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.

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.

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.

This particular product is extremely loud so far it has worked extremely well and I like it a lot. I listen to my music extremely loud, but I don't even use this most of the time at its loudest setting because it is that loud and clear and clean. I think it is worth the money absolutely.

I picked up the JBL Xtreme 4 mainly to have something dependable to use during long work shifts, and it’s been exactly that. Battery life has been the standout for me. I consistently get well over 10 hours of playtime, and I’ve never had it die on me in the middle of a shift, which was my biggest concern going in. Sound quality holds up well throughout the day without needing constant adjustment, and it feels solid enough to handle regular use without me worrying about it. Setup was simple, and once it’s going, it just works without any fuss. Overall, it’s been a dependable speaker that fits perfectly into my daily routine at work. If you need something you can turn on and trust to last all day, this one has earned its place.

Bass so good it makes my mom mad $300 maybe a little steep but great sound quality and good quality overall.

The default JBL sound signature is fantastic. This is my first bluetooth speaker in years and I was impressed by the app/settings and auracast functions, so much so that I bought a smaller charge 6 shortly after getting this unit. The auracast has been amazing for hosting
