    I used this as a speaker for a desktop PC and the sound is great. It's about the size of a packet of cigarettes and the Bluetooth works great. No issues and the sound is great, for it's size. Perfect for a small desk or room for radio listening, for the bathroom or YouTube watching. Perfect for travel too. I would recommend.

    Excellent sound for such a small device. It's impressed friends also, definitely a good purchase and great bang for buck with the good sound quality. Tempted to get another one to try out the pairing them as stereo speakers which sounds like a great feature but honestly they're loud enough you don't really need a 2nd speaker.

    Got this for work was thinking it wouldn’t be much good for ONLY €28 but damn it surprised me definitely worth it

    Brother has JBL Charge 5 now that probably blows the go4 out of the water but the go4 won’t let you down still very punchy bass is top notch top don’t be fooled like I was in size you won’t be disappointed

    It’s a good sound, it has good volume. You can sync it with other JBL speakers which is very interesting and good for a cheap surround sound system in your home. It does have a vibration sound when you hit a certain volume but that’s ok as I won’t use it at that volume. It has a power saving setting which removes the base from the equalisation which basically makes it sound like your phones speakers except for the volume. For good sound, don’t use this option. It’s an option for listening to long podcasts I would say. 4 stars as there are better speakers. I bought this one as it had a 30% discount.

    Kinda incredible

    Honestly very impressed. Does everything it says it does, yet I was still unprepared for how great it is. The size is quite small, easily fits in the palm of my hand, yet the sound it delivers is impressive. I've used this at home, in the car whilst driving, taken it outside, and thanks to it being waterproof, even hung it up in the shower. The battery life doesn't suffer with its small size either, delivering hours of music playback over Bluetooth effortlessly.

    Was so impressed by this little unit that I bought another one just so I could take advantage of the stereo pairing, which was a little tricky to get going, but once setup via the app has been rock solid since. Also played with the multi-speaker party mode, which was as easy to get going as pushing a button on the speaker, literally.

    This is easily comparable to more expensive portable speakers, delivering solid performance for a much better price. It's easy to use, and I dig the colours. Easily recommended.

    Piccola nelle dimensioni, sorprendente nel suono

    Full content visible, double tap to read brief content.

    Ero alla ricerca di una cassa Bluetooth compatta da portare al mare e la JBL GO 4 si è rivelata una scelta davvero azzeccata.

    La prima cosa che mi ha stupito sono le dimensioni, è davvero piccola, entra facilmente nello zaino o nella borsa mare e si trasporta senza alcun ingombro. Nonostante il formato così compatto, la qualità audio è sorprendente. Il suono è potente, pulito e ben bilanciato, con bassi decisamente migliori di quanto mi aspettassi da uno speaker di queste dimensioni.

    Per me è stato un valore aggiunto anche il fatto che sia certificata IP67, quindi resistente all'acqua e alla polvere. Al mare posso usarla senza preoccuparmi della sabbia o di qualche schizzo d'acqua, il che la rende perfetta anche per piscina o altre attività all'aperto.

    La connessione Bluetooth è stabile, l'autonomia è più che sufficiente per una giornata di utilizzo e l'app JBL Portable è semplice e intuitiva.

    In conclusione, mi ha davvero stupito soprattutto per l'eccellente qualità del suono in rapporto alle dimensioni ridotte. Se cercate una cassa portatile, resistente e facile da portare ovunque, questa JBL GO 4 è un acquisto che consiglio senza esitazioni
