Short answer: the JBL Partybox Stage 320 on ranking, the Soundcore Rave 3S for karaoke extras. The Rave 3S includes 2 AA battery Wireless Microphones and a remote control plus AI voice removal karaoke, but it has some upper bass and upper mids boost and is not as deep in bass as a Partybox 110 or 120. The Stage 320 ranks #3 of 49 against #19 of 49.
