MP3 Player Unique Needs

Hello all.

I have been struggling to find what I need. I teach a special education class in homeschool. We have a lot of unique needs and challenges. One of our students loves music music, and has communication barrier with a severe speech impediment. They have been inappropriate with their laptop, so I need to find an mp3 player that can access Wi-Fi and spotify at school, but either does not have internal speakers, or has the ability to turn off the internal via settings. This student will blast their very inappropriate music when upset.
