HIFIMAN Topology Diaphragm
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.
Elegance Outside, Strength Inside
The exterior of the headband is covered by high-quality leather, giving it a soft and elegant appearance. Inside, there is high-grade memory foam, selected to achieve the most comfortable fit and elasticity. The headband skeleton itself is made of solid steel.
The structure is both lightweight and strong, robust yet delicate, and designed to convey detail and musicality that is unmatched in the market.
Large Ear Cups for Superior Acoustics
The crimson red ear cups are large, with internal space that helps produce substantial special volume and the necessary breathing room for the powerful driver to sound its best.
Cable Connections – Dual Compatibility Mode
The socket can accommodate both dual-sided unbalanced 3.5mm cable and a single-sided 3.5mm balanced cable (left socket). Bluemini R2R dongle (separate purchase) easily connects to the left socket.
