LEDs flash blue
Jabra LEDs flash blue: pairing the Elite 4 earbuds
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
The LEDs of your Jabra Elite 4 flash blue, which is pairing mode, but the phone will not pair or only one earbud plays. Jabra asks you to pair both earbuds, pick the entry with the headphone icon and repeat the steps or try another Bluetooth device.
Safety first
Stop and check this first
- Before resetting the earbuds, say that Jabra erases the list of paired devices and the settings, and that the old entry must be removed from the phone Bluetooth menu.
- To charge the case, the Jabra manual recommends a supply of 5 V with a 0.25 V tolerance and a maximum current below 2 A, and advises against higher voltages.
Safe checks you can perform
- Power on the earbuds and enter pairing mode
- Pick the entry with the headphone icon and enter 0000 if asked for a PIN
- Pair both earbuds even if you will only use one
- Wake the earbuds if they dropped into sleep mode
Leave these tasks to a qualified professional
- Do not attempt this professional task: Update the firmware with the Jabra Sound+ app after pairing
- Do not attempt this professional task: Pair both earbuds with the customer phone step by step
- Do not attempt this professional task: Reset both earbuds and repeat the test with another device

Power on the earbuds and enter pairing mode
- Who:
- you, with the phone Bluetooth on and the technician watching.
- How:
- take both earbuds out of the case or press the left and right buttons: the LEDs of both turn green. Then press and hold those two buttons together for 3 seconds until the earbud LED flashes blue.
- Result that matters:
- put the earbuds in the state Jabra calls ready to pair.
- If the LEDs flash blue:
- the earbuds should now appear in the Bluetooth menu.
- If the LEDs do not go from green to blue:
- release and repeat the 3 second press.
- Evidence to keep:
- short video of the change from green to flashing blue.

Pick the entry with the headphone icon and enter 0000 if asked for a PIN
- Who:

- Result that matters:
- finish pairing with the right entry.
- If the phone confirms the connection and sound plays from the earbuds:
- paired.

Pair both earbuds even if you will only use one
- Who:
- you, with both earbuds and the case.
- How:
- pair both earbuds with the phone first. When done, leave the one you will not use in the case: the manual explains that this activates mono earbud mode, with its own controls on the button of the earbud still in your ear.
- Result that matters:
- check that single-earbud use works after a complete pairing.
- If the chosen earbud plays on its own and the other stays in the case:
- mono mode is correct.
- If the single earbud plays nothing:
- put both in your ears and repeat the full pairing.
- Evidence to keep:
- which earbud was left in the case and whether the other plays audio.

Wake the earbuds if they dropped into sleep mode
- Who:
- you, with the earbuds out of your ears and out of the case.
- How:
- press the left and right buttons to power them on, or put them in the charging case and take them out again. After 15 minutes out of range or 30 minutes idle, the manual says they switch off by themselves.
- Result that matters:
- tell an automatic power-off apart from a real pairing fault.
- If the LEDs turn green and the phone reconnects to the last device by itself:
- it was not a fault.
- If it does not reconnect although the phone is on and close:
- try another Bluetooth device.
- Evidence to keep:
- approximate time of the last connection and the LED colour when powering on.

What it means
In the Jabra FAQ on pairing the Jabra Elite 4 and in its user manual, LEDs flashing blue after holding the left and right buttons for 3 seconds mean pairing mode. If pairing does not finish, Jabra says to repeat the steps or try another device. Other models may differ, and this pattern alone never proves an earbud is faulty.
