JBL Boombox 4 on Sale: Rare Deal on Amazon Brazil

What makes the JBL Boombox 4 worth buying right now?

The JBL Boombox 4 has reappeared on Amazon Brazil at R$ 2,179 when paying via PIX with the coupon code AMAZONTEM — a rare deal since the speaker had largely vanished from promotions for months, with discounts concentrated on older Boombox generations and lower-tier rivals.

What technology does the Boombox 4 pack?

The speaker runs on JBL Pro Sound combined with AI Sound Boost, which analyses audio in real time to optimize speaker performance, delivering stronger bass and lower distortion even at high volumes. The battery lasts up to 24 hours, with an extra 4 hours available through the Playtime Boost feature — enough for a full-day party.

Is it built for outdoor use?

Yes. The IP68 certification makes the Boombox 4 fully resistant to water and dust, so you can use it by the pool, at the beach, or anywhere outdoors without worry. The integrated handle makes it easy to carry despite its robust size.

What extras does it offer?

The Boombox 4 connects to multiple Bluetooth devices simultaneously, supports Auracast to pair with other compatible speakers for a bigger sound system, and doubles as a power bank — charging smartphones and other devices via USB while music plays.
