The ATH-ANC300TW QuietPoint in-ear headphones strike the perfect balance between comfort, convenience, and performance, delivering best-in-class sound quality and noise-cancellation in a compact, truly wireless design. The headphones feature 5.8 mm drivers with DLC (diamond-like carbon) coated diaphragms to deliver exceptional full-range audio reproduction from a Bluetooth wireless transmission. In addition, the headphones are equipped with our digital hybrid noise-cancelling technology to provide the highest degree of QuietPoint ambient noise reduction. Two microphones in each earbud (one in front of the driver and one behind) pick up environmental noise and feed it into the high-precision, digital noise-cancelling processor. The feedback mic is positioned perpendicular to the driver to optimize the space within the sound tube and ensure efficient sound delivery. The ATH-ANC300TW headphones have a built-in mic and multifunction buttons for convenient control of music playback, calls, and a quick hear-through function that lets you hear outside noise, such as conversations and announcements, when desired. The headphones are also compatible with the Audio-Technica Connect app, giving you control of various settings, including three noise-cancelling modes: Airplane, which targets constant low-frequency noise; On-the-Go, which suppresses street noise; and Office/Study, which responds to noise in quiet environments. The headphones are compatible with the high-quality Qualcomm aptX audio and AAC codecs, and with Qualcomm TrueWireless Stereo Plus, a special low-latency function that allows you to stream the latest releases with no audio disruption and a stable connection. These compact, ergonomic earbuds fit naturally in ears of all sizes and come with four sizes of thin, flexible silicone eartips (XS/S/M/L), plus a pair of Comply foam eartips (M), to further customize the fit. The earbuds have an IPX2 water-resistance rating and offer up to 4.5 hours of continuous use on a full charge, with 13.5 hours of additional power available from the charging case. A 30 cm (1.0') USB-A/USB-C charging cable is included to charge the case when needed. Requires a smartphone/device that is compatible with Qualcomm TrueWireless Stereo Plus functionality.
