Beyerdynamic + Astell&Kern

Astell&Kern is proud to announce the all-new AK T9iE. The AK T9iE is the third in-ear collaboration product by Beyerdynamic and Astell&Kern. The AK T9iE uses beyerdynamic's patented high-efficiency Tesla Technology and is manufactured by hand in Germany, satisfying the highest standards.

The acoustic sound signature of AK T9iE

Our target is to make them sound more natural, especially when playing back hi-res audio with Astell&Kern Players. The newly designed acoustic vent port allows for improved bass response and enhanced treble softness by specially engineered two-layer acoustic filter with integral earwax protection.

New acoustic vent port

The newly designed acoustic vent port has a slightly enlarged vent hole that is located in the middle of the cover plate which allows for a very deep bass that is extremely well controlled.

Two-layer acoustic filter

A specially engineered two-layer acoustic filter is utilized in the sound outlet, different from the AK T8iE MkⅡ, and serves two purposes - protection from earwax and an acoustic filter element which produces very pure and neutral treble.

4N pure silver and 7N OCC copper hybrid 2.5mm 4-pole cable

The same cable used for AK T5p 2nd Generation has been utilized for AK T9iE. It's made with 4N pure silver with silver plated 7N OCC to deliver the high in this combination, and the 7N OCC to bring the low. This hybrid construction of pure silver, silver OCC, and OCC Litz create a unique harmony. No more sharp highs or too much bass: bring perfect balance to your music with this unique cable.

Design Concept

AK T9iE is a new ultra-compact IEM optimized with both: the technologies of Beyerdynamic and the design identity of Astell&Kern. The design of AK T9iE highlights the "Contrast of Surfaces" and shows the delicacy and details of Astell&Kern with jewel-like carved planes on the exterior housing. The illumination from the PVD coating will reveal different reflections of light so that you see various shapes depending on the viewpoint. It also has an ergonomic design that makes them comfortable to wear for many hours of music listening.
