Monster S150 Portable Bluetooth Speaker, 24W Stereo, IPX7 Waterproof

At 14.6 x 5.5 x 7.2 cm, the Monster S150 is a compact portable speaker that fits easily into a travel setup or on a tabletop at home. Its black metal-and-plastic enclosure keeps the design straightforward for everyday listening.

With 24W stereo sound, bass boost and a dynamic driver, it brings music to a room, gathering or outdoor outing. The IPX7 waterproof rating adds practical reassurance for listening near water.

Bluetooth 6.0, TWS pairing, RGB lighting and a built-in microphone make the S150 more versatile than a speaker focused on playback alone. Need sound to reach a larger space? Pairing with a compatible speaker can expand the stereo setup.

Everyday use

With a phone or tablet, you can play music wirelessly, switch to a supported input, or take a call through the built-in microphone.

The package includes the waterproof Bluetooth speaker, a power cable and a quick start guide. The guide provides a starting point for setting up the speaker, while the cable supports its power needs.
