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.

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:
1.
2.
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

The sound isn’t very clear or the caller can’t hear my voice clearly
Adjust the volume on your smartphone and the earbuds. Try moving closer to your
smartphone to rule out the possibility of interference or wireless range-related
issues.
What’s the wireless range of the earbuds?
The maximum range is 10m (33ft). However, the actual range depends on environmental
factors. For optimal performance, keep your device connected within a range of
roughly 4m to 8m and make sure that there are no major obstacles (like reinforced
steel walls) between the earbuds and your device.
- 12 -
I’ve connected the earbuds with my smartphone but can’t hear any sound
Double-check the volume level on your smartphone and the earbuds. Some
smartphones require you to set up the earbuds as an audio output device before
the audio can be transmitted. If you’re using a music player or other device, please
make sure it supports the A2DP profile.

The earbuds won’t turn on
Try charging the earbuds for a while. If the earbuds still won’t power on, please
contact our support team at the email address given in Warranty & Customer
Support.
I put the earbuds back in the charging case, but the earbuds are still connected
The charging case is probably out of power. Try charging it.
