The Casio CTK-25550 is a 61-key compact arranger keyboard that’s meant to cater to the company’s usual targets – students.

As expected, it is packed with features that make it fun to play and easy to learn on, complete with a built-in learning system.

With 61 synth action keys, it has enough keys to play many of the classic songs that teachers love to teach to students.

And it gives you a lot of music making material to work with, from its 400 voices, to its 100 rhythms.

Adding to its practice friendliness is its headphone out for quiet practice, and aux input for playing along with your preferred tracks.

This keyboard ships with an AC adapter, but for portability it can run on 6 AA batteries.

If you’re looking for an affordable good quality starter keyboard, then the Casio CTK-2550 is where you should start.
