We are proud to present our Oslo MKIV, a revolutionary Oslo in the already popular heritage. This fourth generation uses a seven-by-seven thread design with seven thin alloy threads forming a small wire while seven of these small wires form a large wire. It is worth mentioning that these seven small wires are made up of two different compositions, in the ratio of three to four. Three of them are purple colored with tuning closer to Oslo MKII while the other four are silver colored with tuning closer to the MKIII. The MKIV is achieving higher than before with more than just the merits from previous generations, but also the new seven-by-seven structural design that has not been available on this product line.

The outer sheath is translucent dark purple in color, giving the cable a beautiful purple shade while the purple and silver mix inside are providing a jewelry appearance. Naturally, the outer isolating sheath is using our newest technology for a minimum tangling experience and maximum comfort. As you can see from the pictures, our new golden metallic parts pair perfectly with the purple shade, providing a luxurious look for the Oslo MKIV.

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.
