Minirig 4: $200 Amazon
Pros: Modular, can easily attach a subwoofer. Finally USB-C charging. Dynamically changes sound based on forward facing or upward facing orientation
Cons: Calls itself splash resistant and has no official water rating. App is buggy. Wireless TWS pairing is buggy. A bit expensive. Has reliability issues more often than any other speaker
