AOMAIS Sport II IPX7 Bluetooth Speaker, $33 with code AOMAISF2

Most inexpensive Bluetooth speakers you see include a single 5W driver, or maybe dual 5W drivers if you’re lucky. But the AOMAIS Sport II packs in a pair of 10W drivers, plus IPX7 water resistance (meaning it can actually be submerged to a point), and a 10 hour battery. Not bad for $33.
