Short answer: the Vifa Helsinki, and it’s the class leader. It ranks #1 of 120 large speakers at $449; the Motion X600 ranks #19 at $159.99, $289.01 less.
Our notes call the Helsinki generally regarded as the best midrange and treble sound quality of any battery-powered Bluetooth speaker, though it has real quirks: no TWS pairing, and a hacked, Android-only app is needed to enable its night mode properly.
The Motion X600 is far fussier for far less money. Our notes say it needs a different EQ for each volume step, and even with the recommended Oluv EQ applied, the bass still isn’t very deep and the sound stays a little unnatural.
Buy the Helsinki if the sound quality is worth the premium and the app quirk doesn’t bother you. Buy the Motion X600 to save $289.01 and accept the ongoing EQ work.
If water resistance matters to you, the Soundcore Motion X600 at IPX7 (brief submersion) holds up far better than the Vifa Helsinki at no water resistance.
