Short answer: the Vifa Helsinki on measured sound quality, the Teufel Rockster Cross on price. The Vifa Helsinki ranks #1 of 78 large speakers at $449. The Teufel Rockster Cross ranks #21 at $199.99, $249.01 cheaper.
What the Teufel Rockster Cross offers: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver - better suited to rock and jazz. Nicer upper-bass detail than the JBL Xtreme 4. Punchy, well-controlled bass that suits rock music, unlike the Soundcore Boom 2 Plus’s overboosted, uncontrolled bass even at stock tuning. Clear, detailed audio with good vocal presence and solid Bluetooth codec support even a couple years after release. Watch for: Outdoor mode can sound somewhat harsh due to the 4khz peak. Not as deep or full-sounding in the bass as the JBL Xtreme 4.
What the Vifa Helsinki offers: 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. 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.
Buy the Teufel Rockster Cross if the price matters more than sound quality. Buy the Vifa Helsinki if sound quality matters more than the price.
Battery life favors the Teufel Rockster Cross: rated for 16 hours against 8 hours for the Vifa Helsinki.
If water resistance matters to you, the Teufel Rockster Cross at IPX5 (water jets) holds up far better than the Vifa Helsinki at no water resistance.
