From $20

Dell offers the Ultimate Ears WONDERBOOM Portable Bluetooth Speaker in navy for $49.99 shipped. Normally around $70 at Amazon, this matches our last mention and is just pennies above the all-time low there. UE’s WONDERBOOM is a great Bluetooth speaker for jam sessions at the beach, in the backyard, or around a hot tub with friends thanks to its 10-hour battery and IPX7 waterproof certification. Rated 4.4/5 stars at Amazon.

We also spotted the higher-end Ultimate Ears BOOM 2 Bluetooth Speaker for $90.99 shipped (Reg. $110+). This is a must-have if you have a larger area to fill with sound, or need the longer 15-hours of battery time. Rated 4.3/5 stars.

If you don’t need IPX7 waterproof ratings or up to 15-hours of battery life, the OontZ Angle 3 Bluetooth speaker has an IPX5 rating and 12-hours of battery for $20 Prime shipped when you clip the on-page coupon. Rated 4.3/5 stars from thousands.
