Short answer: the JBL Partybox 300 ranks #8 of 50 party speakers by sound quality at $300; the Sony GTK-XB60 ranks #48 at $299. With prices this close, go by the sound-quality ranking rather than the cost.
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 Sony GTK-XB60 offers: 60W powerful sound performance with extra-bass technology for deep, punchy output. 2x 5.12” woofers + 2x 1.97” tweeters. Up to 14 hours battery at reasonable levels (3 hours at full volume with extra bass and lamps). NFC support, flashy party lights, app control for light moods. Pair two XB60s for wider soundfield. Works as mini PA system with RCA/USB/mic ports. Watch for: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning
Buy the JBL Partybox 300 if sound quality is the priority over the price, or the Sony GTK-XB60 if the price is the priority over sound quality.
The Sony GTK-XB60 is not a sound-quality pick. It sits near the bottom of the 50 party speakers; there are better options higher up.
