360-Degree Sound: Under the Hood

A dedicated woofer reaches around 94 dB and a full 360-degree driver arrangement spreads bass and mids evenly. On lawns and patios, the Outdoor Boost preset increases perceived loudness while keeping vocals clear.

Fill a small garden with substantial low end and intelligible dialogue, making music and podcasts equally enjoyable. Compact enough to sit beside a 2-litre milk carton on a picnic blanket, it stays unobtrusive while sounding large.

Mastering Outdoor Playback via IP67 Waterproofing

IP67-rated protection allows submersion to 1 m for up to 30 minutes, and the floatable construction keeps the speaker buoyant when it lands in shallow water. Dirt-resistance and drop-proof design tolerate typical beach and festival knocks.

Leave the speaker on wet sand or by the pool without constant worry about splashes or brief dunks. Carrying is straightforward using the built-in loop, so moving between deck, grass and shoreline stays effortless.

Adaptive EQ: The Professional's Verdict

Customisable EQ and presets live in the BOOM app, while the Magic Button remembers a sound profile even when the speaker is switched off; NFC pairing speeds Android connections. PartyUp links multiple units, expanding coverage across larger outdoor areas.

If you switch from indoor listening to an outdoor party frequently, then the presets keep clarity and impact without manual tweaking. Tailor sound quickly and scale up with other compatible speakers for fuller coverage.
