While you lounge on the beach, a campsite, or your own backyard, wouldn’t it be more exciting if you listen to some awesome music? The problem is, inclement weather and accidents tend to happen. For partying outdoors with no worries, get yourself a waterproof Bluetooth speaker, like JBL's Flip 5, Charge 4, and Xtreme. They are now available on Walmart at awesome discounted prices.
