I certainly was not disappointed by either, in fact, it was quite a revelation that Casio had come this far with its digital pianos.

The WU-BT10 Bluetooth adapter adds Bluetooth Audio streaming and wireless MIDI connectivity to your Casio CT-S1.

Not only do I use this instrument when playing outside of the home, it now sits on its stand in my living room where I can play as long as I want while my husband watches his games, etc. Another decent option if you're looking for a piano-style entry-level keyboard, the NP-12 is lightweight and portable, and sounds great.

Designed to tailor itself to the demands of the beginning keyboard player whilst maintaining Casio's consistent excellence across their instruments, the Casio CT-S1 comes with AiX technology onboard. This lightweight, portable keyboard includes strap pins so you can jam anywhere you see fit — just add a strap and batteries, and you're all set.h2>
