The KZ AZ09 is a Bluetooth ear hook that turns KZ's wired in-ear monitors into true wireless earphones. You plug the IEMs onto gold-plated pins, pair over Bluetooth with iOS or Android, and lose the cable. Each hook weighs about 4.5 g and uses skin-friendly resin, so long wear stays light. It suits people who already own KZ or other detachable-cable IEMs and want wireless freedom without buying new earbuds. Against dedicated wireless earbuds it wins on reusing your own drivers but adds bulk behind the ear and depends on the fit of the IEMs you attach. Buyers rate it around 3.7 out of 5, with sound and value liked and connection stability and the hook fit drawing complaints.
