The brand new AK T9iE is the third in-ear collaboration product by beyerdynamic and Astell&Kern. Specially tuned for Astell&Kern portable music players, the AK T9iE has a neutral sound signature with soft treble, linear midrange and slenderly elevated bass.

It uses beyerdynamic's patented high-efficiency Tesla Technology and is made by hand in Germany, to meet the highest expectations. 

The goal is to make the sound more natural, when playing back hi-res audio with. The newly designed acoustic vent port offers improved bass response and enhanced treble softness by specially engineered two-layer acoustic filter with integral earwax protection. The new acoustic design vent port has a slightly enlarged vent hole in the middle of the cover plate, allowing a deep bass that is extremely well controlled.

A two-layer acoustic filter is utilized in the sound outlet and serves two purposes - protection from earwax and an acoustic filter element which produces very pure and neutral treble.

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 creates a unique harmony.
No more sharp highs or too much bass: bring perfect balance to your music with this unique cable.

This is a new ultra-compact IEM optimized with 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 you see different shapes depending on the viewpoint. It also has an ergonomic design that makes them comfortable to wear for many hours of music listening.
