7Hz x Crinacle Salnotes Dioko Planar IEM Earphones

The 7Hz Salnotes Dioko is a planar IEM built around a newly developed 14.6mm dual-cavity planar diaphragm driver. Its biggest benefit is clarity: each note comes through with detail, in a loose, natural and transparent sound.

The tuning was done together with well-known audio reviewer Crinacle, aiming for a natural and balanced sound that suits both professional and studio use. If you are looking for a 7hz earphone that goes beyond a basic daily driver, this is a strong place to start.

It is a good fit for focused music listening at home, at your desk, or on the move, thanks to a lightweight metal shell and a storage box that keeps everything together.

Key Features

• 14.6mm dual-cavity planar diaphragm driver: The driver's magnetic circuit and wire layout were modeled and simulated to find the best structure. You get clear, detailed sound on every note.
• 7Hz x Crinacle tuning: Based on Crinacle's own idea of a natural, balanced earphone. The result is a sound that is easy to enjoy and suitable for studio-style listening.
• N55 double-sided magnet array: N55 is the highest-performance grade used here, and the double-sided layout maximizes magnetic flux. That helps the planar driver respond with high sensitivity and a transparent sound.
• CNC-machined aviation-grade aluminum shell: The body is durable yet lightweight, and the metal casing helps isolate noise so you can focus on your music. A hard oxidation treatment makes the surface wear-resistant.
• Tempered glass with sapphire coating: The same type of tempered glass used on luxury watches, plus a sapphire coating and anti-fingerprint finish. It stays hard-wearing and keeps a polished look.
• 4-core Litz cable with 216 strands: The cable mixes copper and silver-plated copper, with every strand individually coated. This supports quality signal transmission and a good balance between bass, mids and treble.
• Customized storage box: A large-capacity storage box comes in place of paper packaging. It is practical for carrying and more environmentally friendly.
