EarrBond EBT Bi Metal IEM Eartips

EBT Bi Metal Series models:
EarrBOND’s new metal tube earplugs sound intriguing! The “steel-wrapped copper” Bi-Metal tube design is a clever approach. By partially covering the Stainless Steel surface with oxygen-free copper, they maintain the distinct sound characteristics of both metals.

It is a hybrid design with metal tube, memory foam and silicone shell

The series consists with three sizes

-Small
-Asian-fit
-Standard

The Bi Metal tube construction

Oxygen-Free Copper (OFC):
OFC, being a soft metal, enhances performance across the earphone/headphone’s frequency ranges.
It results in improved richness of sound and strengthens the low-frequency rebound sensation.
The use of OFC ensures a warmer, more inviting sound.

Stainless Steel:
Stainless steel, being harder, contributes to a sharper and more solid sound across the entire frequency range.
It effectively reduces sound distortion.
The purified tubing ensures clearer and more accurate high-frequency response, providing clean-lines.

The concept of the Bi-Metal tube design draws inspiration from Hong Kong’s popular traditional drink “Yuanyang Tea” , “Milk tea blends with Coffee.” Just as this drink combines the best of both worlds, the Bi-Metal tube combines OFC and Stainless Steel features. Here are the two models:

1. Half-and-Half Design (C2S2):

This model blends the sound signature of OFC and stainless steel.
The ratio brings clarity, accuracy, warmth, and a strengthened low-frequency rebound sensation.


2. Quarter OFC Design (C1S3):

This design leans more toward stainless steel but retains a hint of the “OFC aftertaste.”
It slightly softens the sharp and solid characteristics from stainless steel.
