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.


Before ordering SleepPhones® Classic or the Lightning adapter:
- Look closely at the ports on your device. Determine if you have a 3.5mm port.
- Check the original box your device came in. You may have received an adapter with your purchase.
-
Identify if you have an Apple or Android device. Device type determines which adapter you may need.
- iPhones without 3.5mm ports will need 3.5mm to Lightning adapters
- Androids without 3.5mm ports will need 3.5mm to USB-C adapters
