Voicebuds and the charging case use LED lights to communicate status.
Case battery level
When the lid is opened or closed, the LED on the case briefly turns on to show battery level:
| LED colour | Case battery level |
|---|---|
| White | Over 50% |
| Yellow | Under 50% |
| Red (blinking) | Under 10% — charge soon |
Pairing mode
The case LED slowly pulses white when Voicebuds are in pairing mode and ready to connect. To enter pairing mode: place both buds in the case (lid open) and hold the pairing button for 3 seconds.
Factory reset confirmation
After a successful factory reset, the case LED blinks red 3 times to confirm the reset is complete.
Checking battery in the app
For earbud battery levels, open Voicebuds settings in the Subtle app — it shows left and right levels in 10% steps. The case's charge is shown only by its LED.
Unexpected LED behaviour?
If a pattern appears unexpectedly (constant red, no lights, rapid flashing), place the buds back in the case, close the lid for 10 seconds, then reopen. If the issue persists, contact support at support.subtle.co.
