Upgraded 4.4MM Replacement Cable for Etymotic Earphones

Raw Material & Design Concept: This cable is a 4-core upgraded cable with Etymotic to 2.5MM/3.5MM/4.4MM plug models. The cable is made of high-purity oxygen-free copper, providing a sharper bass response through higher linearity and resolution. The design features a gold-plated plug, a pure copper separator, and an ear-mounted hook design.

Upgrade & Improvement in Sound Quality: By using the 4-core configuration with 30 pieces per core, the transmission loss is minimized to the maximum, and the original ability of the cable is displayed. This results in the sound quality being improved to be more realistic, brighter, and less distorted, allowing for a new stage of music sound to be explored.

Instructions for Use: The cable adopts special technology, making it look sophisticated yet elegant and neat. It is mainly divided into two models, one with a wire and one without. The wire-style ear hooks can be safely bent and fixed to the best angle for comfortable wear. The wire-free models are overall soft and easy to store without any tangles. Whether you are quietly enjoying music or doing sports, you can wear this cable with ease.

Wide Application: This cable is suitable for most devices and headphones, even high-end earplugs. It is compatible with Etymotic ER4SR, ER4XR, ER3XR, ER3SE, ER2XR, ER2SE, and LN008099, among others.
