HIFIMAN Topology Diaphragm: The Topology Diaphragm refers to a diaphragm that features a special Nano particle coating applied to its surface. The result is a more natural and detailed sound than what is typically achieved with True Wireless earphones. The idea behind the new Topology Diaphragm was inspired by Dr. Fang Bian's Ph. D. thesis that states, Different Nano materials have differing structures and each of those materials have its own properties. Therefore, by carefully controlling the diaphragm surface structure we can yield different results that are superior in acoustic performance to a degree previously unobtainable.
