Astell & Kern calls its new flagship earbuds "groundbreaking" and utilizes unipolar micro-planar magnetic drivers and a titanium housing that's handcrafted in Japan. However, Astell & Kern is asking a hefty price for these ultra-high-end headphones.

The brand-new Astell & Kern Luna are being marketed as "groundbreaking" earbuds. This claim is mostly justified by the unipolar planar 13mm drivers, which have been specially developed for the Luna and are housed in a robust aluminum frame.

This driver aims to offer exceptionally fast response times, natural resonance characteristics and first-class resolution in order to accurately reproduce even the tiniest acoustic details. Astell & Kern’s official spec sheet specifies a frequency range of 20Hz to 30kHz, an impedance of 5 ohms and a sensitivity of 105 dB/mW.

The included cable has a 4.4mm connector and combines oxygen-free copper with a silver coating to deliver the best possible sound. If damaged, the cable can be replaced, and the earbuds are also compatible with third-party cables that have a 2-pin connector. These headphones are made in Japan, their titanium housing is supposedly even handcrafted. The shape of the housing was inspired by the “gentle shape of the moon”, which also explains the product name of these IEMs.

Price and availability

The Astell & Kern Luna flagship headphones are now available for $2,700 at certain online retailers, such as Bloom Audio. In addition to the earbuds themselves and the corresponding cable, Astell & Kern includes seven pairs of ear tips made from three different materials, as well as an Alcantara carrying case.
