Short answer: the Sony ULT Tower 5. It ranks #5 of 51 party speakers by sound quality (rated 4.5/5) at $348 and is still sold new; the Sharp PS-929 ranks #42 (rated 2.5/5) and is discontinued, so it is only an option used. The Sharp PS-929’s replacement, the Sharp XParty Sing PS-931, is rated 2.5/5 at $160.
The Sony ULT Tower 5 is the better-sounding, longer-running choice. A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It is rated for 20 hours of battery against 13 for the Sharp PS-929. It is rated IPX4, while the Sharp PS-929 has no water resistance. It supports LDAC Bluetooth, which the Sharp PS-929 lacks. Watch for: It has a shorter 20-hour battery claim than the Sony ULT Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
The Sharp PS-929 is the lighter choice. 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 Sony ULT Tower 5 at 28 lbs (12.7 kg). The catch: Bass extension is only about 60Hz at -10dB, so it lacks deep bass.
Buy the Sony ULT Tower 5. It is rated higher for sound quality and still sold new, while the Sharp PS-929 is discontinued.
