Short answer: the Samsung MX-ST50B for balance, the Soundcore Rave 3S for karaoke. The Samsung at $300 sounds reasonably balanced, though its bass is not as deep as a Partybox 110 or other higher-ranked speakers. The Rave 3S at $349.99 includes two wireless microphones and a remote, but adds some upper-bass and upper-mid boost.
Buy the Soundcore Rave 3S. It is rated higher for sound quality, and the Samsung MX-ST50B is discontinued, so it is only available used.
If battery life is a priority, the Samsung MX-ST50B is rated for 18 hours versus 12 hours for the Soundcore Rave 3S.
