Setup
1. Included Components
Your SleepPhones Wireless package includes:

2. Initial Charging
Before first use, fully charge your SleepPhones Wireless. The battery requires approximately 3 hours for a full charge.
- Locate the charging port on the Bluetooth module inside the headband.
- Connect the provided USB charging cable to the module and a USB power source (e.g., computer USB port, wall adapter).
- A red indicator light will illuminate during charging. The light will turn off or change color (depending on model) when fully charged.
A full charge provides up to 24 hours of audio playback.
3. Sizing and Fitting
Ensure you have the correct size for optimal comfort and sound quality. SleepPhones are available in Small, Medium, and Large sizes. The headband should fit snugly but comfortably around your head.

Adjust the internal speakers by sliding them along the headband until they are positioned directly over your ears. The Bluetooth module should typically rest at the back of your head, but can be adjusted for comfort.
