7Hz

7Hz is a Chinese in-ear brand best known here for the Zero 2 x Crinacle set and the G1. Like several Chi-Fi houses, it does not publish a single clean founding-year story we are willing to reprint as fact.

Nyvrix stocks those two live models. That is the 7Hz range in this shop today.

About the brand

Zero, then Zero 2

7Hz became widely known on the Zero - a cheap single-dynamic IEM with a surprisingly even treble for the money. Zero 2 x Crinacle is the collaboration revision we actually sell. G1 is a separate live SKU, not a colourway of Zero 2.

7Hz at Nyvrix

Two active products. If a new 7Hz lands in stock it will appear on this grid automatically because the collection is vendor-smart. We will not advertise models we do not hold.

Key terms, explained
Zero 2 x Crinacle
The 7Hz / Crinacle collaboration IEM in this shop. A revision of the original Zero, not a flagship.
G1
The other live 7Hz IEM here. Different SKU from Zero 2.
Single dynamic
One moving-coil driver. Both current 7Hz sets in this shop follow that idea unless a spec row says otherwise.
Crinacle collab
A tuning done with the reviewer's input. It does not mean Crinacle manufactures the shell.
Chi-Fi
Chinese enthusiast audio. 7Hz sits in that category next to Truthear and Tangzu, with a more technical than warm reputation on Zero 2.
Detachable cable
Check the product spec. Do not assume every 7Hz shell uses the same pin.
FAQ
Where can I buy 7Hz in Egypt?

Nyvrix stocks 7Hz locally at nyvrix.com. The live product grid on this page is the accurate list of what is in stock. Every unit sold here is genuine, checked on arrival, and covered for 14 days against product defects. Ships in 48h - weekends may vary. Cash on delivery in Egyptian pounds.

Are the 7Hz products at Nyvrix genuine?

Yes. Nyvrix sources 7Hz from the brand or from verified distributors and checks serials on arrival. Grey-market listings on general marketplaces are a different channel - the units on this page are the ones we stand behind.

How fast does Nyvrix ship, and can I pay cash on delivery?

Ships in 48h - weekends may vary. Cash on delivery is available across Egypt, priced in Egyptian pounds. Advice before you order is available in Arabic and English.

What warranty do I get on 7Hz?

14-day cover against product defects from Nyvrix, handled in Egypt. Keep the order confirmation; that is what we use to process a claim.

Which 7Hz products does Nyvrix actually stock?

Zero 2 x Crinacle and G1 when live. The grid above is generated from the live vendor field, so it updates when a model is added or sold through. Draft or unpublished listings never appear here.

Do you sell 7Hz bundles on this page?

No. This page lists solo 7Hz products only. Mix-and-match store bundles, if any, live on the Bundles collection and are not mixed into the brand grid.

Is Zero 2 a Truthear ZERO?

No. Truthear ZERO:RED / BLUE 2 are a different brand. 7Hz Zero 2 is its own IEM. The word Zero is not a shared platform.

Should I buy 7Hz or Truthear as a first technical IEM?

Both are valid. Zero 2 is usually the cheaper 7Hz option; Truthear Gate or ZERO:BLUE 2 is the Truthear equivalent conversation. Listen to the descriptions, then pick one - do not stack both hoping they add.
