The EarFun UBOOM X is a portable Bluetooth speaker built for the outdoors, combining a promised 30 hours of playback with 80W of stereo output driven by a 4-driver design and EarFun's JumboBass tuning. It features Bluetooth 5.3 connectivity, a TWS/Party Connect mode that lets you link up to 50 units, and full IP67 waterproof and dustproof protection. It has a built-in LED light show and a carry handle and strap for portability, and it offers the ability to act as a power bank for your other devices. The UBOOM X is positioned as a rugged, feature-rich party speaker that's just as at home indoors as out.
Our Verdict
The EarFun UBOOM X is decent for listening to music. Its sound profile is generally pretty balanced, if a little uneven in the bass and mid-range. That's to be expected from an affordable, boombox-style speaker, and shouldn't deter you from considering this if you're shopping at this price point. The gentle roll-off of the highest frequencies ensures the sound isn't too harsh or piercing, and this speaker gets loud enough to fill large rooms with sound, which is impressive for its form factor, though you do sacrifice some low-end punch at the highest volumes. It comes with over 30 EQ presets so you can find a sound you like, and includes some specially designed presets that take advantage of both EQ and dynamics processing. That said, we think the default sound is a great starting point. You'll want to position this speaker facing you, as its forward-facing drivers can sound a little muffled if you're positioned behind them.

Reaches up to 95 dB at max volume.
Forward-facing drivers means sound varies with your listening position.
Noticeable compression at max volume.
The EarFun UBOOM X is passable for watching movies and videos. Out of the box, it offers a pretty balanced sound profile that you can change via its 30+ presets. And it gets loud enough to fill a large living room with sound, although sounds like kick drums will lose punch in the bass range at max volume. It can playback stereo audio without downmixing to mono, so stereo effects like long reverb tails in epic synth movie scores will still sound exciting. That is, so long as you're positioned in front of the speaker, as its forward-facing design means the sound is noticeably different from behind. Unfortunately, even with its included Video Mode activated, latency is still high, so you may notice lip-sync issues. That said, different apps and devices compensate for latency in different ways.

The EarFun UBOOM X is satisfactory for listening to podcasts. It offers a mostly accurate mid-range, so voices sound life-like and are easy to understand. It gets loud enough for you to hear from across the room, and the included carrying strap means you can take it from room to room while cleaning up before a party. Unfortunately, its somewhat limited directivity means the sound can change noticeably depending on where you’re sitting or standing in relation to the speaker.

The EarFun UBOOM X doesn't come with a built-in voice assistant, but you can control your phone's built-in Siri, Google Gemini, or Google Assistant using the speaker's mic. The mic does an amazing job picking out your voice from a few meters away and in noisy environments. So you can set it up near your grill station while hosting a garden BBQ and control your phone hands-free. However, you should try and keep the speaker facing you, as its front-facing drivers sound slightly muffled when you're listening from behind it.

The EarFun UBOOM X is good for use outdoors. It has a great build quality, with an IP67 rating that will keep the rain and dust out during park hangs. It feels sturdy and has a handy carrying strap, so you can easily carry it around with you or hang it from a nearby tree branch. With a battery life that lasts around 39 hours off a single charge, you can take this speaker on a camping trip without worrying about the battery dying. It has a decently balanced sound profile that gets loud enough to soundtrack a garden hangout, though it lacks the bass to get your friends dancing to the thump of a techno kick drum. Since it has forward-facing drivers, you'll also want to be positioned in front of it for best results. While it lacks multipoint pairing, its Bluetooth connection has a good range, so you can wander away from the speaker without the music dropping out.

Popular Speaker Comparisons
The EarFun UBOOM X sits in the same incredibly competitive price range as popular portable speakers like the Anker Soundcore Motion Boom Plus, the Tribit StormBox Blast, the JBL Flip 7, and the Ultimate Ears MEGABOOM 4. This price range tends to serve two different niches that aren't always compatible with one another: loudness and portability. In terms of output volume, the EarFun is closest to the Anker and Tribit. They share a boombox-style design and get loud enough to fill larger rooms with sound. Compared to these, the JBL and Ultimate Ears are much more portable and easier to toss in a bag, but they can't get as loud. Where the EarFun really shines is battery life: it offers a remarkable 39 hours of continuous playback time, which easily surpasses all the others. You can also use it as a battery pack to charge your other devices via USB and use it with your phone's voice assistant, making it a very versatile option.

The EarFun UBOOM X is a slightly better Bluetooth speaker than the Tribit StormBox Blast, with a couple of caveats. They're similarly sized boombox-style portable Bluetooth speakers, but the EarFun is a bit lighter, making it easier to carry, and also has a sturdier, dust-proof build quality. You can also use your phone's voice assistant with the EarFun, and it has a slightly longer battery life. On the other hand, the Tribit supports Bluetooth multipoint with up to two devices, and its soundstage feels a bit more immersive.
The EarFun UBOOM X is a better portable boombox-style speaker than the Anker Soundcore Motion Boom Plus, though the differences are slight. The speakers are very similar in size and price and have almost identical max volumes. That said, the EarFun has a battery life that's almost four times as long as the Anker, and its built-in mic does a much better job picking up your voice in noisy environments. The main reason to choose the Anker is its support for Bluetooth multipoint, allowing you to connect your phone and laptop to the speaker simultaneously.
The EarFun UBOOM X and the Anker Soundcore Motion X600 perform remarkably similarly, though each has distinct strengths. The Anker is smaller, making it easier to carry around with you. Subjectively, its design also looks better indoors, along with your other furniture. That makes sense, as it doesn't have a dust-proof rating, unlike the EarFun, which is sealed to dust ingress (although both will withstand submersion in water up to 1 meter in depth). The EarFun's battery life is roughly four times that of the Anker, but its latency is noticeably higher. In general, if you're looking for a park hang companion, go with the EarFun, and if you want a portable speaker to carry with you from room to room, go with the Anker.
Though similarly priced, the EarFun UBOOM X and the JBL Flip 7 serve different use cases. The EarFun is a fairly chunky, boombox-style speaker. Its built-in handle makes it portable enough to carry in one hand, but it's not something you can easily toss in a bag like the JBL. That size difference affects how the speakers perform, too. The EarFun gets much louder and has a much longer battery life. On the other hand, the JBL's IP68 rating beats the EarFun's IP67, and it supports Bluetooth multipoint. It comes down to use case: if you need to pump up the jams by the hockey rink, the EarFun is the way to go, and if you need a nimble, versatile friend to accompany you on your travels, choose the JBL.
