KZ ZS10 Pro, Linsoul 4BA+1DD 5 Driver in-Ear HiFi Metal Earphones with Stainless Steel Faceplate, 2 Pin Detachable Cable (Without Mic, Glare Blue)

  • Upgraded 4BA+1DD Hybrid Earphones&Magnetic Dynamic Unit. As an upgraded version of KZ ZS10, the Pro features self-customized balanced armatures which includes two 30095 drivers for high frequency, two 50060 drivers for mid frequency. With this configuration, the sound is transient, dynamic and bright in all respects. While maintaining the previous performance, the high frequency of this model is extended to beyond 40kHz. It also adopts the second generation Tesla double magnetic dynamic unit.
