Sven PS-670chat_bubble_outlineFrom real comments

Loud enough for home listening, but let down by plastic construction. At home it sounds loud, according to one buyer, but they wished the case were wood instead of plastic, arguing wood sounds much better and wouldn't add much to the price. This suggests the PS-670 satisfies casual indoor listening needs, but its plastic housing is seen as the main weak point holding back overall sound quality compared to a hypothetical wood-cased version of the same speaker.

Falls short of true party-speaker rivals like JBL Partybox. One buyer who expected a 'partybox killer' at 9,000 rubles instead called it disappointing and looked toward Partybox 310 as a replacement. Another commenter directly compared the PS-670 to the Sven 650 and preferred the 650's sound, then ultimately bought a JBL Partybox 110 instead, suggesting the 670 struggles to compete against dedicated party speakers on power and audio quality in side-by-side listening.

Two units can be paired for a bigger, bassier sound. At least one commenter noted that linking two PS-670 units together in a TWS-style setup produces more bass than running a single speaker alone, suggesting the model supports wireless stereo pairing. This could appeal to buyers wanting to scale up sound without committing to a pricier single large speaker, though only one comment in this set confirms the feature works this way.
