square, Bluetooth 5.4, and no microphone. Owners rate both highly; the Flex II has far more ratings behind its 4.7, while the Micro II's 4.8 comes from a much smaller pool. Buy the Flex II for room-filling sound and the Micro II for something that disappears in a bag.

• Choose the SoundLink Flex II if you want the louder, fuller sound and don't mind a speaker about 8 inches wide.
• Choose the SoundLink Micro II if portability is the priority and you want a speaker that fits in a jacket pocket or clips to a bike.
