Short answer: both are discontinued, so this only matters if you are buying used. Used, the Samsung MX-ST50B is the better pick: it ranks #25 of 51 party speakers by sound quality (rated 3.6/5), against #42 (rated 2.5/5) for the Sharp PS-929. If you want one new, the Sony ULT Tower 5 ranks #5 at $348. The Sharp PS-929 has been replaced by the Sharp XParty Sing PS-931.
The Samsung MX-ST50B is the better-sounding, longer-running option. A splash resistant party tower with two woofers, karaoke input, app EQ, and linking for up to ten speakers. It is rated for 18 hours of battery against 13 for the Sharp PS-929. It is rated IPX5, while the Sharp PS-929 has no water resistance. It supports aptX Bluetooth, which the Sharp PS-929 lacks. The tradeoff: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
The Sharp PS-929 is the lighter option. A battery party speaker with two woofers, a Super Bass button, lights, mic and guitar inputs, and a wired mic included. At 19 lbs (8.6 kg) it weighs noticeably less than the Samsung MX-ST50B at 26.2 lbs (11.9 kg). The catch: Bass extension is only about 60Hz at -10dB, so it lacks deep bass.
Buy the Samsung MX-ST50B only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Sony ULT Tower 5 instead.
