Wear the ZVOX AV52 Bluetooth headphones for important work calls, thanks to the noise-canceling microphone. In fact, this microphone, which is placed in the right ear cup, allows you to make hands-free phone calls from your phone. With improved noise-canceling technology, the AV52 headphones reduce ambient noise during videoconferences. They also boast AccuVoice technology for improved voice clarity. And, when you switch to the Noise Canceling mode, they reduce distracting sounds while providing a subtle boost to voices. Therefore, you'll hear every word clearly—even in poorly recorded tracks. Moreover, they feature both a Bluetooth and cord connection for versatility. If you opt for the wireless connection, the rechargeable battery system lasts for 24 hours or more. Finally, these headphones are available in 4 stunning colors: white, black, blue, and rose.
