The AK T8iE has been developed and designed from scratch to offer a superior in-ear sound experience


Beyerdynamic + Astell&Kern

The first high-end in-ear model with Tesla Technology inside AK T8iE from beyerdynamic in cooperation with Astell&Kern

The AK T8iE has been developed and designed from scratch to offer a superior in-ear sound experience. The finest engineers who developed acoustic reference headphones such as the T1 and AK T5p also designed the AK T8iE, a landmark in the Tesla family. The dynamic moving-coil transducer offers an extreme wide frequency range with crisp bass, well-balanced mids and crystal-clear highs.

Each AK T8iE is handcrafted in Germany by skilled employees, who have long-term experience assembling small electronic components. Every single constituent of the AK T8iE is tested and approved multiple times before leaving the assembly line. This guarantees the highest level of quality and long lasting product durability.

The Tesla Technology inside the AK T8iE stands for a superb listening experience. First emerged in 2009 with the reference headphones the T1 and later the AK T5p, the Tesla in-ear is dramatically miniaturised with the same characteristics of its bigger siblings. An extremely high magnetic flux density within a ring magnet ensures a balanced, undistorted, transparent and neutral sound reproduction.

Sounds like an integrated whole

In comparison to other earphones with Balanced Armature (BA) technology, there is no separate transducer for bass, mid-range or treble tones. This avoids phase problems and the losses of sound quality that results from this. From deep bass to the highest trebles, the AK T8iE sounds like an integrated whole. Additionally, the efficiency of the Tesla transducer is so high that it can easily be matched to a 4-way BA system

Anatomically shaped for a perfect fit

The concha design with the cable running rearwards over the ear has several advantages. The in-ears are easily inserted, and don't fall out because the cable doesn't pull. The oval shaped concha moulds sit very comfortably in the auricle without any pressure. Therefore a variety of ear canals of people from around the world were measured. On top of that five different sizes of anatomically shaped silicone tips and three pairs of Comply (trademark) foam earths ensure the perfect ear for every ear.

Greater Flexibility

All cables are Kevlar reinforced and exceed highest quality demands, steeled for everyday use and mobile application. 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 (AK100 II / AK120 II / AK240 / AK380). It provides a balance output with its specific 2.5mm 4-pole terminal. A leather case stores the in-ears safely for transport. Handmade in Germany
