The SoundLink Micro Bluetooth speaker delivers crisp, balanced sound with unexpectedly powerful bass for its size. Thanks to its proprietary Bose technology, including a custom-designed transducer and passive radiators, it produces loud, clear sound - even outdoors. Micro is an IP67 waterproof speaker, plus it's fully dustproof. With its soft-touch silicone exterior and tear-resistant strap, this small Bluetooth speaker is built to tag along no matter the action. Attach it to your backpack or mountain bike, and don't worry if it falls on the ground. Enjoy up to six hours of play time with a lithium-ion battery that easily recharges with the included Micro-B USB cable. When on the go with this outdoor speaker, connecting is easy. You can seamlessly pair your phone or tablet with the Bose Connect app or follow the intuitive voice prompts, designed to make Bluetooth pairing simple. An integrated microphone allows you to take phone calls directly with your small portable speaker, while a multi-function button gives you access to your phone's voice assistant (Siri or Google Assistant). For even more immersive sound, pair SoundLink Micro with another Bose Bluetooth speaker, or connect it to a Bose smart speaker to extend your listening experience from inside the home to outside.
