Kawai ES100chat_bubble_outlineFrom real comments

Reviewers and owners rate the key action and piano tone as standout strengths for the price. Multiple commenters directly compared the ES100's action favorably to other digital pianos, including a Roland RD700NX and Yamaha models, calling it 'far superior' and unmatched for realistic feel and sensitivity at this price point. Others praised the grand piano sound sample specifically, with one buyer noting the 'nice quality' despite the simple, lightweight design. This combination of touch and tone is repeatedly cited as the reason people chose the ES100 over pricier alternatives.

Connectivity gaps around USB and line outs frustrate many owners. Several commenters note the ES100 has no USB port, requiring a MIDI-to-USB adapter to connect to a computer, and no dedicated line outs, meaning gigging musicians must run signal through the headphone jack with a TRS cable and splitter adapter. This complicates use as a stage piano and recording setups, with one user stating the lack of output lines was 'a shame' and another abandoning the brand over this limitation entirely.

The built-in speakers struggle with volume, clarity, and certain sounds. Owners report distortion at higher volumes, bass notes vibrating the plastic casing when playing organ sounds, and generally weak electric piano and organ tones despite the piano samples being praised. One user described the 2x7W speakers as 'not enough' and lacking a display, while another found real-world in-store volume noticeably quieter than in promotional videos, suggesting the speaker system is the piano's weakest component.
