Pros: Very balanced sound. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo, app is buggy. Wireless TWS pairing is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has reliability issues more often than any other speaker

Minirig 4 with subwoofer: $290 Minirigs eBay
Pros: Very balanced sound. Finally USB-C charging. Deeper, more impactful bass than the old Sub 3. Subwoofer pairs wirelessly and can be placed anywhere in the room for extra bass. Fine-grained tuning via the app - 5-band EQ plus separate bass/treble and subwoofer controls. Sounded more accurate than the JBL Xtreme 5 in a side-by-side comparison, and the whole 2.1 setup is smaller and lighter than it.
Cons: Not stereo, app is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has reliability issues more often than any other speaker. Default out-of-the-box tuning sounds off and needs a custom EQ to sound its best.
