The E-A-RLink 3B Insert Eartips in Beige are disposable, single-use foam eartips designed for 3M E-A-RTONE 3A and 5A Insert Earphones, made in a Small, Pediatric Size (1/2 inch height, 9.7mm diameter) for testing younger or smaller-eared patients. This 750-piece case brings the per-tip cost down to roughly $0.52 versus $0.64 in the 100-pack, making it the efficient choice for pediatric audiology practices running frequent hearing tests. Latex-free and made from the same time-tested 3M foam used in Classic Yellow and Beige earplugs, these tips offer the audiometric advantages of direct ear-canal coupling — better noise attenuation, elimination of collapsed canal artifact, and single-use infection control — at a bulk-ready quantity.
