美國韋斯頓(Westone)
美國Westone公司是一家專業研發耳用設備的廠商，擁有超過30年的聲學設備研究經驗，一向在專業領域應用廣泛，直至近年才推廣到民用市場，一般音樂愛好者終于可以以大眾化的價格嘗試Westone耳塞的音質及廣闊的音場。和Etymotio（音特美）ER4、ER6、ER6i。Shure（舒爾）E5、E3等耳機一樣。都是采用壓電式單元，但是Westone卻擁有全球第一創造的最先進的2路分音及3路分音技術。與一般動圈耳機不同，壓電式的發音單元可以做的很小，因此可以將2個甚至3個單元放入沒邊聲道內，分別負責高、低音及音場處理。音效能與高級喇叭系統相媲美。另外，Westone耳塞的隔音能力亦超乎想象，高達25dB,在任何嘈雜的環境都可以靜心聆聽音樂。所需音量只及普通耳機的一半。無須將音量調高至損害聽覺的危險水平用以覆蓋外界噪音，最大限度降低耳朵的負荷。

English Information
Westone Laboratories Inc. was established in 1959 in the kitchen of the Morgan family log cabin. The business was based upon three simple concepts; absolute quality, friendly, efficient service and the Golden Rule. A lot has changed since then. Westone has grown to become the world's largest manufacturer of custom made products for the ear. However, our commitment to absolute quality has remained unchanged. The installation of state of the art manufacturing equipment and the use of techniques proprietary to Westone has allowed us to bring innovative and unique products to the hearing healthcare field. Our belief in friendly and efficient service, evidenced by our technical support department and customer service staff is unparalleled by any other earmold manufacturer. And our unshakable reliance on the Golden Rule has allowed Westone to remain a leader in the Oto-plastic industry.

Westone's well deserved reputation for quality, and our willingness to take on even the most demanding challenges, has allowed us to refine our line of custom earmold designs for the hearing impaired as well as provide a full range of hearing protection and communication products. In addition to quality custom made ear products for the hearing impaired, industry, musicians, and recreation, Westone also has a complete line of products for the hearing healthcare professional.
