The “Topology Diaphragm” refers to a diaphragm featuring a special Nano particle coating applied to its surface. The result is a more natural and detailed sound than what is typically achieved in True Wireless earphones.
The idea behind the new Topology Diaphragm was inspired by Dr Fang Bian's Ph.D. thesis that "different Nano materials have differing structures and each of those materials have its own properties". Therefore, by carefully controlling the diaphragm surface structure you can yield different results in acoustic performance to a degree previously unobtainable.
The HE-R10D package includes three detachable cables with three different jacks:
Wired: Traditional wired 3.5mm input with 3.5mm to 6.35mm connector
