Short answer: the Vifa Helsinki for sound quality, the Demerbox DB2 for battery life. The Helsinki is generally regarded as having the best midrange and treble of any battery powered Bluetooth speaker, though it has no TWS pairing, looks like a purse, and needs a hacked Vifa app for the night mode that makes it sound good. The DB2 runs 40+ hours, about 14 hours with phone charging mixed in, but its bass is not as deep as better speakers.
On the Demerbox DB2 side: 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). Set against that: Bass is not as deep as better speakers.
The case for the Vifa Helsinki: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. Set against that: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good.
Buy the Demerbox DB2 ($400) for a boombox speaker; the Vifa Helsinki ($449) suits a large speaker instead.
Water resistance is not close: the Demerbox DB2 is rated at IP67 (brief submersion), well ahead of the Vifa Helsinki at no water resistance.

Vifa Helsinki: $449.00 Amazon eBay
Pros: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. Measured bass extension of 48Hz (-10dB).
Cons: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good. This one is hard to recommend generally these days: the Uboom L has 98% of the sound quality with more features and a much cheaper price. There are mentions that the 2022 “new” version of this speaker doesn’t sound as good as Vifa was purchased by a Chinese company and laid off all the great sound engineers in the Austria office.
