Xtreme 4 - Portable Waterproof Speaker - Black | Next level massive JBL Pro Sound, Up to 24 hours of playtime plus 6 hours with Playtime Boost, Convenient shoulder strap

The JBL Xtreme 4 is a fantastic choice if you want a big, bold portable speaker that can handle just about anything you throw at it. It delivers powerful sound with deep, punchy bass and clear highs, thanks to its dual drivers and passive radiators. Even at higher volumes it stays clean and dynamic, making it suitable for parties, backyard barbecues, or filling a large room with music. One of its biggest strengths is how tough and practical it is. The Xtreme 4 is IP67 waterproof and dustproof, so poolside splashes, rain, or a day at the park are no problem. It has a rugged build with rubber bumpers and a carry strap, which makes it much easier to move around than most bulky speakers in its class. Battery life is another highlight. You get long all-day playtime depending on volume and usage, and it can even charge your devices through its USB port, so it can act like a power bank when needed. It also supports multipoint Bluetooth and the ability to link with other compatible JBL speakers for a much bigger soundstage. This makes it very flexible for both casual listening and larger gatherings. Overall, the JBL Xtreme 4 is loud, durable, and convenient. If you are looking for a premium portable speaker that can live outdoors, power a party, and stand up to real-world use, it is very easy to recommend.

A definite upgrade from my charge 5 beautiful full sound. Easy to use as pushing the power and pressing play. Bluetooth is top notch stays connected across my big house and look at this setup. Looks simple but has amazing functionality and versatility. And this is a JBL known for durability. I definitely recommend the rubberized case mostly for the style and the boombox style handle but it adds to the already outstanding durability of these speakers. Never used the strap yet but its definitely high quality and my favorite feature i saved for last. This has a removable / replaceable battery. I love that its future proof. Btw you get 30 extra watts of sound when its plugged into the supplied power cord. Thats a big sound boost when its in my bedroom or patio room... I really enjoyed my jbl charge 5 but this jbl extreme 4 is miles ahead on pure sound and bass quality. I would highly recommend this speaker to anyone wanting huge sound in a still portable package. Jam on everyone. Thanks for reading

I purchased the JBL Xtreme 4 (Blue) using Amazon’s monthly installment plan, which made the purchase much more manageable. From the moment I turned it on, I was blown away by the powerful sound and deep bass. Whether I’m using it indoors or outdoors, the audio quality is rich, loud, and balanced—exactly what you'd expect from JBL. One of the standout features is the 24-hour battery life. I’ve used it for beach days, backyard gatherings, and long work sessions without needing to recharge. The fact that it doubles as a power bank is incredibly convenient — I can charge my phone on the go without carrying extra gear. The IP67 waterproof rating gives me peace of mind around water. I’ve used it near the pool and even in light rain with no issues at all. The PartyBoost feature is great too — I paired it with a friend’s JBL speaker and the sound coverage was phenomenal. The build quality feels rugged and premium, and the blue color gives it a stylish, modern look. It’s portable but packs a serious punch when it comes to audio performance. Overall: If you're looking for a high-quality portable speaker with top-tier sound, long battery life, and versatile features, the JBL Xtreme 4 is a great investment — and Amazon’s installment option made it even easier to own. ✅ Great sound ✅ Long battery life ✅ Waterproof & durable ✅ Power bank function ✅ Easy to carry and pair Highly recommended!

Title based on performance and weight. I found it ideal for carrying and use poolside or on my boat. Connects effortlessly to Apple 11 Promax phone - I would assume much newer apple phones should be fine as well. With right placement options you could even use this as a powered speaker for an apple TV box (works with my gen 2) in order to bypass anemic flat TV built in speakers. The bass is clean and decent. I mean - it’s not going to rip the plaster off the walls but it’s still very good for what it is. I have two Boombox 2’s that I have been use as a stereo pair poolside. If it’s just me at pool this thing is fine. My music taste is full spectrum - Black Sabbath thru The Dan Thru Bach and Beyond.

This speaker is a decently sized speaker in between being considered huge and being considered small. In terms of sound quality it has great everything; vocals, bass, soundness, etc. It gets so loud that I have considered buying a subwoofer and pairing it with the speaker so that it sounds fuller. It does have good bass by itself but when cranking the volume up it slightly disappears. If you’re more worried about the difficulty of use don’t be, this is a simple speaker to pair up and start listening to music. Additionally the speaker itself has some standard controls like “play/pause”, “volume up”and “volume down”. In conclusion this is a great speaker but I would buy it only if it was $250-280. Bought mine for $250 and I am not disappointed, I’ve used it for the beach and pool party’s. (Have Xtreme 3 and it is also a great speaker if you find it on discount and you dont want the newest you won’t be disappointed. )

This thing is awesome no dought, tho being a rebuild I think wasn't all the way properly inspected there are random crackles but very rare. Over all I am very happy wit this purchas 9/10.

I tried Megaboom 4, Ult Field 5 and This Xtreme 4. The Xtreme 4 was the only one that met my expectations in my use case. My use case is inside a truck cab on the dashboard. I wedge this between the front and side windows giving room on both ends for the bass and aiming the front speakers nearly right at me. It sounds fantastic even though my ears are only a couple feet away. Punchy bass. Loudness and clarity blows away the Megaboom 4. When playing it outside it sounds great a few meters away. The battery lasted over 12 hours at mid to high volume playing bassy songs. Meaning it hasn't died on me yet using it for 12 hour work shifts. Minus one star because the carry strap is way too long. A simple handle would do me just fine. The ends of the speaker look dirty but it's someone's idea of cool design. Last negative is value for the money. I do love the bass reproduction. The bass about 35 seconds into Sir Mix A Lot "I'm Your New God". I can hear it on this clearer than other bt speakers. Not as clearly as on a pair of studio monitors at home but this Xtreme4 is relatively small. I am happy with this speaker. The Megaboom 4 might have been slightly better sounding with the 360 sound in enclosed spaces but if I wanted to play anything with bass I'd have to keep it at or below 50% volume and then couldn't really hear the music. At high volume the woofer was damaged and caused a permanent rattle. It also had bluetooth dropouts, maybe because the phone was less than a meter away. It didn't quite get loud enough to cover the engine sounds in a CDL vehicle but worked ok. The battery in it almost always lasted 10 hours at high volume. I returned the Megaboom 4. The Ult Field 5 sounded empty. It was ear piercing up close. I imagine it is intentionally designed for outdoor use with people several meters away. (A far field speaker) I do not recommend you try this one in an enclosed space or up close. The bass was lacking even when set to maximum. Returned.

I love this thing. I carry it everywhere. Battery lasts forever. I use it while gardening for several hours a day at moderate volume. Only needs charging every couple weeks. Played it pretty loud at the beach for 8 hrs, app said next day, 81% battery life left!

Se o seu objetivo é ouvir música em boa qualidade, ficará muito satisfeito. O som tem uma qualidade absurda, além do volume. Uma caixa compacta atende ambientes médios e grandes. Fiz um churrasco e ela deu conta de 8h evento e ainda sobrou bateria. Usei também com a TV, ficoi ok. Mas não é a principal função dela.

Léger et beau, en plus du son qui est dune clarté et la basse est tres bien pour la dimension de l'appareil. La charge de sa batterie qui dure la journée sans s'en préoccuper. Vraiment satisfait et ce n'est que le premier jour d'usage. Je compte l'utiliser au travail pour les exercices d'étirement en groupe avec de la musique rythmée, en camping et bateau plage. Facile a transporter comparé aux plus gros boîtier avec roulettes de 300wtts et plus.

Súper bien sonido la verdad. El tamaño es un poco grande pero es justo lo que buscábamos. Vivimos en un lugar abierto entonces las bocinas terminan to teniendo suficiente potencia. Está si se alcanza a escuchar bien. Tampoco es una fiestooooota como para treparle un buen perooo si se escucha muy bien. Hasta se la conectamos luego a la TV y suenan súper bien las pelis. Muy feliz con la compra.
