There is an image showing a hexagon pattern. In front of the image, the sentence 'The ultimate material GRAPHENE' is written.
The image shows a brief history of the development of diaphragm materials. From left, a phonograph is shown. Next is a radio, followed by a cassette player, a portable speaker, and a premium speaker. On the right, the LG TONE Free T90S earphone is displayed with a spotlight. Below the product images, icons of diaphragm materials are shown. From left to right: paper, metal, plastic, synthetic fibers, Kevlar, composite materials, ceramic, diamond, and graphene.
Graphene won the Nobel Prize in Physics in 2010. This groundbreaking material is the first truly two-dimensional material ever isolated, consisting of a single layer of carbon atoms arranged in a hexagonal lattice.
Graphene, a one-atom-thick film of carbon, is the thinnest, strongest, and most flexible material ever discovered. Its exceptional properties have opened up new horizons for physics and are being commercialized for various high-tech applications.
The T90S utilizes pure graphene to achieve a perfect balance of natural acoustics in a compact design. Featuring a diaphragm crafted from groundbreaking pure graphene, the T90S meets the true standard of high-end audio. Graphene captures every nuance, delivering clear highs, dense mids, and rich bass. The sound is so natural and balanced that you'll hear details you never noticed before.
