Thanks for posting and welcome to the Community!
That's very strange that your son's SoundSport headphones are automatically lowering volume, this is absolutely something I would be more than happy to help you with. Could you please tell me specifically which model of SoundSport headphones he has? Has any troubleshooting been tried? If yes, what? Have you noticed this with all sources? Are you using a Bluetooth connection?
I look forward to hearing from you!
