Introducing the Casio CT-S300 portable keyboard

Casio introduced the world’s first electronic keyboard in 1980, bringing the gift of music to millions of people.

Nearly forty years later, the new Casiotone series changes everything once again, building on Casio’s renowned traditions of innovation, versatility and value for money.

The CT-S300 from Casio brings the finest of sound quality in their most portable keyboard yet. Never be held down by clunky keyboards or annoying wires again - simply add six AA batteries and make music, wherever you are. Perfect as a first keyboard or for those on the road, the Casio CT-S300 is a simple and fun keyboard, packed with some amazing features.

Please note, a power supply is not included and must be purchased separately. We recommend an EPA95100 9.5V adaptor, or 6 x AA batteries.

Superior Sound Quality

The CT-S300 uses a brand new speaker design together with new equalisation technology to deliver an exciting sound that belies its compact dimensions. With the audio input connection, you can plug in any media device and hear your music through the CT-S300 speakers. Also, the included 3.5mm stereo output socket allows you to plug in to practice any time of day, or night!

Lightweight and Compact

The new CT-S300 is designed to be the world’s most portable touch-sensitive, 61-note keyboard. New features such as a pitch-bend wheel, integrated carry handle, redesigned piano-shaped keys, longer battery life, smooth corners and a slim profile make this the perfect introduction to music.

Streamlined, easy-to-use interface

The CT-S300 features a simple, intuitive interface, offering an organised layout with fewer buttons by using both a full dot LCD screen and dial. It is also equipped with a home button that lets users return to the original screen at any time, providing speedy navigation which is perfect for new users, and brilliant in both primary and early secondary classrooms.

Impressive sound from such compact speakers!

Despite its small size, the CT-S300 produces clear, balanced sound across the full frequency range, thanks to 13 cm x 6 cm oval speakers with strengthened magnets and an equaliser that adjusts in tandem with the volume. Even at low levels, the tone remains crisp and detailed—ideal for classroom use without overwhelming volume. Alongside the crisp sound, the piano-style keys with touch response help young learners develop proper playing dynamics, responding naturally to the strength of each keystroke.

Packed with fun educational features

Fun learning modes such as Dance Music Mode allow students to experiment with beats and textures, building creativity and rhythm skills while keeping them engaged. With 12 specially designed Dance Music Voices, even a beginner can create exciting, layered tracks with just a few button presses. The My Setup button is perfect for lesson environments, allowing students to store their preferred sounds and rhythms—ready to recall instantly at home for consistent practice. If you're looking to bring some added nuance, consider connecting the SP-20 sustain pedal too.
