The Essence of Tesla Technology

Beyerdynamic + Astell&Kern

The AK T8iE Mk 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 Mk 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 Mk 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 Mk, 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 Mk sets a new benchmark.

Internal Structure

New, improved voice-coil

The AK T8iE Mk introduces a brand new voice-coil for a superb listening experience, drawing on all the heritage and audio excellence beyerdynamic has pioneered since 1924.

Keeping the perfectly tuned acoustic signature of the AK T8iE, the new voice-coil increases reliability and lowers distortion to a minimum.

Each voice coil is carefully inspected and adjusted by hand, using a digital microscope camera with 40x magnification.

High-grade transparent silver-plated cables

The AK T8iE MKII is supplied with high-grade silver-plated fiber cables with coaxial construction, a strong upgrade from standard copper cables.

To ensure highest wearing comfort, the cables are skin-friendly and ultra flexible. The transparent sleeve effectively reduces cable noise. All conductors are made from high purity silver/copper alloy (Ag–Cu–alloy) for the purest sound.The cable material is specially fabricated for the new AK T8iE MKII.

For ultimate strength, the cables are reinforced with high tension aramid fiber cores.

High precision gold-plated MMCX connectors

The high precision MMCX system consists of tolerated, including or such as: plugs, sockets and toothed washers.

Low electrical resistance provides the best audio performance possible. High reliability for daily use.

Great Flexibility

Besides the standard 1.3m cable with the general-purpose 3.5mm plug there is an additional balanced cable for Astell&Kern devices(works with AK70 / AK100 II/ AK120 II/ AK240 / AK300 / AK320 / AK380). It provides a balance output with its specific 2.5 mm 4-pole terminal. A leather case stores the in-ears safely for transport.
