Party loud, party long

Got big plans that call for big sound? The JBL PartyBox 520 knows how to set the mood with a vibey lightshow and our biggest, boldest, thumping sound yet, powered by the all new AI Sound Boost tech to help get everyone moving and shaking. Our sound might be heavy but this speaker is easy to move, whether we're setting up in the backyard, by the pool, or that place where our friend just dropped a pin. Every move is smooth with the PartyBox 520's grippy handle and wide wheels that are ready to roll when you are. With up to 15 hours of playtime, you can host multiple parties before it's time for a recharge. And don't worry about any splashes or spills, this speaker is designed to withstand the most raucous parties - fouls and all. What’s better than one JBL PartyBox 520? Two or three or more! Pair them up or link with other JBL Auracast™-enabled speakers and take the party up a notch.

Electrifying sound with AI Sound Boost

Powerful sound to make your playlist shine. This sound is made to match your energy, so you feel like you're hearing each song performed live. Turn it up louder and your music will still sound great, as our new proprietary tech, AI Sound Boost analyzes your music in realtime to deliver maximum acoustic performance with less distortion.

Futuristic lightshow

Did someone say lightshow? Dance the night away with glowing light patterns and strobe effects that make any event a whole mood.

Up to 15 hours of play time

Keep the good vibes going on a single charge with up to 15 hours play time. And if 15 hours of nonstop jams isn’t enough, simply swap out the replaceable battery to keep the music going. Or charge for 10 minutes and get an extra 2 hours of play time. *Additional replaceable battery sold separately.

Great Quality and Elegant Look!
Color: 9-Silver-100
I ordered these 9 oz silver-trimmed plastic cups for a dinner gathering , and they turned out perfect. The silver rim gives them an upscale, classy look great for parties or more formal events like weddings. They’re sturdy and don’t feel flimsy at all, even when filled with ice and drinks. Guests complimented them several times, thinking they were real glass! Cleanup was easy since they’re disposable, but honestly, they’re durable enough to rinse and reuse if you want. Highly recommend for anyone looking to elevate their party setup without spending a lot.

Good quality choice
Color: 9-Gold-200
Very good quality for a wedding. Used for wine with a larger size for beer. Great match and not flimsy or thin quality. Can be washed and used again as the gold band doesn't wash off easily and they still look new after one use, or toss.
