About this product

  • -[Amazing performance] -A hybrid type canal type earphone with BA (balanced armature type driver) and DD (dynamic type driver). -The earpiece with a high fit reduces external noise. -The characteristics of the dynamic type driver in charge of the low range and the balanced armature type driver in charge of the mid to high range are fully utilized. The combination of excellent resolution and separation and the strength of the bass is unique to the hybrid type. The hi-hats and crash cymbals you hear with these earphones are especially excellent. -It is a high cost performance that can definitely be recommended. There is no earphone in the same price range of consumer electronics retailers that can match this ZST. The sound quality is as good as that of earphones made by famous Japanese manufacturers, which have many times the price difference.
  • -[Aging will bring out the original performance] -Aging for 100 to 200 hours will evolve the sound quality to a completely different level from when it was first purchased. The range is widened, and the bass and treble are extended well. The balance of the band is flat, and the sense of localization and distance of vocals is wonderful. The sound field will be wider and more realistic.
  • -For comparison, the same hybrid high-resolution canal type earphones re-cabled to the genuine cable that is usually used in the main have the impression that ZST has a clearer mid-range and high-range and sound field.
  • -[If you use the KZ ZST upgrade cable (sold separately) …]-Compared to the attached cable, the outline of the sound will be clearer and you will be able to hear it clearly. The cable is soft, easy to handle, carefully processed, and has a beautiful design.
