Sony ULT Tower 5 vs JBL Partybox 300

Last updated: October 5, 2026

Short answer: the Sony ULT Tower 5. It ranks #5 of 44 party speakers by sound quality (rated 4.5/5) at $448 and is still sold new; the JBL Partybox 300 ranks #10 (rated 4.3/5) and is discontinued, so it is only an option used.

Sony ULT Tower 5 vs JBL Partybox 300

The Sony ULT Tower 5 is the lighter, tougher choice. At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. At 28 lbs (12.7 kg) it weighs noticeably less than the JBL Partybox 300 at 35.3 lbs (16 kg). It is rated IPX4, while the JBL Partybox 300 has no water resistance. It supports LDAC Bluetooth, which the JBL Partybox 300 lacks. Watch for: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.

What the JBL Partybox 300 does well: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. The tradeoff: Hard to carry, too tall, drags on the ground.

Buy the Sony ULT Tower 5. It is rated higher for sound quality and still sold new, while the JBL Partybox 300 is discontinued.

Sony ULT Tower 5 ranking card

Pros: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. AudioTribe’s first impressions praise its deeper bass and clearer sound than the JBL PartyBox Club 120; it also has USB-C and USB-A, RCA, balanced XLR and mic inputs for DJ and karaoke use.

Cons: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance. Its single-woofer, two-tweeter layout lacks the Tower 7’s 360-degree rear-driver array, and the reviewer describes the sound assessment as first impressions rather than a controlled measurement comparison.
