Short answer: the Soundboks Mix. It ranks #34 of 51 party speakers by sound quality (rated 3.2/5) at $799 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 Soundboks Mix is the better-sounding, longer-running pick. A rugged, weatherproof party speaker with a swappable battery that runs all day at mid volume and fast USB-C charging. It is rated for 40 hours of battery against 13 for the Sharp PS-929. It is rated IP65, while the Sharp PS-929 has no water resistance. It links with other speakers (TeamUp, up to 5 speakers), which the Sharp PS-929 cannot. The catch: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble.
What the Sharp PS-929 does well: A battery party speaker with two woofers, a Super Bass button, lights, mic and guitar inputs, and a wired mic included. It plays in stereo from a single unit, unlike the Soundboks Mix. Watch for: Bass extension is only about 60Hz at -10dB, so it lacks deep bass.
Buy the Soundboks Mix. It is rated higher for sound quality and still sold new, while the Sharp PS-929 is discontinued.
