The AK T8iE MkII succeeds and improves on the AK T8iE, the world's first Tesla in-ear headphone, collaboratively developed by Astell&Kern and beyerdynamic. The new flagship model promises truly outstanding sound and exceptional build quality. 

The AK T8iE MkII has high-grade silver-plated fiber cables with coaxial construction, an upgrade from copper cables. It also introduces a new voice-coil, drawing on all of the audio excellence beyerdynamic has pioneered since 1924. Despite its small size, the AK T8iE MkII allows users to experience an extremely wide frequency range, with crisp bass, well-balanced mids and crystal-clear highs. Like its predecessor, the AK T8iE MkII, is hand-made by highly skilled engineers in Germany. Combining Astell&Kern's philosophy of "providing the original sound" with the expertise of beyerdynamic, the AK T8iE MkII sets a new benchmark.
