$ 999.00

Beyerdynamic + Astell&Kern

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.

New, improved voice-coil

The AK T8iE MkⅡ 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, perfectly fitting components 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.

    I received my T8IE MKII’s last week and recommendations from Jared turned out to be spot on and even better to me. I am currently listening to a pair of SE846’s powered by the AK 300 and was thoroughly pleased with that pairing until the entry of the AK T8IE MKII’s. The sound stage opened up much better with this new pairing using the balanced cabling and the balanced output of the AK 300. The high end frequencies were amazing and sounded realistic and pleasing. There was significant bass presence, electric or stand up bass without being muddy or murky. The response was quick and clear, which is key if you are listening to a Jazz trio or quartet.

    I am amazed that the small size of these can deliver such clear and crisp sound representation. They are light and easy to wear and do not see any issue with wearing these for extended periods of time. I would definitely recommend these to my friends and fellow colleagues.
