Amazon deal: $20 waterproof Bluetooth speaker will have you singing in the rain

Enjoy your music in wet places like the shower, by the pool or while you’re kayaking with a bright green waterproof portable Bluetooth speaker. The Mengo AquaCube Waterproof Portable Bluetooth 4.1 Speaker is on sale for half off its list price — for $19.95 with free shipping for Amazon Prime members.

This is a super compact, clear and powerful-sounding 3W speaker that is about the size of a clementine. It only weighs 2.4 ounces and features Bluetooth 4.1 technology. It is water resistant and can be submerged in water up to 3 feet, but for no longer than 10 minutes if you want it to keep working when you rescue it.

Take this speaker to the pool, into the shower, on a boat or anywhere else most speakers don’t dare tread. It also offers the ability to answer, hang-up, redial or refuse calls with the push of a button, and it comes with a no question asked, hassle-free one-year warranty.
