AK ZERO1

The AK ZERO1 is an in-ear monitor that combines three driver technologies in each earpiece. A micro rectangular planar dynamic driver handles the treble, two custom balanced armature drivers cover vocals, and a 5.6 mm dynamic driver supplies the bass. The drivers sit in 3D-printed acoustic chambers, and a crossover network shapes the frequency response.

The housing is CNC-machined aluminum with a diagonally cut character line, and the nozzles are slim to suit the ear canal. The earpieces are assembled by hand in Japan. The supplied 4-core cable uses silver-coated oxygen-free copper with aluminum plugs.

The earpieces connect through MMCX sockets. The included cable ends in a 3.5 mm plug, and a 4.4 mm balanced cable is available separately. The set comes with silicone and foam ear tips and a carrying case.
