from both earbuds and check that Bluetooth is enabled. If the earbuds still
don’t connect, try resetting them or contact us for assistance.
Q: What to do if one earbud is silent or has low volume?

earbuds and reconnect. If the issue persists, please contact us for
assistance.
Q: What to do if the earbuds are uncomfortable to wear?
