Samsung MX-ST50B Sound Tower Party Speaker

Samsung MX-ST50B Sound Tower – bi-directional party speaker with 240W output

The Samsung MX-ST50B is a Sound Tower party speaker built to fill a room, a terrace or a small hall with sound that spreads in two directions at once. Instead of firing from one face like a conventional portable speaker, its bi-directional design pushes audio from both sides of the tower, so guests hear the music clearly wherever they are standing. With 240 watts of output, a dedicated Bass Booster mode and a splash-resistant IPX5 body, it is made for gatherings where a small Bluetooth speaker simply runs out of breath.

It sits in Samsung’s Sound Tower range as the step up from the smaller MX-ST40B, adding output and presence while keeping the same party-first formula: LED lights that move with the beat, karaoke-ready microphone inputs, and the Sound Tower app for controlling the show from a phone.

Sound that works the whole room

The bi-directional layout is the MX-ST50B’s defining idea. Two sets of drivers fire from opposite sides, widening the sweet spot so the music does not collapse into a single loud spot in front of the speaker and silence behind it. The 240W amplifier stage gives it genuine headroom for outdoor use, and Bass Booster adds the low-frequency weight that party tracks are built on. A bi-directional tower also keeps vocals and detail present at lower volumes, which suits background music during dinner before the party properly starts.

Built for parties, indoors and out

An IPX5 rating means splashes from the pool side or a passing shower are not a crisis, and the tower format keeps the footprint small relative to the sound it produces. The built-in battery delivers up to 18 hours of playback, so the speaker can run a full event away from a power socket. LED lighting is built into the body and can be switched between ambient, party and off modes, with finer control and DJ-style effects available in the Sound Tower app.

Karaoke and connections

Two microphone inputs make duet karaoke straightforward, and a separate guitar input lets a player plug in and play along. Bluetooth Multi Connection keeps two phones connected simultaneously so friends can take turns queueing tracks without re-pairing, while Group Play can link additional Sound Towers for larger spaces. USB playback covers pen-drive playlists, and the tower can connect to a compatible Samsung TV over Bluetooth for movie nights.

If you host often and want one speaker that handles background music, full parties and karaoke without a rack of separate equipment, the MX-ST50B is the practical pick. It trades the ultimate fidelity of a hi-fi system for spread, stamina and fun — exactly the right trade for a party speaker.
