Harman Audio offers the factory-refurbished JBL Clip+ Splashproof Bluetooth Speaker in eight colors (Black pictured) for $18.99 with free shipping. That's $11 under our refurb mention from August and the lowest total price we've seen in any condition. (It's the best deal today by $11 as well.) It features a built-in carabiner, speakerphone function, and rechargeable battery (which supports up to five hours of playtime.) A 1-year JBL warranty applies.
