Soundcore Select 4 Go Bluetooth Shower Speaker by Anker, IP67 Waterproof/Dustproof, Ultra-Portable Bluetooth Speaker, 20H Playtime, Floatable, Powerful Sound, Electronics for Outdoors/Home/Travel

I have like three of these bad boys around the house, the battery life on them is insane and they sound fantastic. www.amazon.com/Soundcore-Bluetooth-Waterproof-Dustproof-Electronics/dp/B0DB1753RZ/ref=sr_1_1_pp I paid $20 for my first one during Prime Day last year and then lucked out finding a 2-pack on clearance at Costco for the same price, highly recommend!

After a quick look in the sub, something like the Xiaomi Sound Outdoor 30 W or the Soundcore Select 4 Go would be fit for purpose, perhaps something priced inbetween?
