Frequency response exceeds 8 kHz, improving voice clarity by over 30%. ➋ Surprisingly compact. The unit volume is only one-third that of dynamic types, making it lighter and more comfortable to wear. ➌ Achieves excellent energy efficiency (impedance 100Ω or higher vs. dynamic type 16-32Ω), reducing power consumption by approximately 40% at the same volume. ➍ Superior environmental resistance. Blocks electromagnetic interference with magnetic shielding of 80dB or more. Stable sound quality in any environment. ➎ Long-life design. No aging of the diaphragm, maintaining clear sound for a long time (dynamic type lifespan: approx. 3 years).
