Short answer: the JBL Partybox 310 for sound, the Soundcore Rave 3S for karaoke. The 310 has the deepest bass of any battery-powered speaker and the most balanced sound in its class, but it is very large and its daisychain will not work with non-JBL speakers. The Rave 3S bundles wireless microphones on 2 AA batteries, a remote and AI voice removal, though it boosts upper bass and upper mids and does not dig as deep as a Partybox 110 or 120.
The Soundcore Rave 3S’s strengths: Wireless microphones (powered by 2 AA batteries) and a remote control included, plus an AI voice removal feature for karaoke. But: it has some upper bass and upper mids boost, and doesn’t dig as deep in the bass as a Partybox 110/120.
Buy the JBL Partybox 330, the replacement for the discontinued JBL Partybox 310; it is rated higher for sound quality than the Soundcore Rave 3S.
Battery life favors the JBL Partybox 310: rated for 18 hours against 12 hours for the Soundcore Rave 3S.
