Hidizs MP145 Planar HiFi IEMs Limited Golden Titanium Edition

Titanium is a widely occurring metal in nature, known for its remarkable chemical stability, high-temperature resistance, low-temperature tolerance, resistance to strong acids and bases, and a unique combination of high strength and low density. It is commonly used in the construction of rockets and spacecraft, earning it the nickname 'space metal.' Titanium exhibits paramagnetism and boasts extremely low electrical and thermal conductivity. However, it is challenging to process and comes at a high cost, making it an ideal material for high-end audio equipment casings.

The Globally Limited Golden Titanium is made of titanium. It is also match and turned  base on the H-2019 standard curve. So the sound performance of Titanium Edition is stabilized and clearer than the aluminum alloy edition. And the Titanium materiel is more expensive than the other materials of the IEMs.Save the Whales, Save the World!

Through a close partnership with WDC (Whale & Dolphin Conservation), the Hidizs team drew inspiration from whales' biological features and aesthetics to create the unique and artistically pleasing in-ear monitors, the MP145.
