Maintenance & Pro-Tips

Goal	Solution
Crystal Clear Calls	The ENC works best when the stems are pointed toward your mouth. If you are in a very noisy area, ensure the earbuds are not covered by hair or a hat.
Resetting the Sync	If only one earbud works: "Forget" the device from your phone. Take both buds out, tap both touch zones 5 times simultaneously, put them back in the case, and close the lid for 10 seconds.
Cleaning for Longevity	Sweat can cause a film to form over the charging pins. Every two weeks, wipe the gold contacts on the buds with a dry cloth to ensure the case can always charge them.
