Push-On Ear Tips:

Are your current ear tips black?

If so, simply pull off the old ones and pop on your replacement ear tips.

Screw-On Ear Tips:

Are your current ear tips gray? Can you see threads where your eartip was?

If so, your Ultrascope uses screw-on ear tips.

If you are having trouble keeping your ear tips screwed-on, put a drop of superglue on the threads before screwing on your replacement. Let dry 15 minutes before using.

If the inner metal piece of your eartip has remained glued to the tip of the binaural, take one of your spare eartips, pinch and pull the rubber off the metal piece, and push the new eartip over the metal piece.
