High-MFD structure to improve the sensitivity and tonal quality
The magnetic flux density strengthened by an additional front magnet to achieve increased sensitivity about 4dB.The transient response has been also improved to deliver crisp sound quality.

  • New driver unit provide a precise control. Asa a result, the sound pressure level in low frequency range incresed.
  • The Bass port structure implemented, that increase the energy of the low frequency and optimize the operation of the diaphragm to convey the solid bass sound.
  • Newly designed Deep Mount earpiece. Its' unique shape provide tight fit to the ear canals providing a rich bass reproduction.
  • Mounting position of the earpieces can be adjusted in two stages to achieve a more accurate musical reproduction without missing bass by optimizing their position. Furthermore, while increasing the sound insulation by the secure fit to their ears, they reduce stress on the ears. It is also recommended to use under the noisy environment such as commuting.
  • A nylon braid cable jacket, 2.0mm diameter, used for both the fine texture and functionality.
