Enjoy true wireless freedom without giving up your favourite IEMs. The KZ AZ09 C-Pin version is designed for earphones that use 0.78mm recessed or flat pins, allowing you to convert compatible KZ and CCA wired earphones into a reliable, low-latency true wireless system in seconds.
Equipped with an advanced Bluetooth 5.2 chipset, the AZ09 offers a more stable connection, longer range, and lower power consumption compared to older Bluetooth versions. AAC audio encoding ensures clean, detailed sound that stays close to the original wired performance.
Each ear hook weighs just around 4.5g and features an ergonomic, skin-friendly resin design that sits comfortably around the ear for long listening sessions. Thanks to dual-host dual-channel transmission, each side connects independently, allowing single-ear use and reduced latency for video and gaming.
