Portable speaker for outdoor use

The HEYSONG REVERB BT138P is a 16W Bluetooth 5.0 speaker built for beach, pool and kayak trips. Its IPX7 rating means it survives immersion in water, while the 5000mAh battery delivers up to 40 hours of playback. The compact blue chassis includes a lanyard for hanging on backpacks or bicycles. Stereo pairing lets two units play together for wider sound.

Simple setup with multiple inputs

Pairing over Bluetooth 5.0 is quick with phones, laptops or MP3 players. A 3.5mm AUX cable and TF card slot provide wired and card-based playback without pairing. The speaker floats, so dropping it in water is not a problem. Common issues are forgetting to charge the battery fully before a long trip and leaving the AUX cable unplugged when Bluetooth is expected.

Check your source and charging gear

Ensure your phone, tablet or laptop supports Bluetooth 5.0 or earlier versions for best range. Have a USB power adapter ready because only the charging cable is included in the box. Verify that any TF cards you plan to use are formatted in a compatible file system. The mesh bag protects the speaker during transport but adds no waterproofing.
