Description

KZ AZ09 Pro - an enhanced version of the popular Knowledge Zenith Bluetooth adapter for headphones, featuring the new QCC3040 chip from Qualcomm and support for aptX codec for high-quality audio transmission, increased battery life, and improved CVC noise cancellation during calls. Each KZ AZ09 Pro module weighs only 4.9 grams, easily hiding behind the ears and not interfering with the use of headphones during walks or trips.

Each module has a microphone and a multifunction button, allowing you to control playback, calls, and voice assistant. The left and right KZ AZ09 Pro devices can be used separately. The new Bluetooth 5.2 version achieves increased data transfer speed, stable connection up to 15 meters, and up to 8 hours of music playback. The package includes a plastic case with an 800mAh battery, capable of charging the modules 8-10 times, with charging done through the modern USB Type-C interface.

For the battery life test conducted at the KZ laboratory, the song "Hotel California" was played at 70% volume. In this mode, the KZ AZ09 Pro modules can last approximately 8 hours without interruption. This was made possible thanks to the updated QCC3040 chip with Bluetooth 5.2 support, which improved energy efficiency, speed, stability, and range of connection. The signal remains clear up to 15 meters, and the latency has been reduced to 40 milliseconds compared to 80 milliseconds in the older Bluetooth 5.0 version. The case, measuring 8.7x7.4x3.5 cm, is suitable for most KZ headphone models, and the built-in 800mAh battery allows for approximately 8-10 module charges, extending the autonomy to two days of usage.

The compact dimensions and 4.9-gram weight, combined with a comfortable ergonomic shape, allow for comfortable use with most KZ headphone models, without wires, during walks and even during workouts. The ear hook coverings are made of a pleasant-to-touch hypoallergenic silicone and do not cause discomfort when worn. The adapters completely hide behind the ears, while still offering access to the button, which can be used to pause music playback, play the next track, answer or reject calls, and activate the voice assistant on the smartphone.

The KZ AZ09 Pro modules feature microphones for making calls and using voice assistants. The Pro version supports CVC noise cancellation, eliminating external noise during calls. The LED indicator shows when the device and case need to be charged. When the module's remaining charge is low, the indicator flashes four times every 30 seconds, and when placed on the charger, the case indicator turns red. A green light indicates a 100% charge.
