Utilizing eight different microphones, the EAH-AZ60 Noise-Canceling True Wireless In-Ear Headphones from Technics combine premium sound reproduction with extensive noise cancellation, making them an ideal audio solution for nearly any environment. When listening, dual hybrid noise cancellation technology filters out distracting ambient sound, leaving you isolated with your music. Music is made to sound rich and expansive, thanks to Hi-Res Audio Wireless and LDAC codec support. When you need to talk, Technics JustMyVoice technology automatically detects when you speak and only transmits audio when you talk. To further ensure clarity while on hands-free calls, the AZ60 actively filters out ambient noise and wind, while beamforming technology focuses on your voice. Even with all of this technology, the AZ60 in-ear headphones provide up to 7 hours of playback, with another 17 hours available in the included charging case.
