Headphone Adapters
Do You Need an Adapter to Use SleepPhones® Classic?
Most wired headphones have 3.5mm plugs. SleepPhones® Classic headphones also have a 3.5mm plug. If your device has a standard round port, you should be able to use any headphones without an adapter.

A select group of manufacturers began eliminating the round 3.5mm port from their devices a few years ago. Anyone with those devices needs an adapter to use any headphones that have a 3.5mm plug.
