KZ Bluetooth Upgrade Cable C Pin

KZ Bluetooth 5.0 aptX HD Wireless Upgrade Cable – C-Pin Version

Upgrade your compatible KZ or CCA earphones to premium wireless performance with the KZ C-Pin Bluetooth Upgrade Cable. Built around the powerful Qualcomm QCC3034 chipset, this cable delivers significantly improved sound quality, stability, and efficiency compared to standard Bluetooth upgrade cables.

Supporting aptX HD audio transmission with bitrates up to 576kbps, this cable offers clearer detail, wider dynamic range, and sound quality that approaches CD-level playback on supported devices. Combined with Bluetooth 5.0 + EDR, it provides a stable connection, lower latency, and up to 30% lower power consumption compared to older CSR Bluetooth chips.

Designed for everyday use, the cable includes an in-line microphone with cVc noise cancellation, ensuring clear voice calls with effective background noise suppression. An intelligent energy-saving auto-off function disconnects the cable after 10 minutes of inactivity to preserve battery life.
