Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Luna 2 ranks #22 of 138 medium speakers by sound quality at $199.95; the Vifa Helsinki ranks #1 of 77 large speakers by sound quality at $449.
What the Harman Kardon Luna 2 gets right: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it.
On the Vifa Helsinki side: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. Watch for: 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 Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Vifa Helsinki at $449 for a large speaker instead.
If water resistance matters to you, the Harman Kardon Luna 2 at IP67 (brief submersion) holds up far better than the Vifa Helsinki at no water resistance.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).

Vifa Helsinki: $449.00 Amazon eBay
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.
