Xiaomi Piston III Youth Edition

20-20000 Hz, 98 dB, 32 Ohm <b>Aerospace-grade metal diaphragm with a patented “sandwich” design</b>
Excellent sound quality begins with the diaphragm, which is embedded at the heart of any headphone. In order to deliver a superior sound in the mid and bass ranges, we sandwiched an aerospace-grade metal composite layer inbetween two PET layers. This preserves the outstanding treble responses of metal, while improving richness in the lower ranges thanks to the incredible flexibility of PET. This breakthrough design has revolutionized Mi In-Ear Headphones, providing balanced output and superior definition across the entire frequency range.

<b>Optimized front cavity for improved treble performance</b>
The 3rd gen balanced damping improves airflow to deliver proportioned outflows for the front and back chambers. Combined with built-in damping material, Mi In-Ear Headphones produce vivid stereo effects and a transparent, wall-balanced sound. The metal composite diaphragm speakers are allowed to operate naturally to deliver a high-fidelity experience. In addition, a separate output channel and output hole in the front cavity provide better balance and treble performance.
