TechRabbit offers the refurbished Logitech Ultimate Ears Megaboom Bluetooth Speaker in Black for $139.99 with free shipping. That's the lowest price we could find by $20, although we saw it for $10 less with our April mention. It's IPX7-certified waterproof and features up to 20 hours of playtime per charge, 360° sound, and up to 100-foot range. It also connects to the UE Megaboom app for features like party control, musical alarm, and 5-band EQ. Deal ends July 16.

Note: A 1-year TechRabbit warranty applies.
