These are not really the same size class, and that is the honest framing here. The Demerbox DB2 ranks #48 of 70 boombox speakers at $400; the Vifa Helsinki ranks #1 of 75 large speakers at $400.
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 at $400 if you want a boombox speaker. Buy the Vifa Helsinki at $400 if you want a large speaker instead.

Pros: 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). Built from a Pelican case - nearly indestructible and waterproof (IP67). Multi-pair up to 6 units. Doubles as power bank and waterproof container.
Cons: Bass is not as deep as better speakers. Very overpriced.

Vifa Helsinki: $400 Amazon
Pros: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker.
Cons: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good. Not sure I can recommend this one generally these days, the Uboom L has 98% of the sound quality with more features and a way 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.
