Frequently Asked Questions
How long does the battery really last at full volume outdoors?
How long does the battery really last at full volume outdoors?
At moderate outdoor volume, TerraSound Pro delivers up to 12 hours from its 3700mAh battery. At high volume in open air, expect 7-9 hours — still enough for a full beach day without hunting for an outlet.
Is it actually waterproof — and does it float if it falls in?
Is it actually waterproof — and does it float if it falls in?
Yes on both. TerraSound Pro's IPX7 rating means it survives full submersion up to 1 meter for 30 minutes. It also floats — so if it goes overboard at the pool, dock, or on a kayak, you're retrieving a working speaker, not a paperweight.
How long will the battery actually last?
How long will the battery actually last?
At moderate volume, TerraSound Pro runs up to 12 hours on a single charge. Unlike budget speakers where the battery swells or fades to 4 hours within a year, the 3700mAh cell is built for seasons of regular use — not just the first summer.
Is it loud enough for open outdoor spaces?
Is it loud enough for open outdoor spaces?
Yes. The 40W dual-driver setup is built specifically for open-air environments. You get full, clear sound with deep bass that carries even when there are no walls to help project it.
Can I connect two speakers for stereo sound?
Can I connect two speakers for stereo sound?
Yes — TWS (True Wireless Stereo) lets you pair two TerraSound Pro units simultaneously. The result is a wider soundstage with twice the output power for larger spaces and bigger crowds.
Will sand or water ruin the charging port over time?
Will sand or water ruin the charging port over time?
This is exactly what kills most outdoor speakers — the port flap tears, sand gets in, and charging fails. TerraSound Pro's port is sealed to IP6X standard so fine particles can't reach the internals no matter how many beach trips you take.
Does it really hold up in dusty or sandy conditions?
Does it really hold up in dusty or sandy conditions?
It does. The IP6X dustproof certification guarantees full protection against fine particles — sand, grit, and trail dust won't find their way inside or affect performance.
Why buy this instead of a $30 speaker on Amazon?
Why buy this instead of a $30 speaker on Amazon?
Because $30 speakers have a $30 lifespan. Check the 1-3 star reviews: sand in the port after one trip, battery dead by season two, connection dropping at 10 feet. TerraSound Pro is built to last multiple seasons, not just one.
