A sheath may be folded inside-out to cover a core-form and form an in-ear device therewith. A settable compound is injected between the spacing formed between core-from and sheath to allow in-situ fitting. The sheath is of variable thickness, having lower thickness portions and augmented thickness portions to direct flow and settling of settable compound during in-situ fitting.
