Getting Started
Charging
Fully charge the charging case before first use. To charge, connect the case to a USB charger or charging port with the included USB-A to C cable (or put the case on a wireless charger). When all four LED battery level indicator lights are solid white, the case is fully charged. Charging takes around 2 hours, and after being fully charged, the case can fully charge the earbuds 5 times. The earbuds should be stored in the case when not in use.
Turning On / Off
| Turn On | Remove both earbuds from the charging case or touch and hold on the touch-sensitive panels on both earbuds for 2 seconds when they are turned off |
| Turn Off | Return both earbuds to the charging case or touch and hold on the touch-sensitive panels on both earbuds for 5 seconds when they are turned on |
Pairing
Starting with the earbuds in the case:
- Take the left and right earbuds out of the case. They will turn on automatically and connect with each other within 5 seconds
- After the earbuds have connected successfully, the LED status indicator on the master earbud will flash white slowly. This indicates the earbuds are ready to pair
- From the list of available devices, find and select “AUKEY EP-T31”
- If a code or PIN is required for pairing, enter “0000”
Regular Use After Pairing
Once the earbuds are successfully paired with your device, they can be switched on and off as follows:
- Take the earbuds out of the charging case and they will turn on and connect with each other automatically
- To power off, put the earbuds back in the charging case and they will begin charging
Using the Left/Right Earbud Only
Starting with the earbuds in the case:
- Take the left/right earbud out
- Turn on the pairing function on the device you want to pair with the earbud
- From the list of available devices, find and select “AUKEY EP-T31”
Low-Latency Mode
For the best experience when watching videos & movies or playing games, the video output on your device and the audio output from earbuds should be in sync. The EP-T31 earbuds feature a Low-Latency Mode to ensure sound output precisely matches video output. Turn it on or off by triple-tapping the touch-sensitive panel on the right earbud while the earbuds are connected. When only playing music or outputting other audio without any video, Low-Latency Mode isn’t needed so it’s recommended to leave it off for best-possible connection quality.
Clearing the Pairing List
Starting with the earbuds in the case:
- Simultaneously touch and hold on the touch-sensitive panels on both earbuds for 10 seconds. The LED status indicators on both earbuds will flash red and white alternately three times and the pairing list will be cleared
- Take the earbuds out of the charging case. They will turn on, connect with each other, and enter pairing mode
Notes
- When you turn on the earbuds, they will automatically reconnect to the last-paired device or enter pairing mode if no paired device is found
- In pairing mode, the earbuds will automatically turn off after 5 minutes if no devices are paired
- If one of the earbuds has no sound output, put both earbuds back in the charging case and take them out again
- The wireless operating range is 10m (33ft). If you exceed this range, the earbuds will disconnect from your paired device. The connection will be re-established if you re-enter the wireless range within 2 minutes
