Which Party Speaker Should You Buy? 8 Compared

RBE top pick

JBL PartyBox 720

Check price on Amazon See why it wins Compare all

The JBL PartyBox 720 is the most complete large-party speaker - deep bass, big output, a real light show, and battery-or-AC flexibility, all on wheels. The SOUNDBOKS 4 is the pick if portability, ruggedness, and all-day battery matter more than lights.

These are not pocket Bluetooth speakers. Most are the suitcase-to-refrigerator-sized boxes built to fill a backyard, a driveway, or a hall with sound, alongside a few smaller battery speakers people cross-shop against them. We looked at eight models you can buy in 2026: the JBL PartyBox 720, the SOUNDBOKS 4, the Marshall Bromley 750, the Sony ULT TOWER 10, the LG XBOOM XL9T, the Bose S1 Pro+ Wireless PA System, the Ultimate Ears HYPERBOOM and the Tribit StormBox Blast 2. Three are easy recommendations for a large party, one is superb but tethered to a wall outlet, three are smaller speakers that suit a particular kind of gathering, and one is a fine speaker that runs out of headroom next to the big boxes.

RBE top pick

JBL

JBL PartyBox 720

Buy it

The most complete big-party all-rounder: huge sound, real bass, and it rolls to the party on its own wheels.

Best for: Anyone who wants one speaker that does loud outdoor parties, karaoke, and deep bass without compromise.

$$$ · premium

Why we like it

• Big woofers deliver deep, room-filling low end that independent testing consistently ranks among the best in its class
• Runs on battery or AC, so it works off-grid and need not die mid-set at a longer party
• Built-in wheels and a sturdy handle make its considerable weight manageable
• Elaborate synced light show plus mic and instrument inputs for karaoke or a small performance

Know before buying

• Heavy and bulky - you roll it, you don't casually carry it up stairs
• Battery life at high volume is measured in hours, not the marathon a SOUNDBOKS delivers

SOUNDBOKS

SOUNDBOKS 4

Buy it

The go-anywhere loudness king - lighter than the other big boxes, brutally loud, and it runs all day on swappable batteries.

Best for: Festivals, beaches, and off-grid events where portability, ruggedness, and raw volume matter more than lights or gimmicks.

$$$ · premium

Why we like it

• Rated up to 126 dB - owners and independent testing agree it cuts through open air and large crowds like nothing else its size
• Swappable battery packs are rated up to 40 hours at mid volume (about 6 at full), and a fresh pack keeps it going
• IP65-rated electronics, a powder-coated steel grille, and silicone corners make it the most rugged, throw-it-in-the-van big box here
• At roughly half the weight of the other big boxes, it is the only full-size one you can realistically carry to a beach or festival site

Know before buying

• No light show and no included mic; it has XLR/TRS inputs for a mic or guitar, but it is a loudspeaker first, not a party-in-a-box
• Bass is punchy and tight rather than the deep sub-rumble the JBL and Sony can produce

Marshall

Marshall Bromley 750

Buy it

The highest published output here, 40-plus hours on a replaceable battery and real stage lights, on a 52.7 pound frame that rolls.

Best for: Hosts who want the JBL's lights and inputs with SOUNDBOKS-style endurance and will pay flagship money for both.

$$$$ · flagship

Why we like it

• Marshall publishes a maximum of 127 dB at 1 m from two 10 inch woofers, two 5.25 inch mid-ranges and four tweeters arranged for 360 degree sound.
• A replaceable LiFePO4 battery rated for 40+ hours, a 20 minute quick charge good for about 5 hours, and mains power when an outlet is near.
• Two XLR/6.35 mm combo inputs, three stage-light presets, IP54 dirt and splash resistance, and built-in wheels and handles.

Know before buying

• At 52.7 pounds it is far heavier than the SOUNDBOKS; you roll it, you do not carry it.
• The most expensive speaker in this comparison.
• IP54 is a splash rating, a step below the SOUNDBOKS's IP65 electronics.

Check price on Amazon Read our detailed assessment ↓

Sony

Sony ULT TOWER 10

It depends

The best-sounding of the bunch with the deepest bass - but it's a wall-powered tower that never leaves home.

Best for: House parties, karaoke nights, and home-theatre use where mains power is always available and sound quality is the priority.

$$$ · premium

Why we like it

• Independent testing praises the most refined, natural tuning of any speaker here, with the deepest bass thanks to a large woofer and its ULT bass modes
• Loads of party features: 360-degree light show, an included wireless microphone for karaoke, and a TV/optical input for movie nights
• Genuinely enormous, room-filling output for indoor spaces and covered venues

Know before buying

• AC power only - there is no battery, so it is useless anywhere without an outlet
• Very heavy and tall; the wheels help, but this is a stay-put centrepiece

Amazon had no buyable listing for this when we last checked. The link still works if it returns.

Bose

Bose S1 Pro+ Wireless PA System

It depends

A compact battery PA built around microphones and instruments, which Bose rates for audiences up to 50 rather than a full yard party.

Best for: Gatherings where people will talk, sing or play through the speaker as much as they stream music.

$$$ · premium

Why we like it

• A 3-channel mixer with two mic/instrument channels, ToneMatch presets and reverb makes it the strongest option here for toasts, speeches and live music.
• It weighs 14.4 pounds, Bose rates the battery at 11 hours, and it works in multiple positions, including as a floor monitor, with Auto EQ for each.
• Optional wireless RF transmitters for mics and instruments pair to it and store inside the speaker, and a line out with Sub EQ lets you add a powered subwoofer.

Know before buying

• Bose rates it for audiences up to 50, a smaller crowd than the big boxes are built for.
• No light show and no published weather rating.
• No woofer size or maximum output is published, and the wireless transmitters are sold separately.
• Bluetooth range is listed at only 30 feet.

Check price on Amazon Read our detailed assessment ↓

Ultimate Ears

Ultimate Ears HYPERBOOM

It depends

A 13 pound battery speaker with a 24 hour rating and four inputs, sized for a medium party rather than a large one.

Best for: Medium gatherings where long battery life in something one person can carry matters more than big-box volume.

$$ · mid-range

Why we like it

• Ultimate Ears rates the battery at up to 24 hours with a 2.6 hour charge, in a 13.01 pound body with a pull-out strap.
• It takes two Bluetooth sources plus an auxiliary and an optical input, and switches between them without pausing the music.
• Two 114 mm woofers, two tweeters and two large passive radiators with adaptive EQ, behind an IPX4 splash rating.

Know before buying

• Ultimate Ears publishes a maximum of 100 dBC, a lower figure than the 126 and 127 dB SOUNDBOKS and Marshall state.
• No lights and no microphone or instrument input, so karaoke is off the table.
• Bluetooth is listed as 4.2 to 5.0, older than the Marshall and Tribit.

Find it on Amazon Read our detailed assessment ↓

Tribit

Tribit StormBox Blast 2

It depends

The budget pick with lights, mic inputs and an IP67 rating, built for a backyard group rather than a field.

Best for: Backyard and beach groups on a budget where water resistance and karaoke matter more than big-box headroom.

$ · budget

Why we like it

• Tribit rates it IP67, the highest ingress rating any speaker here publishes.
• Up to 30 hours of playtime from a 79.92 Wh battery, plus a USB-A port that charges a phone.
• Two 6.35 mm mic inputs with adjustable reverb, wireless mic support, an app-controlled light show and stereo or party pairing.

Know before buying

• Output drops from 200W on AC to 180W on battery, and Tribit publishes no maximum sound level.
• At 15.76 pounds with a top handle and no wheels, it is a boombox rather than a big box.
• The 30 hour figure assumes 50% volume with XBass and lights off, and USB-C charging takes about 12 hours.

We'd skip it

LG

LG XBOOM XL9T

Skip it

A likeable, feature-packed tower - but for a genuinely large party it runs out of headroom before the others do.

Best for: Patios, garages, and mid-size gatherings where a full big-box PA would be overkill - but not the main choice for a large party.

$$ · mid-range

Why we like it

• A fun pixel-LED display and karaoke support make it a lively mid-size party speaker
• The lightest tower here with wheels and a telescopic handle, plus a built-in battery
• Costs noticeably less than the JBL, SOUNDBOKS, and Sony

Know before buying

• Less loud and less deep than the JBL, SOUNDBOKS, and Sony - owners note it struggles to fill truly large or open spaces
• Marketing power figures overstate real-world output compared with the JBL, SOUNDBOKS, and Sony

How we judged the field

We don’t run our own lab. Instead, we synthesize independent testing, expert reviews, and aggregated owner reports to find where the consensus lands - and where it splits. For large party speakers, a handful of things separate the genuinely great from the merely loud, so those are what we weighted.

• Usable loudness, not marketing watts. Peak-power numbers are close to meaningless across brands. What matters is how much clean, undistorted volume a speaker delivers before it starts to sound harsh - its headroom at party levels.
• Bass that you feel. For parties, low-end depth and impact do a lot of the emotional work. Woofer size and cabinet design tell you more here than any spec sheet.
• Getting it there. A speaker that fills a field is no use if you can’t move it. We looked at weight, wheels, handles, and whether it runs on battery.
• Ruggedness and weather. These live outdoors and get bumped. Ingress ratings and build quality decide whether it survives the season.
• Party extras. Lights, karaoke mics, and app control aren’t essential, but they’re often the reason people buy these instead of a bookshelf system.

All eight models below are current and buyable in 2026. Where a name has changed - JBL’s older PartyBox 710 is now the 720, for instance - we use the current model.

This is the one most people should get. With big woofers and plenty of power, the PartyBox 720 produces the kind of deep, room-filling bass that independent testing repeatedly ranks near the top of the category, and it goes plenty loud for a large backyard. Crucially, it runs on either its internal battery or wall power, so it works off-grid and keeps going on wall power if you’re near an outlet. It rolls to the party on built-in wheels with a sturdy handle, which makes its considerable weight a non-issue in practice. Add a genuinely impressive synced light show plus mic and instrument inputs, and you have a single box that covers loud outdoor music, karaoke, and everything in between. Owners consistently describe it as the do-it-all choice, and we agree.

If portability and endurance top your list, the SOUNDBOKS 4 is the pick. Rated up to 126 dB, it is astonishingly loud for its size and, by owner accounts, cuts through open-air crowds as well as anything here. It is also the only big box you can realistically carry - at 35.5 lb, far lighter than the JBL, Sony and Marshall - and the most rugged of them, with IP65-rated electronics, a powder-coated steel grille, and silicone corners. The killer feature is its swappable battery system: up to 40 hours at mid volume (about 6 at full), and you can swap in a fresh pack to keep going. The trade-off is focus. There are no lights and no included mic, though XLR/TRS inputs take a mic or guitar, and its bass, while punchy and tight, doesn’t rumble as deep as the JBL or Sony. For festivals, beaches, and anywhere without power, that’s a trade worth making.

The Marshall Bromley 750 comes closest to combining the JBL’s party features with the SOUNDBOKS’s endurance. Marshall publishes a maximum sound pressure level of 127 dB at 1 m, from two 10 inch 150W woofers, two 5.25 inch mid-ranges and four tweeters placed to fire forward, sideways, backward and up for what Marshall calls True Stereophonic 360 degree sound. The battery is a replaceable LiFePO4 pack rated for 40+ hours, 20 minutes of charging gives about 5 hours, and it also runs from mains power. Two XLR/6.35 mm combo inputs take a mic or guitar, and it adds three stage-light presets, Bluetooth 5.3 with Auracast, and wired AUX and RCA inputs. The costs are weight and price. It weighs 52.7 pounds, so the built-in wheels and handles do real work, its IP54 rating sits a step below the SOUNDBOKS, and it is the most expensive speaker here. It suits hosts who want one box for long outdoor parties with lights and a mic.

On pure sound, the Sony is arguably the best of the original four we compared. Independent testing praises its unusually natural, refined tuning for a party speaker, and its large woofer plus dedicated ULT bass modes give it the deepest low end in this group. It is also the most feature-rich: a 360-degree light show, an included wireless microphone for karaoke, and a TV/optical input that lets it double as a home-theatre and movie-night speaker. So why “it depends”? Because it is AC-only. There is no battery at all, which makes it useless anywhere without an outlet, and as a very heavy, tall tower, it is very much a stay-put centrepiece. If your parties are at home and you value sound quality above all, it’s superb. If you ever need to leave the house, look elsewhere.

The Bose S1 Pro+ Wireless PA System is a different tool from the party boxes above: a portable PA that also streams music well. Its 3-channel mixer gives two full channels for a microphone or instrument, with ToneMatch presets and reverb, plus a third for Bluetooth or a wired source, and optional wireless RF transmitters pair to it and store inside the speaker. It works in multiple positions, including as a floor monitor, with Auto EQ adjusting for each, and a line out with a Sub EQ setting lets you add a powered subwoofer later. It weighs 14.4 pounds and Bose rates the battery at 11 hours. The limits are spelled out on the same page. Bose describes it as suited to audiences up to 50, it publishes no woofer size, maximum output or weather rating, there are no lights, and Bluetooth range is listed at 30 feet. Buy it if your gatherings involve toasts, karaoke or a guitar; for raw volume across a big yard, the JBL or SOUNDBOKS does more.

The Ultimate Ears HYPERBOOM sits between a portable speaker and a party box. It weighs 13.01 pounds, stands 14.33 inches tall, has a pull-out strap rather than wheels, and Ultimate Ears rates the battery at up to 24 hours with a 2.6 hour charge on its own power supply. Inside are two 114 mm woofers, two tweeters and two large passive radiators with adaptive EQ, and the IPX4 rating covers spills and splashes. The input list is its best party trick: two Bluetooth sources, an auxiliary input and an optical input, switchable from a button or the app without stopping the music. The limits are just as clear. Ultimate Ears publishes a maximum of 100 dBC, a lower number than the 126 and 127 dB that SOUNDBOKS and Marshall state, though makers do not all measure the same way. There are no lights, no mic or instrument input, and Bluetooth is listed as 4.2 to 5.0. It suits patios and living rooms where carrying it matters more than covering a field.

The Tribit StormBox Blast 2 is the budget way into this category, and its spec sheet is more complete than its price suggests. Tribit lists an 80W subwoofer, two 45W mid-range drivers and two 15W tweeters with passive radiators, for 200W on AC power and 180W on battery. The IP67 rating is the highest any speaker here publishes, the 79.92 Wh battery is rated for up to 30 hours, and a USB-A port charges a phone. For a party it has two 6.35 mm mic inputs with adjustable reverb, wireless mic support, an app-controlled light show and stereo or party pairing with a second unit. The fine print matters. The 30 hour figure assumes 50% volume with XBass and lights off, USB-C charging takes about 12 hours against 5 on AC, Tribit publishes no maximum sound level, and at 15.76 pounds with a top handle it is a boombox rather than a big box. Buy it for a backyard or beach group on a budget; for a large crowd, the big boxes earn their price.

The XL9T is a likeable speaker - a fun pixel-LED display, karaoke support, wheels, a telescopic handle, and a built-in battery, all at a friendlier price than the JBL, SOUNDBOKS, and Sony. The problem is the context. Judged specifically as a large party speaker, it is less loud and less deep than the JBL, SOUNDBOKS, and Sony, and owners note it starts to strain when asked to fill a big or open space. Its headline power figure also flatters it relative to real-world output next to the JBL, SOUNDBOKS, and Sony. For a patio, a garage, or a mid-size gathering it’s genuinely good value - but if you specifically want to cover a large party, the extra spend on one of our top picks buys real, audible headroom. That’s why we skip it for this job.

Who should buy which

• Most hosts who want one speaker for everything: the JBL PartyBox 720. Deep bass, lights, karaoke inputs and battery or AC power on wheels.
• Festivals, beaches and off-grid events: the SOUNDBOKS 4. The lightest big box here, with IP65 electronics and swappable batteries rated up to 40 hours at mid volume.
• Long outdoor parties with no budget ceiling: the Marshall Bromley 750. 127 dB published, 40+ hours on a replaceable battery, stage lights and two mic inputs, if you can roll 52.7 pounds.
• Toasts, karaoke and live music: the Bose S1 Pro+ Wireless PA System. A 3-channel mixer with ToneMatch and reverb, rated by Bose for audiences up to 50.
• Medium gatherings where you carry the speaker yourself: the Ultimate Ears HYPERBOOM. 13.01 pounds, a 24 hour battery rating and four inputs, though with no lights or mic input.
• Tight budget, wet setting: the Tribit StormBox Blast 2. IP67, mic inputs and a light show for the least money, sized for a backyard rather than a field.

JBL PartyBox 720 vs SOUNDBOKS 4: which should you buy?

These are the two speakers most large-party hosts should be choosing between, and the decision comes down to a single question: how far from a power outlet do you party?

The JBL PartyBox 720 is the more complete package. It goes deeper on bass, brings a full light show and karaoke inputs, and its battery-or-AC flexibility means it adapts to almost any setting. Its weight is real, but the wheels make it a rolling problem rather than a carrying one. It is the better centrepiece for a fixed party.

The SOUNDBOKS 4 wins on everything mobile. It is far lighter, tougher, louder in raw terms, and its swappable-battery system is rated up to 40 hours at mid volume - so for festivals, beaches, and long off-grid events it is simply the more practical machine. What you give up is the lights, an included karaoke mic, and a little low-end depth.

Buy the JBL if your parties happen in one place and you want lights and karaoke; buy the SOUNDBOKS if you’re constantly on the move and endurance matters most.

What to look for

• Real headroom over quoted watts. Trust owner and independent-testing impressions of clean, undistorted loudness rather than peak-power marketing figures.
• Woofer size for bass. Bigger woofers (or multiples of them) do more for party low-end than any equalizer setting.
• Battery vs AC. Decide honestly whether you’ll ever be away from an outlet. If yes, prioritize battery life and swappable packs; if no, a mains-only tower gives more sound per dollar.
• Wheels and handles. Above about 15 kg, transport design matters as much as the speaker itself. Look for real wheels and a solid telescoping handle.
• Weather rating. An IP6x or IPX4 rating handles splashes and mist; do not count on any of these in a downpour, so plan for cover.
• The extras you’ll actually use. Karaoke mics, light shows, TV inputs, and app EQ vary widely. Pick the feature set that matches how you’ll really use it rather than the longest list.

Our final take

For most people throwing large parties, the JBL PartyBox 720 is the right buy: it combines deep bass, big clean volume, a proper light show, karaoke inputs, and battery-or-AC freedom in a box that rolls itself to the party. The SOUNDBOKS 4 is the one to get instead if you’re mobile - lighter, tougher, louder, and able to keep going on swappable batteries, at the cost of lights and karaoke extras. The Sony ULT TOWER 10 is the connoisseur’s choice for a home that never needs a battery, delivering the finest sound and deepest bass of the group. And the LG XBOOM XL9T is a fine, affordable mid-size speaker that we’d only skip because, for a genuinely large party, the others simply do more. Match the speaker to where you’ll actually use it, and any of the top three will keep a crowd moving.
