Great Speaker for to take outdoor
I have owned the JBL Boombox 4 for a few days and must say it’s an impressive portable speaker. Out of the box, it felt rather premium and is also beautifully designed . It also has noticeable handle. Overall, it took approximately 3 hours to charge fully and weighs under 6 kg. The battery lasted over 24 hours when the volume was set to about 50 % and the EQ set to default. The speaker connected straight away to my device (didn’t require any additional app to install). The sound is crisp and offers deep thumping bass thanks to its 2 subwoofers, 2 tweeters and 3 radiators. When I turned the volume up, it filled in my whole living room and the sound stayed clear. I didn’t notice any distortion when it was set to 70%. Overall , I believe this is speaker is great for outdoor users and deserves a solid 4 star.

One of the best portable speakers
The JBL Boombox 4 is the latest high-end option in JBL’s popular consumer Bluetooth speakers, as a result it has some pretty big shoes to fill. With Deep bass activated, the JBL logos on the two massive passive radiators on each end of the speaker illuminate in a bright pulsing orange which then turns white when Punchy is enabled. It’s a lovely effect, I do however wish there was a way to turn it on independently of these bass modes, or even just the option to customize the colors of either. You can at least disable it entirely if you wish. Aside from your usual power, Bluetooth, play, pause, and volume controls, the rest of the major features are accessible via the excellent JBL app. This includes a range of equalizer settings plus a screen to create your own using a seven-band EQ.

Great product!
The JBL Boombox 4 delivers powerful, high-quality audio with impressive clarity and deep, well-balanced bass. It maintains excellent performance even at higher volumes, making it ideal for both indoor and outdoor use. Battery life is strong, and the waterproof design adds to its versatility. While it is relatively large and comes at a premium price, the overall sound quality and build make it a worthwhile investment.

jbl boom box 4
I'm quite pleased with the JBL Boombox 3 that I recently purchased. The sound is clean, strong, and has a deep bass that effortlessly fills the space. Even at maximum volume, the audio is clear whether I'm using it outside or indoors. The battery lasts for hours, making it ideal for travel or social gatherings. Additionally, I appreciate that it is waterproof and well-built, so I don't have to worry about using it outside. Pairing with my phone is made simple by the fast and reliable Bluetooth connection. All things considered, the JBL Boombox 3 is a high-end speaker with outstanding performance, robust durability, and a long battery life. Strongly advised for those searching for high-quality, powerful portable sound.

Amazing product!
A truly solid portable speaker. It's waterproof and dustproof, with powerful bass that delivers enhanced sound. Perfect for house parties, it's also great for outdoor activities. It's unmatched by my previous speaker. This one is unmatched! The battery lasts up to 34 hours and is replaceable. It's massive and solid, and the music plays clearly even with the bass turned up. My number one.

Great package and wonderful sound
Bought for the summer months and for taking out and about. Easy to carry with the handle. Delivers exceptional bass with the option of punchy or deep versions. Good EQ control through the app and easy to connect to bluetooth. Fairly large but manageable for travel short distances and has a good weight to it.
