(News) Release of "NICEHCK lofty" IEM with pure beryllium




The obsolescence of audio technology may be faster than we think. As was the case with graphene diaphragm, planar drive type, and electrostatic type, it seems that new materials are first introduced in high-end earphones, but then they are introduced in cheaper models.


Until now, beryllium-coated diaphragms have been used in some inexpensive models costing less than $50, but pure beryllium diaphragms have rarely been used in models other than those in the $1,000 class.


NICEHCK has now released its flagship model "NICEHCK lofty" equipped with a pure beryllium diaphragm. The price is under $300.


It is now available at HiFiGO and Aliexpress.

Neutral sound

If the official frequency response below is correct, the sound seems to be rather neutral and interesting.


NICEHCK lofty evaluation expectations

This is the expected evaluation value based on the frequency characteristics above and analyzed by the evaluation criteria of this blog. It seems that the sound is better balanced than KBEAR Believe, which was talked about for using the same pure beryllium diaphragm, and is suitable for audiophiles. The sound seems to be midrange oriented.


  • Original fidelity of low frequency range: S+
  • Original sound fidelity of midrange: S-
  • Original sound fidelity of high frequency range: B-
  • Presence of low frequency range: B+
  • Presence of midrange: B
  • Presence of high frequency range: C
  • Overall fidelity of the original sound: A






NiceHCK's new product looks pretty good to me. At least based on the frequency response of the official announcement, there is a high possibility that we can hear a well-balanced sound with pure beryllium diaphragm. In terms of sound, I think it will be a rival of DUNU LUNA rather than a rival of final A8000.
