7Hz x Crinacle: Salnotes Dioko Planar IEM

Salnotes is the sub-brand of 7Hz, and Dioko is the model name of their first IEM which has a planar driver like 7Hz’s Timeless. And as you can understand from the headline the new Dioko is another collaboration with Crinacle the tuner and content creator (also the owner of crinacle.com).


The new Salnotes Dioko will be the cheapest Planar IEM on the market at 99$ and will be announced in 3 days.

The newly developed 14.6mm dual-cavity planar diaphragm driver has been modelled and simulated to select the most proper magnetic circuit structure and wire distribution. The diaphragm is made of a high-end substrate imported from Japan and undergoes a precise magnetron sputtering coating and laser etching process, reaching the smallest error that can be achieved by the current industrial technology level.

Salnotes adopted the N55 magnet with the highest performance in the double-sided array type, which is coupled with the magnetic circuit structure.

Matched with the same tempered glass material as found on luxury watches: the shell surface is treated by sapphire coating and an anti-fingerprint process.

The earphone shell is finalized with CNC from aviation-grade aluminium, making the earphone more lightweight. The shell surface has been given the highest level of hard oxidation treatment, making it durable and wear-resistant.

The new Dioko Planar IEM will come with a 4-core Litz structure cable with a mix of OCC copper and silver-plated 0CC copper, with a total of 216 individually coated strands to ensure high-quality sound transmission.
