One (1) Silicone semi-custom left side ear mold for acoustic tube headsets. Excellent alternative to the standard silicone mushroom tip. This ear mold comfortably stays in place for long periods of time and during aggressive head movement. Sounds are heard clearly and privately. Simply remove your current acoustic tube tip (leaving the plastic elbow in place) and insert the existing acoustic tube elbow into the outside hole of the ear mold earpiece. Place the ear mold pointed stem into the ear canal with the larger lobe upward. Place the half round circle of the ear mold into the ear folds natural grove surrounding the ear canal.
