Using this Countryman adjustable earset earclip is easy. First, make sure your Countryman earset microphone is the right type that this earclip is compatible with. Then, attach the earclip to your ear. You can adjust it to fit your ear comfortably. You can wear it all day long without much discomfort. When using it, be careful not to pull it too hard as it may damage the earclip or the cable hooks. To maintain it, keep it in a dry and clean place. If it gets dirty, you can gently wipe it with a soft cloth. Remember, the earset is not included in the package, so you'll need to use your own Countryman earset with it.
