The JBL BOOMBOX 3 Black is a stereo portable speaker designed to deliver powerful, room-filling sound from a compact cylindrical enclosure. It features a 2 cm tweeter and a stated frequency response spanning 40–20,000 Hz, providing coverage from deep low frequencies through clear highs. The speaker supports both wired and wireless connectivity, including Bluetooth with A2DP and AVRCP profiles, operating in the 2.4–2.48 GHz band. With a signal-to-noise ratio of 80 dB and a portable form factor weighing 6.7 kg, the unit is intended for versatile use in indoor and outdoor environments.

Advantages

The design combines stereo output with a single compact cabinet, enabling strong acoustic output while keeping the unit transportable. Wireless Bluetooth connectivity allows playback from smartphones, tablets and other compatible devices without a cable connection, while wired input ensures compatibility with legacy audio sources. A wide frequency range and a dedicated tweeter contribute to clearer high frequencies and fuller low-end reproduction compared with typical small speakers. The cylindrical shape and black finish offer a neutral aesthetic that integrates into varied settings.

Use Bluetooth within the recommended 2.4 GHz band and keep the source device within a reasonable line-of-sight distance to reduce interference.
