Eartronix custom earpieces combines the best technical approach to each component in the efficient transfer of sound from a specific point source to listener's ear.

The receiver bushing in the clear acoustical tube in the earpiece system allows secure and efferent connection to the source, such as a small transceiver or stethoscope. Flexible tubing allows the sound to travel discretely and efficiently to the earpiece. The patented Continuous Flow Adaptor™

The Continuous Flow Adaptor™

• Prevent accidental roll of HF Gain

• Provide smooth frequency response

• consistent acoustic - no surprises

• No interference with sound bore

The patented CFA™ Continuous Flow Adaptor is critical in allowing unimpeded sound transfer into the molded earpiece. It maintains a constant and uniform inside the diameter through the tube to the flange which snaps securely into a seating ring for positive mechanical coupling to the ear mold.

allows unimpeded transfer of the sound into the earpiece. The molded earpiece is formed to fit snugly into the ear canal delivering clean clear sound to the user while blocking out unwanted noise. Where necessary, the earpiece is vented to allow hearing to allow hearing of outside sounds and ambient noise without degrading critical performance or compromising confidential communication

Earmold Materials

POLY-SHEER: A Polymerized vinyl compound for fabrication of custom earpieces. Recognized by the FDA as being chemically inert. Rubber-like texture; will hold shape indefinitely. extremely tough and pliable. will outlast any other Flexible material.

POLY-SHEER II: The newer, softer and more comfortable material that let children and adults enjoy that advantages of pure comfort and protection of one's hearing. Recommendation; For Hypo-Allergenic cases. Seals tight with comfort on severe losses. Highly recommended for children . Ordered by most children clinic.  When used in earplugs there is ANSI Rating Noise Reduction Rating of 28db at 125hz  and 449.9db at 8000hz. (This material is the only one that is certified by ANSI look at Attenuation Data or more data comparison)

POLY-SHEER SS:  The super softest of all the Poly-Sheer  materials. Use this when ears are sensitive to having something in one's ear.
