Short answer: the JBL Partybox 330 for a fuller low end. The Sharp PS-929 delivers 180W and can pair two units over TWS, but its bass is not very deep. The 330 has a convenient handle and wheels, though its sound is nearly identical to the 310 and Stage 320 despite the power bump.
Buy the JBL Partybox 330. It is rated higher for sound quality; the Sharp PS-929 is no longer sold new.
If water resistance matters to you, the JBL Partybox 330 at IPX4 (splashing) holds up far better than the Sharp PS-929 at no water resistance.

The Two Speakers In Full
JBL Partybox 330: $629.95 Amazon B&H Photo Video eBay
Older models: the JBL Partybox Stage 320 (ranked lower, rated 4.6/5), the JBL Partybox 310 (ranked lower, rated 4.5/5) and the JBL Partybox 300 (ranked lower, rated 4.3/5).
Pros: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. It supplies a little more power than the JBL Partybox 310 and JBL Partybox Stage 320, while reviewers report better midrange clarity than the older JBL Partybox 310 and the same deep party-speaker bass.
Cons: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational. JBL removed the dedicated mic gain/control knobs found on earlier models, a real drawback for frequent karaoke use. Do not upgrade from a JBL Partybox 310 or JBL Partybox Stage 320 just for the higher watt figure.
