Advantages

Compact and ultraportable design combined with surprisingly big, bass-forward sound. Podcast Mode enhances vocal clarity, while Outdoor Boost optimizes sound for open-air environments. Long battery life of up to 14 hours supports extended use. Robust IP67 durability protects against dust and water and allows the speaker to float. Easy wireless pairing lets you link two units for true stereo separation or increased volume. Made with a significant portion of certified post-consumer recycled plastic.

Keep the devices within the wireless range for stable playback, and rinse with fresh water after exposure to salt or chlorinated water.

Recommendations

If using near water, secure the speaker to avoid strong currents and avoid prolonged submersion beyond rated conditions. Do not attempt pairing with older WONDERBOOM 1, WONDERBOOM 2, BOOM, MEGABOOM, or HYPERBOOM models; use only WONDERBOOM 4 units for stereo pairing. Charge regularly to preserve battery lifespan and store in a dry place when not in use.
