Both Earbuds Blinking at the Same Time
Both earbuds blinking simultaneously — what synchronized blinking means across brands, including pairing mode, reset, and charging errors.

Quick info
Visual description
Both left and right earbuds blink at exactly the same time in a synchronized pattern. This is distinct from alternating blinks (left then right, or red-blue alternating). When both earbuds blink together — same color, same rhythm — it almost always signals a deliberate mode rather than a random error.
What it means
Synchronized blinking on both earbuds is usually intentional:
Pairing mode: Many true wireless earbuds blink both LEDs together during Bluetooth discovery mode — this is a visual signal that both earbuds are ready to be found as a pair.
Factory reset acknowledgment: After holding the buttons through a factory reset procedure, earbuds blink together to confirm the reset was accepted.
Synchronization loss between earbuds: On some models (especially JLab), both earbuds blink simultaneously every few seconds to indicate they've lost their inter-earbud connection (the left-right sync is broken). This is a known issue requiring re-pairing.
Startup handshake: When earbuds come out of the case, many models blink together as they negotiate which is 'primary' (the one that connects to the phone).
Brand & model variations
The same light pattern can mean different things across manufacturers.
| Brand / Model | What white slow blink means | Recommended action |
|---|---|---|
JLab JBuds Air, Go Air Pro | Both earbuds blinking simultaneously after putting them on but before phone connection = earbuds are searching for each other (inter-earbud sync). Sometimes one earbud loses the other after case removal. Solution: re-pair using the 3-tap or 7-tap reset sequence. | JLab 3-tap reset: quickly tap each earbud 3 times. They reboot and re-sync automatically. |
Anker Soundcore Liberty 4, Life A3i, Space A40 | Both earbuds blink white together after leaving the case = pairing mode. This is normal. Once connected to a device, blinking stops. If still blinking after connecting: secondary connection issue. | Open Bluetooth on phone, tap the Soundcore device to connect. Both earbuds stop blinking once the connection is established. |
Skullcandy Indy, Push Active, Grind | Skullcandy earbuds blink together (typically white) when in pairing mode and blink red together when both are critically low on battery. | White sync blink = connect from Bluetooth. Red sync blink = both earbuds critically low, charge immediately. |
Diagnose your issue
Answer a few questions to narrow down the cause.

Safe next steps
Ordered from least to most involved. Check each step as you go.
Synchronized blinking is almost always pairing mode. Connect from your phone's Bluetooth menu.
If both earbuds blink together in red: charge both immediately, both are critically low.
If sync blink doesn't stop after connecting: place in case, re-open, and re-pair.
JLab earbuds: use the tap reset (3 taps per earbud) if inter-sync is lost.
When to escalate
Stop troubleshooting and contact your ISP or manufacturer if:
- Both earbuds blink indefinitely even after factory reset and won't pair — firmware corruption.
- Synchronized red blinking immediately after charging a full case — battery circuit fault.
