Portable Bluetooth speaker for outdoor

The Monster S520 is a compact active speaker built for music and hands-free calls wherever you go. Its IPX7 waterproof rating means it survives rain, splashes and brief submersion up to three feet for thirty minutes. A built-in lanyard lets you hang it from a backpack, bike or cart. Bluetooth 6.0 provides a wireless link up to fifty feet.

Check your device supports Bluetooth 6.0

The speaker only receives audio wirelessly, so confirm your phone, tablet or laptop pairs with Bluetooth 6.0. No wired audio input or auxiliary port is provided. The package includes a USB Type-C power cable but no wall charger, so you will need a compatible USB power source. Ensure you can recharge via Type-C before extended trips.

IPX7 waterproof housing

The sealed enclosure resists water, sweat and dust during showers, beach days or camping. A universal Type-C port enables convenient recharging from power banks, laptops or car ports. The integrated strap loop offers a secure attachment point for carabiners or the supplied lanyard, keeping the speaker accessible during hikes, rides or poolside use.
