Wow, this thing is loud. The bass is amazing. Great upgrade from the boombox three. I definitely recommend it.

This JBL Boom 4 is the party starter ! Bass is thumping, sound is clear, and battery life is lit – 24 hours of nonstop jamz! Waterproof, portable, and BOOMING loud. Perfect for beach vibes or backyard hangs

The boombox 4 is driven by the bass and excellent sound quality. If you have a charge 6 it pairs extremely well since this becomes the ultimate portable setup. Upgrading from the boombox 3 to boombox 4, is well worth the money.

The best stereo unite I’ve ever bought. The Aura cast is exceptional. I even bought two for stereo pairing. The only slight downside to Auracast, is that when using Auracast, you cannot fix the equalizer-sometime THE JBL UNIQUE SOUND CAN BE TOO BASS RICH FOR OTHERS AROUND ME.
Overall though a 5 star.

Love this boombox. I've listened to the Boombox 3 and then the 4. The difference is HUGE. I'd definitely recommend checking this out. I personally don't think you'll find better sound fir the money.

Amazing sound quality and battery life. Don’t hesitate to demo it. It is a keeper. Coming from an extreme 2 = no comparison. Very livhtweight for the amount of distortion free output
