Billow ADV


When we were trying to improve our Billow, we wanted it to be better at any price. We utilized the original Billow and prototypes of Billow ADV with many reference equipment in studios and decided to use not only our previous compounds but also new elements in the alloy for the thread material of Billow ADV. Now, the new Billow ADV fits better into monitoring use with a new alloy and innovative mixture for its soldering material after many attempts and experiments.


Our new alloy improved conductivity in frequencies that are sensitive to the human ear, which results in the amazing separation in details and its wide soundstage. This means no matter how demanding the track is, Billow ADV can handle and playback the signals perfectly without muddled overlaps and unnecessary interference. This makes the Billow ADV perfect for monitoring and sound mixing. Comparing it with the original Billow, the soundstage of ADV is much wider with an absolutely black background that makes you feel your music has unreachable depth.


The Billow ADV is available in both 4-wire and 8-wire options. The 8-wire option has better treble extension and more bass than the 4-wire option. It depends on your pairing and personal preferences.


Due to the limited availability of cable material, the Billow ADV is limited to 200 sets. Each cable will have its serial number engraved on the warranty card.

4-wire or 8-wire?

The 4-wire option has the advantages of being more economical and lighter in weight.

The 8-wire option has fuller sound, larger soundstage and punchier bass while still feels amazingly soft and easy to use.

Ear Guides

All of our IEM cables have pre-bent earguides by default. There are no wires inside as the ear guide is shaped by ourheat shrink sleeve to eliminate the possibility of oxidation of the metallic memory wires. If you do not want any ear guide, please contact us.


The default length of our IEM cables is about 1.2 meters, while headphone cables are around 1.5 meters. If other lengths are needed, please contact us for alternative arrangements.
