? ?From 2021 Sep 15th, there are 4 types of cables will be delivered at random. These versions share the same performance with ONLY APPEARENCE DIFFERENCE. Please understand. We suggest upgrading the cable to Tripowin cable to get a sound improment. ? & ?The cavity is made based on large data of cochlea. It’s scientifically molded to fit the ear like a customized in-ear Headphone. Even with vigorous exercise, it will still securely fit in the ear. Comfortable for a long time wearing as well. Because of the special design, it can effectively isolate the noise to 26dB to offer a better experience while enjoying the music. ? ?The PCB board is added to give full play to all the drivers, displaying a smooth, sensible, detailed music experience. The ZS10 Pro overall has dynamic lows and bright resolution. It fully reflects the cohesion of balanced armatures. ? ?The faceplate is made of 304 stainless steel while the cavity is made from imported resin. The two different material not only presents an elegant look and shimmer but also be practical and durable. The detachable gold-plated QDC cable offers fully upgradability and the limit slot protection design greatly avoids the pin from breaking and prolongs the service life of the interface. ? + & ?As an upgraded version of KZ ZS10, the Pro features self-customized balanced armatures which include two 30095 drivers for highs, two 50060 drivers for mids. With this configuration, the sound is transient, dynamic, and bright in all respects. While maintaining the previous performance, the highs of this model is extended beyond 40kHz. It also adopts the second-generation Tesla double magnetic dynamic unit.
