"Big Sound Under the Big Sky"
Anker Soundcore Sport XL - High powered bluetooth speaker with IP67 Waterproof design, 15-hours battery life, and powerful subwoofer.
I took the SoundCore XL Sport down the Smith River in Montana, a pristine 60-river mile float on blue ribbon fishing waters through central-western Montana. We were on the river for five days without civilized contact, camping along the shore every night. The Soundcore Sport XL played all day in the boat and all night in the campground, charging overnight from an Anker PowerCore powered by solar energy collected during the day. I dunked it in the river multiple times without any performance issues at all. Thanks to Anker for packing amazing sound into this nearly indestructible product.
