ATH-E40

The proprietary dual phase push-pull driver design of the ATH-E40 professional in-ear monitor headphones provides improved fidelity and efficiency. These headphones deliver powerful bass along with balanced mid and high frequencies to convey the full emotion of the music from the stage to the street.

The ATH-E40 features specially designed housings that provide incredible isolation. The isolation – and the comfort – are enhanced by the four sizes of included silicone eartips (XS/S/M/L), which allow you to create a custom fit. The headphones also come with a detachable 1.6 m (5.2′) cable, with newly developed A2DC (Audio Designed Detachable Coaxial) connectors at the headphones and a 3.5 mm (1/8″) stereo mini-plug output, and a carrying case.

Since 2015, Audio-Technica has used the specially designed A2DC (Audio Designed Detachable Coaxial) connector on all of our in-ear headphones and select over-ear headphones with detachable cables. But why did we develop this connector and what makes it perform better than existing connectors​ in audio applications?
