Cambridge SoundWorks Oontz Angle 3 Plus | $30 | Amazon | Clip the 21% coupon

Cambridge SoundWorks’ OontZ Angle is one of our readers’ favorite water-resistant Bluetooth speakers, but today, its larger brother has a great discount available.

So what are the advantages of the Plus model’s larger size? Obviously, it’s louder and has larger drivers, but the biggest difference you’ll notice is the battery life: 30 hours vs. 12 on the original. That’s reason enough to upgrade, especially at $30, after clipping the 21% (??) coupon on the page.
