Acoustic sound signature of AK T9iE
Our target is to make the 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.
Internal Structure
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 creates a unique harmony. No more sharp highs or too much bass: bring perfect balance to your music with this unique cable.
