Audio-Technica Consumer ATH-LS400iS In-Ear, Quad Armature Driver Headphones with In-Line Mic and Control

Featuring quad balanced armature drivers specially designed for the LS “Live Sound” Series, the ATH-LS400iS in-ear headphones deliver clear, immersive audio with full, powerful bass. Each housing contains one mid-frequency and one high-frequency driver, along with two low-frequency drivers, resulting in incredibly well-balanced sound across the entire frequency range, including a strong, fully realized bass.

The housings are constructed of rigid stainless steel and tough Tritan resin to reduce unwanted resonance while also providing sleek, see-through styling. Specially designed acoustic sound pipes, fashioned from stainless steel and high-durability resin, are encased within the eartip posts, guiding music from the drivers to the listener’s ears with improved high-frequency response. The eartip posts are angled for a comfortable, sound-isolating fit.

The ATH-LS400iS comes with a detachable 1.2 m (3.9') cable with A2DC (Audio Designed Detachable Coaxial) connectors at the headphones for exceptional durability and audio performance. The cable is equipped with an in-line mic and controller for handling phone calls as well as music and video playback on compatible devices. The flexible memory cable loops around the ears for a custom fit that is enhanced by the four sizes (XS, S, M, L) of included eartips.
