• Sound like a pro easily: Be the DJ with Bluetooth streaming, make announcements clearly with the microphone jack or jam out with your favorite keyboard or guitar. Built in Tone Match processing and Auto EQ make it easy to get great sound anywhere.
• Place and play: Like having an audio engineer right there with you, the S1 Pro's built-in sensors and multiple aiming positions make sure you have optimal sound in nearly any position - whether it's on the ground, on its side, tilted back or elevated.
• Grab and go: The S1 Pro was designed to be out and about. The lightweight, rugged enclosure with the built-in handle makes it easy to carry and transport.
• Included lithium-ion battery lets you bring big sound wherever the fun is, with up to 11 hours of playback. Use the Quick Charge function when you need to recharge in a hurry.
• Download the Bose Connect app to access additional options and features like Party Mode, so that you can wirelessly stream audio to a second system for even more sound.
