Hi alpesh66,
We'd love to see if we can help. So what the light you're seeing is indicating is that your Beats X need to charge. If you've left them to charge, and the light is still blinking, you may try using another charging cable to see if the issue is related to that, or the Beats X.
"To charge, plug your earphones into a power source using the included Lightning cable. Your earphones provide up to 8 hours of playback from a full charge, and up to 2 hours of playback from 5-minute charge.
When your earphones are turned on and set up, the LED indicator light on the power button shows how much listening time is left:
- White: Up to 8 hours left
- Red: Less than an hour left
- Blinking red: Needs to charge"

What you're seeing may also indicate that your Beats X need service. You can find out your service options and estimated pricing by visiting the below link.
