TINY. UNTIL YOU TURN IT ON. 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. We put more in. You get more out.? Every detail of SoundLink Micro—from the custom-designed transducer to the silicone passive radiators—is meant to reproduce sound that's better than any speaker of its size. You can't make a speaker perform like this one if you don't engineer it that way from the start. All the places you'll go Wherever you're headed, SoundLink Micro is designed to tag along. Strap it to your bike, your backpack, your cooler. The tear-resistant strap is super reliable, so you know it'll hold just as tight whether it's the first time or the thousandth. STANDS UP TO WATER FROM THE INSIDE OUT? ?When it comes to waterproofing, we wanted to make a speaker that not only performs the first time you get it wet—but every time you get it wet. We used an IPX7 rating as a benchmark, then took it further. We rigorously tested our speaker for all kinds of situations. We built this one to survive a fall in the pool. Or in the ocean. There's no need to panic if you drop it. Just pull it out and hit play. Materials matter Accidents happen. But that doesn't mean you should be left with a broken speaker when they do. That's why we chose silicone rubber for SoundLink Micro's exterior. This high quality material allowed us to eliminate as many seams and gaps as possible (and it holds up to dents, scratches and cracks). It's portable performance—for all the places you want to be. Bose Connect app Control your SoundLink Micro speaker's Bluetooth connections easily through the Bose Connect app. Have a friend who fancies himself a DJ? Switch devices through the app and let him take control. There's more. For those times when loud just isn't loud enough, use the app to connect two SoundLink Micro speakers in Party Mode. Or switch to Stereo Mode. Instruments and vocals will naturally separate—making your music feel alive. BATTERY Other speakers may have a battery that plays a little longer, but ours has one that plays a lot more of the bass you want to hear. All while still giving you up to 6 hours of music that's deep, rich and full of life.   SIRI & GOOGLE VOICE COMMANDS Don't have your phone nearby? Don't worry. Just press and hold the multi-function button to access the voice input for your phone's Siri or your Google Assistant right from the speaker. SPEAKERPHONE You've seen it before. Everyone crowded around with one friend on speakerphone. You struggle to hear them. They struggle to hear you. Not anymore. SoundLink Micro lets you take calls right through the speaker, so words are more clear and less muffled. VOICE PROMPTS Make a connection. It's easy. Voice prompts talk you through Bluetooth pairing. You can connect to two devices—and the speaker remembers the eight most recently connected devices. WATERPROOF Plenty of speakers look waterproof. But SoundLink Micro stands up to water from the inside out. That's because we didn't rely on the outer shell to keep water from getting in. Instead, we used materials like silicone to create a seal around the technology inside. It's IPX7 rated. And exceeded.
