JBL Partybox 330 vs Samsung MX-ST50B

Last updated: September 26, 2026

Short answer: the JBL Partybox 330 for bass and battery power. It adds an optical TV input, USB-C lossless playback, dual mic and guitar inputs, a removable battery and 280W versus the 310 and Stage 320’s 240W, though its sound is nearly identical to those two despite the bump and it is very large. The Samsung MX-ST50B sounds reasonably balanced but its bass is not as deep as a Partybox 110 and it must be plugged in to reach higher volume.

JBL Partybox 330 vs Samsung MX-ST50B

Buy the JBL Partybox 330. It is rated higher for sound quality, and the $249.95 saving on the Samsung MX-ST50B is not enough to make up the difference.

JBL Partybox 330 ranking card

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.

Samsung MX-ST50B: $300 Discontinued Amazon eBay

Samsung MX-ST50B ranking card

Pros: A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. Hands-on reviews find it capable of clear, punchy sound and impressive output for indoor parties, while its 18-hour claimed battery supports more casual use away from mains power.

Cons: Output drops sharply to 90W on battery, so it needs mains power for its full impact. Bass is not as deep as stronger dedicated party speakers, and at 11.9kg its tall enclosure is less convenient to carry. It lacks TWS stereo pairing, so the Group Play feature favors shared party coverage rather than a conventional stereo image. Discontinued.
