Austin portable bluetooth speaker from Klipsch packs a Texas-sized punch in a mini, handheld package. The 4.1" square by 1.7" deep speaker houses a 1.5" full-range speaker and dual passive radiators for deep and resonating bass. If you need more sound, pair up to 10+ together in Broadcast Mode. Take it with you anywhere, as it's so water and dust-resistant that it can be submerged in water, plus it has a built-in flexible strap for attaching it to a bike, golf bag, and more. Stream music from up to 40' away for up to 12 hours on a full charge, and thanks to reverse charging, you can use some of that power to keep your phone alive in a pinch.
