With the 8mm driver, unique acoustic structure, and industry-leading noise cancellation, the AZ60M2 offers a clear sound advantage. Never miss a beat: thanks to the comfortable design, seamless switching between different devices, and excellent sound quality. The Dual Hybrid Active Noise Cancelling technology combines a digital software filter and a feedforward microphone to suppress external sounds while a feedback microphone works with an analog hardware filter to reduce sounds inside the in-ear headphones. The AZ60M2 now supports multipoint connections with up to three Bluetooth devices simultaneously for seamless switching between sources.
