## Description

The source sound is delivered as it is 
 This is an earphone produced by Reversed Sound Technology which comes to your ears with surprises at the first try-on with the familiar impression that you can get only from those high-end earphones. 
 The RST is a unique proprietary technology that was designed by (1) inverting the diaphragm, (2) facing the voice coil to the correct direction to the eardrum. 
 As a result, RST is to be able to deliver larger sound range. It dares to challenge against those high-end earphones in the market in delivering actual and realistic sounds. 
 
 
Design and Appearance 
 The package comes with 2 different sizes of rubber ear tips. 
 The housing of the earphone was done via Aluminum casting. 
 The flat-wire prevents earphone wires from messing and twisting. 
 
 
Excellent finishing & Completeness 
 Aluminum housing is not only damage-resistant but also enlarges the space for the vibration panel, which results in clear sound with rich resolution. 
 The entire finishing work from the plug to the cable gives good satisfaction and completeness. 
 
 
Microphone and Remote control 
 There are models with microphone and simple remote control. The one touch remote control button was designed to work with the iPhone or iPad. 
 Microphone is placed at the back side of remote control. For the maximized performance and compatibility with iPhone, these models are built with 32Ω impedence.
