KZ AZ20: A Perfect Fusion of Technology, Comfort and Exceptional Sound

Have you ever been frustrated by the poor sound quality of your wireless earphones? It's not always your earphones' fault; often, it's about the Bluetooth chip they use. If you desire the convenience of wireless headphones without compromising on sound quality, the KZ AZ20, equipped with a high-end QCC5171 chip, is your solution.


KZ AZ20 promises to deliver the purest and most immersive listening experience. In the audio realm, a higher sampling frequency and bitrate translate into richer, more natural sound reproduction. The 24bit 384kHz capability of the QCC5171 chip pushes the boundaries of wireless audio technology, recreating the most intricate details of your music.


Boasting the QCC5171 chip, currently the pinnacle of Bluetooth technology, KZ AZ20 isn't about false promises. This ultra-high signal-to-noise ratio chip effortlessly covers the frequency response curve of Hi-Fi earphones, providing a clean background sound even under high power output, and offering an unrivaled auditory feast.


In terms of sound quality, call performance, overall performance and power consumption, KZ AZ20 stands at the apex. Using Qualcomm's aptX Adaptive technology, the AZ20 supports high-definition audio transmission at 24-bit 48kHz and 24-bit 96kHz, and CD-quality 16-bit 44.1kHz lossless audio through aptX Lossless. The QCC5171, combined with the advanced Qualcomm technologies, delivers a wireless audio quality that rivals wired audio, faster Bluetooth connections, improved range and stability, and enhanced resistance to interference.


Enjoy the freedom of music without the hassle of tangled wires. With KZ AZ20, a simple plug and unplug quickly turns your wired earphones into professional wireless ones.


KZ AZ20 boasts an ergonomic design that is based on years of extensive research on human ear contours. The ear hook, made from skin-friendly silicone gel, is pre-molded for a perfect fit. This ensures a secure and comfortable experience even during extended use. Compared to other Bluetooth ear hook products, the AZ20's ear hook volume is reduced by 30%, making it more lightweight and comfortable.


With three performance modes: Gaming Mode, Balanced Mode, and Bass Boost Mode, KZ AZ20 allows you to customize your audio experience based on your preferences and the type of content you are listening to.


The KZ AZ20 provides approximately 6 hours of playback on a single full charge. With the charging case, the total battery life extends to about 54 hours, allowing you to enjoy your music anytime, anywhere, without worrying about frequent charging.


KZ believes in environmental protection and doesn't inflate prices in its name. AZ20 comes in simple and practical packaging, focusing on the performance of the product, not the luxury of the packaging.
