JBL Xtreme 4 - Blue arrives as a rugged and powerful stereo portable speaker designed for all-day music, combining bold styling with IP67 protection for reliable outdoor use.

With a dedicated woofer (7 cm) and dual tweeters (2 cm each), the JBL Xtreme 4 delivers a balanced frequency range from 44 Hz to 20 kHz and a clear signal-to-noise ratio of 80 dB, producing room‑filling sound with 30 W RMS woofer power and an additional 20 W allocated to the tweeters for detailed highs.

Designed for wireless freedom, this speaker uses Bluetooth 5.3 (A2DP, AVRCP) for stable streaming and supports multipoint connectivity so you can switch between devices effortlessly. A USB Type‑C port provides both charging and USB output, and the speaker includes USB Power Delivery compatibility for fast recharging.

The built‑in 9444 mAh (68 Wh) Li‑Ion battery offers up to 24 hours of playback on a single charge and recharges in about 3.5 hours when using a compatible 15–60 W USB‑C charger. The Xtreme 4 also doubles as a power bank, letting you charge a phone from the USB output while the party continues.

Durability is a key selling point: the IP67 dust‑ and waterproof rating means you can use the speaker at the beach, by the pool, or on rainy hikes without worry. The package includes a shoulder strap, USB‑C cable, power adapter and quick start guide so it’s ready to go out of the box.

At 297 x 149 x 141 mm and 2.1 kg, the speaker balances portability and robust construction, making it easy to carry yet heavy enough to stay stable on surfaces. Physical controls are handled via buttons for straightforward volume and playback control, and an on/off switch provides simple power management.

Typical use cases include outdoor parties, beach days, small gatherings, and travel where dependable battery life and water resistance matter. The JBL Xtreme 4 is ideal for users who want powerful, wireless stereo sound in a durable, portable package with the convenience of fast USB‑C charging and power bank functionality.
