Astell&Kern is expanding its partnership with headphone manufacturer Beyerdynamic with the release of the new Astell&Kern AKT9iE, a pair of high-end In-Ear Monitors and an update to the company’s AKT8iE model. The AKT9iE has been optimized for use with Astell&Kern digital audio players. The new IEM features a freshly designed acoustic vent port and filter, which Astell&Kern claims can complement the bass and deliver much smoother musical high.
