Short answer: the JBL Partybox 300. It ranks #8 of 50 party speakers by sound quality at $300; the Ultimate Ears Hyperboom ranks #31 and costs $449.99, so there is little reason to consider the other one.
What the JBL Partybox 300 offers: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Watch for: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead.
What the Ultimate Ears Hyperboom offers: Strong audio performance with 2x 4.5” woofers, 2x 1” tweeters, 2x passive radiators. Up to 24 hours battery at 50% volume (3 hours at max). Adaptive bass compensation for wall-reflective environments. Dual Bluetooth pairing, aux and optical inputs, USB-out for device charging. IPX4 splash-proof. Sliding rubber handle and compact square design. Watch for: Very expensive for what it does, a bit dull and muddy sound. Not as loud as others in the class. Bass not as deep as a Partybox 100. External power brick for charging.
Buy the JBL Partybox 300. It ranks higher for sound quality than the Ultimate Ears Hyperboom and costs less, so the other one has nothing left to offer.
