Worth it for the money (I used a coupon for 3000 but you can hear why it costs 12 000)

I had a JBL Boombox 3 and I have to say right off the bat that the Boombox 4 is noticeably lighter, which is a big plus - it's easier to carry around, you're not carrying around a cow like you used to. As for the sound, it's a real shift here: - the bass is more pronounced, thicker and has more kick, but it's not overdone - the sound is cleaner, no rattling or mess at higher volumes - even when you crank it up, it still holds its quality A big plus is the ability to adjust the bass in the app, where you can fine-tune it exactly to your liking. Plus: - the backlight can glow orange or white, which looks really good, especially in the evening - the battery is very solid, all day playing without stress - the connection is fast and stable, no dropouts Of course, it connects easily through the JBL app (JBL Portable / Ultimate), you can connect it to other JBL speakers and make a mess 😁

I got a Sonos Move 2 and a JBL Boombox 4.
I couldn't just choose based on reviews, I needed to hear how it sounded and how it was to live with.
After unpacking, I unfortunately fell in love with both. sound, design and workmanship. The JBL Boombox 4 is made to BE outdoors where the bass will rumble at the barbecue, on the construction site, at the cottage. I also found it generally louder, easier to use and quick to connect. I would probably get this if I were still a student, it would be perfect for me! I'd use it on everything from morning till night and get on everyone's nerves =-)
In the end I stuck with the Sonos Move 2. The reason is the style of use. It will be primarily on a daily basis in the office and in the apartment. I'm gonna take the max out to the party. 1x a year.
If I had a use for both, I'd keep both. This JBL just wasn't suitable for my needs. Compared to the Sonos, it has weaker mids that sound slightly tinny. But the volume of the whole Boombox somehow makes up for it in power in the other bands, and if I wasn't comparing between JBL/Sonos/5.1 sound system/headset, I wouldn't even think about it. Sometimes when he played longer, I found the whole sound pleasant. Just the bass was just too much for my taste in an enclosed space, even on a low setting: ) Rating by media type:
For Rock, DnB, Metal music it gets 4.5/5 (I think there is probably nothing better in such a compact package for closed spaces).
Pop, hip-hop, soft-electro 4/5
Movies 4/5
For video games 4/5 If I hadn't bought both and compared, I wouldn't have regretted the purchase at all.
Sound clarity
The bass has several levels of adjustment, and even the lowest has serious power
The design is beautifully clean, the materials and their joints are top notch
For its size, it is comfortable to wear behind the ear
ease of connection via bluetooth and quick response to the JBL app
Battery replaceability? Oh, my God!
Waterproof, the design begs for someone to pour beer on it and test it
Meanwhile, the price. In the discount brand ideal.
Bass, trumps other ranges. But only when used indoors. On the exterior, this is a HUGE positive.
