Casio CT-S300 Reviews

Good starting keyboard for the price

By Victor
Rated 4 out of 5
Date: 2026-10-08

Second one I've purchased, so each son's family had one (both had some piano training as children). A good starter keyboard for the price. Having full size keys was important as well as their being sensitive to force/velocity applied to help transition to professional instruments if desired. Don't expect professional keyboard build, but fully adequate with reasonable care. Same for voices. Pianos are OK, but don't expect a professional Yamaha sound out of the small speakers (haven't tried professional headphones to see if they do better). Does better with the synths where you don't have real acoustic instruments to compare with. Playing keys far beyond the range of the actual musical instrument will obviously not provide good results, but that is user error. Being battery capable and having an integral carrying handle should make it fully portable to take to a party anywhere. This package did not come with a sustain pedal or stand, but those are available if desired. Happy with it while understanding its limitations. Several videos available about it are online that may help getting the most out of it.
