It doesn’t really matter what you’re doing—hiking, biking, cooking dinner or hanging out. You need music. We designed a speaker that keeps pace with all of your adventures and delivers unmatched sound for its size. The SoundLink Micro speaker is small, but powerful. Super rugged and waterproof. It features a tear-resistant silicone strap—so you can take it along wherever you go. Because, when a speaker this small sounds this good, you’ll never want to leave it behind.
