FAQ

• The earbuds are on, but not connecting to my device?
  For the earbuds and your device to establish a connection, you need to put them both in pairing mode. Please follow the instructions in the Pairing section of this manual.

• I’ve connected the earbuds with my smart phone but can’t hear any sound?
  Double-check the volume level on your smart phone and the earbuds. Some smart phones 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 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.

• Wh at’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.

• 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.
