It is positioned as a top-tier product from 2021, aimed at users who need reliable portable acoustics for outdoor and field conditions (water and dust protection IP67). It is distinguished by an impressive nominal output power of up to 50 W, making it one of the loudest devices in its class.
The built-in battery with a capacity of 36.3 Wh provides up to 15 hours of autonomous playtime and allows the JBL Xtreme 3 audio system to be used as a high-capacity powerbank. It can serve as a power source for charging a smartphone, the battery case of portable TWS headphones, a navigator, an action camera, and such. Unlike the previous generation model (Xtreme 2), this speaker uses a more advanced Bluetooth 5.1 wireless interface, which is backward compatible with previous versions. Two smartphones or tablets can be connected simultaneously to one speaker via air. The JBL PartyBoost function allows connecting two identical speakers for stereo sound or multiple devices supporting JBL Connect. Two powerful bass woofers (70 mm) and two tweeters (20 mm) are responsible for signature bass sound.

The wide strap and excellent body balance make the speaker quite comfortable to wear. the case is protected according to the IP67 standard, it is not afraid of dirt, dust, water, and rubberized inserts are excellent shock absorbers in case of accidental drops and bumps. In a word, the name of the model and camouflage colors (there are also blue and black) speak for themselves - JBL Xtreme 3 was created for extreme recreation.
Listen, sing, dance
The output power of 50 W allows you to comfortably use the speaker for scoring an event with up to 10 people. Two 20mm tweeters, two 70mm woofers and JBL Pro Sound technology make the Xtreme 3 sound as expected, spacious, clear and dynamic, with assertive elastic lows and bright highs. The sound literally “rocks”. The party will be even louder if you synchronize two devices into a single stereo system using the Partyboost function.
