Technical features: adopt 8 balanced armature, 4-way crossover , 4 3D printed sound tubes, completely 3D printed earphones.

Sound features: a nearly 23mm labyrinth tube makes the lower frequencies more resilient, deeper and more quality.

Medium frequency female voice is sweet but not bored. High frequency ductility is also very good, through the addition of ultra-high frequency makes the whole band sound very plump.

Full 3D printing

Through a 3d-printed sound tube, ACME8 has a large low-frequency gain, low-frequency diving depth, good focusing power, and build a good low-frequency atmosphere. In the middle frequency, reflects the mellow male voice, masculine without losing details. High frequency transparent and more amazing, the level of sound more distinct, overall quality is high.

Precision beauty beyond imagination

1/40 millimeter thick precision, as low as 0.3mm inner diameter sound tube, as low as 0.1mm level features make customized tunings of the sound tube a reality

A milestone for high-end earphones

Supported by ultra-precision 3D printers, realized the exquisite structure which traditional craft could not imagine.

Pioneering tube solutions

With the fully digitized shell and pipe parameters, zero error can be achieved.

Nearly a hundred tuning experiments of different tubes have been carried out to continuously optimize and improve tubes of different frequency bands, so that each band has its unique characteristics to adapt to the sound transmission characteristics of this band.

Unique suppression phase interference technology

Under the length, thickness, curvature, and digital tube, it is possible to calculate the phase delay of the shell. The unique catheter phase technique will minimize the hazard caused by the most difficult phase interference in multi-unit headphones.

Since the development of high-end balanced armature earphones, the two major means of tuning, driver and frequency division have developed to the bottleneck. As an important means of tuning, tube tuning is increasingly appearing in ultimate products. Due to the limited production process, tube tuning has not been effectively applied. The ACME series is designed to provide a template for a controlled digital tuning that allows customers to see the future of headphones growing trend now.

ACME series custom tuning

We can customize the exclusive earphone tuning scheme for you through the one-to–one customization service with the tuning engineer.

Excellent 3D printing technology

Different from the common 3D printing shell earphones, the full-cavity 3D printing technology improves the device precision requirements by several levels.

Expensive equipment and printing time cost, doomed to the full-cavity 3D printing technology temporarily appear in high-end ultimate earphones.

In 3D printing process, the color of resin material has a great influence on the printing accuracy. After many experiments, ACME series custom earphone shell color is limited to black, but through the combination of traditional process, can still achieve different panel process
