#1 in our rankings · Best overall

Best for: Open-plan rooms, patios, and parties where guests stand all around the speaker, not just in front of it.
Our recommendation
Buy the JBL PartyBox 310 if you want maximum forward punch, a dramatic light show, and a proven big-event box. Buy the Sony SRS-XV800 if your guests gather all around the speaker, you want the longest battery, or karaoke controls matter most. Both fill a large garden; the choice is about coverage shape versus forward impact.
Sound coverage
The 310 fires sound forward with great punch, so a crowd facing the speaker hears a powerful, direct mix. The XV800 spreads sound front and rear through five tweeters, so guests behind the speaker hear voices and treble far better. For a stage-style setup, the JBL wins; for a mingling crowd, the Sony wins.
Battery and charging
The XV800 leads with a 25 hour battery and a 10 minute quick charge for up to 3 hours, which is a genuine rescue feature. The 310 offers 18 hours, which still covers a long night, but it has no equivalent quick-charge trick, so a forgotten charge hurts more.
Lights and karaoke
The 310 has the more dramatic synced light show, which suits a party atmosphere, while the XV800 has subtler ambient lighting but stronger karaoke controls with echo and key adjustment. Karaoke-first buyers should lean Sony; atmosphere-first buyers should lean JBL.

Strengths and limitations
JBL PartyBox 310
Strengths
- The 240 watt output gives genuine headroom, so the speaker stays clear at party volume instead of straining at its limit from the first song.
- An 18 hour battery life means the party does not end early, and mains power keeps it going longer still when a socket is nearby.
- Wheels and a telescopic handle make a heavy speaker genuinely movable, so one person can roll it from house to garden without a second pair of hands.
Limitations
- At around 38 pounds it is heavy to lift, so stairs and car boots need planning even though rolling it on flat ground is easy.
- The size dominates a small room, and the light show can feel much for a quiet evening, though the lights can be switched off.
- Bass boost at maximum volume can overwhelm vocals in a small space, so the bass setting needs matching to the room, not just leaving on full.
Sony SRS-XV800 X-Series Party Speaker
Strengths
- Omnidirectional sound from five tweeters front and rear spreads music around the speaker, so guests behind it hear more than muffled bass.
- A 25 hour battery is among the longest here, and a 10 minute quick charge gives up to 3 hours of playback, which rescues a forgotten charge.
- Wheels and a handle plus mic and guitar inputs make it a genuine all-rounder for karaoke, TV sound boosting, and outdoor parties alike.
Limitations
- At about 40 pounds it is one of the heaviest speakers here, so even with wheels it needs care on stairs and in car boots.
- The broad sound spread trades some forward punch for coverage, so listeners directly in front may prefer a more directional speaker.
- The size and feature set carry a premium outlay, so buyers with small gatherings pay for coverage they may never use.

Questions, answered
Which is louder?
The JBL 310 feels louder directly in front, thanks to its forward-firing 240 watt design. The Sony spreads its output more widely, so it can feel quieter head-on but more even across a whole patio.
Which is easier to move?
Both have wheels and handles, but the 310 is slightly lighter at about 38 pounds against the XV800 at about 40 pounds. In practice both need care on stairs, and neither is a one-hand carry.
Which works better as a TV speaker?
The Sony, thanks to its optical input and TV Sound Booster feature. The JBL can play TV audio over Bluetooth or aux, but it has no equivalent TV-focused mode.
