Short answer: the JBL Xtreme 4 for practicality, the Vifa Helsinki for midrange and treble quality. The Xtreme 4 has a removable battery but is high priced. The Helsinki is generally regarded as having the best midrange and treble of any battery powered Bluetooth speaker, provided you accept no TWS pairing and a hacked Vifa app to enable night mode.
The case for the JBL Xtreme 4: Removable battery. The catch: High priced.
What the Vifa Helsinki gets right: 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.
Buy the Vifa Helsinki. It is rated higher for sound quality, and the $139.05 saving on the JBL Xtreme 4 is not enough to make up the difference.
There is a real battery-life gap here: the JBL Xtreme 4 is rated for 24 hours, the Vifa Helsinki only 8 hours.
If water resistance matters to you, the JBL Xtreme 4 at IP67 (brief submersion) holds up far better than the Vifa Helsinki at no water resistance.

The Two Speakers In Full
JBL Xtreme 4: $309.95 Amazon B&H Photo Video eBay
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported.

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.
