Learning how to play the keyboard is easy with these Musical Instruments by Hey. Play. This keyboard kit comes with everything beginner musicians need to start playing, including a music sheet stand, keynote stickers, instructions, USB charging cable, a microph1, and a 3.5mm audio cable. The multi-functional digital piano is equipped with 60 demo songs, 200 rhythms, 200 t1s, a digital display, a teaching mode, audio input/output options, and recording and playback modes, ideal for children ages 8 and up. With the 3.5mm audio cable connected to the audio out port and an external speaker, the sound of the kids' keyboard and microph1 bypasses the internal speakers and plays through the external speaker, or the cable can be plugged into the audio in port with an external audio source, so that the audio is played through the keyboard's dual channel stereo speakers for convenient portability.
