Big savings on a powerful portable speaker with deep bass

The JBL Boombox 3 usually costs $500, but right now it's selling for $300 on Amazon—that's a $200 discount. That price is close to what Apple charges for AirPods Pro, which is interesting because the Boombox is a much bigger device meant for outdoor use. Most speakers lose power when you switch from battery to AC power, but this one actually gets stronger—136 watts on battery and 180 watts when plugged in. That extra power shows up when you turn up the volume, giving you a noticeable boost in sound quality. This isn’t just any speaker. It has three drivers inside, including a dedicated subwoofer and passive bass radiators, which help it deliver deep lows. You can tweak the sound using the JBL app, adjusting bass, mids, and treble with a three-band equalizer. The default sound leans toward heavy bass, so if you prefer something more balanced, you’ll want to make changes. It’s also waterproof up to one meter deep for 30 minutes, though it won’t float—so dropping it in water is still risky.On the back, you’ll find a 3. 5mm AUX input for wired connections and a USB-A port that can charge small devices slowly. Bluetooth 5. 3 lets two people connect at once, making it easy to switch who controls the music. Charging takes about six and a half hours, which is standard for a speaker this size. The battery lasts up to 24 hours, so you can keep the music going all day without worrying about running out. One standout feature is PartyBoost, which lets you connect multiple Boombox 3 speakers together for even louder, deeper sound. The setup is simple through the JBL app, which also handles updates and sound adjustments. While the speaker is built for outdoor parties, its size and weight mean it’s not something you’ll carry around all day. Still, if you need something that can fill a backyard or poolside with music, this is a strong option at a good price.
