Outdoor sound for open spaces

The Soundcore Boom 2 A3138 is a portable outdoor speaker built around a 2.1 channel layout with a dedicated 4‑inch subwoofer. It delivers 80 watts of total power and a 45 hertz low‑frequency response so bass stays audible across patios, campsites and beaches. An IPX7 rating and floatable chassis mean it survives immersion and won’t sink if knocked into water.

Power and connectivity on the go

Bluetooth provides a 10‑metre operating range for phone or tablet playback without cables. The built‑in power bank can top up a mobile device while the speaker runs, and fast charging restores the speaker’s own battery quickly. Up to 24 hours of playtime on a single charge supports full‑day outings where mains power is unavailable.

Tailored EQ and light show

A customisable EQ lets listeners shape the tonal balance to suit different genres or environments. Integrated RGB lighting adds a visual element that syncs with the music for evening gatherings. Both features are controlled through the companion app, giving direct control over sound profile and light patterns without extra hardware.
