Article ID :
Currently, I can only wear the headset on my right (or left) ear. Can I wear the headset on my other ear?
Yes, you can wear the headset on either ear.
To adjust the headset to be worn on the other ear, remove the earloop by gently pulling up on earloop near the Plantronics name until you hear a snap. To replace, gently snap back onto post.
