The S181 is an 88-key fully weighted digital piano designed to mimic the touch and response of an acoustic piano with hammer action and multi-level touch sensitivity. It includes a furniture-style stand and triple pedal system for a realistic playing setup at home. With 280 tones, 260 rhythms, 110 demo songs, and built-in recording, it supports learning and everyday practice. Wireless connectivity and multiple ports (including MIDI and headphone/audio connections) make it easy to pair with apps and external devices. Dual keyboard mode supports teacher-student practice and duet-style learning.
