With the ATH-ANC100BT QuietPoint Wireless In-Ear Noise-Canceling Headphones, Audio-Technica has designed a pair of headphones that are meant to comfortably deliver clear audio without any distracting ambient noise. Audio-Technica employs Bluetooth technology to wirelessly stream your favorite audio from a mobile device, such as a smartphone or tablet, and adds active noise-canceling technology to filter out ambient sounds. This makes them ideal for noisy environments like public transit or a busy office. When paired with a smartphone, you can use the built-in microphone for hands-free calling.

The in-ear design offers a lightweight and convenient option when on-the-go, and with up to 10 hours of battery life, the ATH-ANC100BT headphones sport features to help make your listening experience comfortable over extended periods. First, Audio-Technica enclosed the 12mm drives in a compact housing to reduce size, and includes four sizes of silicone eartips, plus a pair of medium-size Comply foam eartips to help give you as custom of a fit as possible.
