The JBL Xtreme 3 Portable Bluetooth Speaker is a large-format portable speaker, the size most people consider for outdoor use rather than indoor listening. The Xtreme 3 has two woofers, two tweeters, and two passive bass radiators, packed into a cylindrical fabric-wrapped body, with an IP67 rating for water and dust resistance and 15 hours of runtime per charge. PartyBoost, JBL’s multi-speaker pairing technology, lets you sync the Xtreme 3 with other PartyBoost-compatible JBL speakers for stereo separation or a larger group setup at parties.
A portable speaker that truly brings the bass no matter where you go
The Xtreme 3 produces greater usable volume than its smaller cousins in JBL’s Charge and Flip lines. If you are using it as a portable unit at your backyard barbecue, at the beach, or at a pool party, and you need to be able to hear your music over a wide-open area, then the additional drivers and increased cabinet size will help prevent distortion at high volume settings. Additionally, the dedicated tweeter and woofers produce better separation of vocals than you get from smaller speakers.
Since the Xtreme 3 is meant to be played outdoors, its IP67 rating is an important spec. It means the unit can remain submerged for 30 minutes at a depth of 1 meter without sustaining internal damage. So it can withstand a sudden downpour of rain or an accidental drop into a pool. Additionally, it’s sealed against sand, dust, and dirt, so it can withstand harsh conditions that would destroy an indoor speaker.
JBL includes a fabric carry strap with the Xtreme 3 that runs through both end caps of the speaker and clips together with a metal buckle. The strap has a bottle opener built into it for opening drinks at gatherings.
You charge the Xtreme 3 through a typical USB-C cord. The speaker also has a USB-A port that lets you charge a phone or tablet from the internal battery while music plays. For all-day events in places where wall outlets aren’t accessible, you can drain the speaker’s battery, powering both music and the occasional phone top-up.
You can adjust equalizer adjustments, firmware updates, and PartyBoost pairing on JBL’s iOS and Android apps. Voice assistant pass-through routes your voice commands through the paired phone, so they work the same way they do when using the phone directly.
The Xtreme 3 has dropped to $200 on Amazon, down from its original $330 price. That deal puts it in the same range as the smaller JBL Charge speakers. However, the Xtreme 3 has more drivers, longer battery life, and a noticeably bigger soundstage. For users who want a portable JBL with real volume for outdoor use, the Xtreme 3 at $200 is the strongest value in the company’s portable lineup right now.
