Short answer: the Vifa Helsinki for sound quality, the W-King T9 for loudness and battery. The Helsinki is 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 Android app to enable night mode. The T9 counters with 80W, 106dB max volume, 24-hour battery life and a power bank, but peaks in the upper mids make it sound harsh.
On the Vifa Helsinki side: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. The tradeoff: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good.
The case for the W-King T9: 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range. The catch: Peaks in the upper mids which makes it sound a bit harsh.
Buy the Vifa Helsinki. It is rated higher for sound quality, and the $319 you would save on the W-King T9 does not close the gap.

The Two Speakers In Full
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.
