Audio-Technica's first wireless in-ear headphone is taking it one step further with 11mm drivers and an integrated D/A converter and amplifier. These drivers feature a diamond-like carbon coated diaphragm to reduce distortion while machined brass stabilizers and a stainless steel acoustic mesh resistor reduce unwanted resonances while also improving high-frequency response. The headphones use the latest Bluetooth 5.0 standard for wireless connectivity and battery life is rated at up to six hours on a single charge while the carrying case will hold an additional nine hours of battery life.
