Remove the soft, protective, outer covering.

Use a heat gun (or a hair-dryer) to heat the main unit of the Plantronics Voyager Legend. This will loosen the adhesive that bonds the covering to the housing.

Use the pointed end of a small, metal spudger to begin separating the covering from the housing.

Use the rounded, dull end of the spudger to gently detach the rest of the covering.

It may be necessary to reheat the unit to keep the adhesive soft enough to remove the covering without damaging it.
