Hi there! I understand that your Earjoy Intelligence earbuds won’t connect to the YWS Earphone app. Let’s work together to get this sorted out. To help me better assist you, could you please tell me:

- Are your earbuds pairing correctly via Bluetooth with your Windows device outside the app?
- Does the app show any specific error messages when you try to connect?
- Have you tried any troubleshooting steps so far, like restarting the app or your device?

Once I have these details, I can guide you step-by-step. Meanwhile, here’s a basic approach we can start with:

1. Make sure your earbuds are fully charged and out of the case.
2. On your Windows device, go to Bluetooth settings and delete or "forget" any previous connections related to the earbuds.
3. Restart your Windows device to refresh Bluetooth services.
4. Launch the Earjoy app again (close it fully and reopen it). Make sure no other Bluetooth or audio apps are running.
5. Try to pair the earbuds through the app again.

If the earbuds don’t show up or still won’t connect, you might want to reset the earbuds by holding the touch surface or pressing the reset button on the charging case for about 10 seconds. After resetting, try the connection process once more.

Let me know what you’ve tried and what you see on your screen, and we’ll find a precise solution for you!
