Frequently Asked Questions
Is IPX6 good enough for beach use?
Yes — IPX6 protects against powerful water sprays and splashes and is generally sufficient for beach use where the speaker won’t be submerged. If you expect accidental drops into water, choose an IPX7-rated model that tolerates brief submersion.
Can these speakers charge a phone while playing music?
Yes. All reviewed models include USB power-out that functions as a power bank. Expect slower charging than a dedicated fast charger, but enough to top up a phone during a beach day. Check each model's battery capacity to estimate how many charges you can expect.
How do I keep sand out of the charging ports?
Look for speakers with covered or recessed ports and rubber flaps; always close port covers after charging. Shake out sand gently before sealing, and avoid placing the speaker face-down on sandy surfaces—use a towel or elevated surface instead.
