Why customers choose Nexoltic

Meet the EZ EAR KZ ZST Bluetooth IEM Module, a modular wireless upgrade designed to fit a wide range of in-ear monitors. By choosing either the B-pin 0.78mm or the C-pin 0.75mm socket, you can tailor the adapter to compatible models like KZ ZST, ZST-X, AS10, ZS10 Pro, and several Moondrop or CCA variants. This flexibility helps you refresh existing IEMs without changing your whole setup.

Fast, stable wireless with rich detail

The 5.4 Bluetooth module provides faster transmission and a more stable connection, which can make on-the-go listening feel smoother. AAC encoding support and a robust chip guard work behind the scenes to maintain clarity as you move between tracks, movies, and calls.

  • Low-latency dual-channel transmission helps keep audio in sync during video or gaming.
  • Dual-host design lets you use the earhooks on their own for different wearing preferences.

Long listening sessions, wherever you are

A single charge powers about 6 hours of use per earhook. The 800mAh case recharges the buds up to seven times, delivering up to roughly 42 hours of combined playback between charges. A compact case makes it easy to take on trips or commutes.

  • Lightweight design at around 4.5g per earhook reduces pressure for all-day wear.
  • One multi-function button handles calls, play/pause, and track switching, simplifying control while active.

Comfort, fit, and quick setup

Weighing only a few grams per side, the earhooks sit comfortably in your ears without pinching. The quick-switch pin options support a broad range of IEM connectors, helping you swap between favorites with minimal effort.

Whether you are traveling, gaming, or listening at home, the EZ EAR KZ ZST Bluetooth Module is designed to expand your options without adding bulk. It is a flexible solution for users who value sound quality, reliability, and portability, presented as possibilities rather than guarantees. Your experience may vary based on device compatibility and environmental factors.
