Comparison Notes

7Hz Salnotes Zero 2 and KZ EDX Pro X solve the same IEM buying question from different hardware starting points. Salnotes Zero 2 uses 10mm Dual-Cavity Dynamic, while EDX Pro X uses Super-Linear Dynamic, so the comparison should start with architecture before moving to price or brand preference.

At least one sensitivity value lacks a voltage/power reference or is unconfirmed. These numbers cannot rank loudness, amplifier needs or sound quality.

7Hz Salnotes Zero 2

Retailer listing: Linsoul · Source checked:

The inspected retailer specification lists the driver and impedance but does not provide sensitivity. An earlier unsupported sensitivity value has been removed.

KZ EDX Pro X

Manufacturer: KZ · Source checked:

The inspected source lists sensitivity in dB without identifying a per-mW or per-volt reference. The displayed value is retained as a quotation, not a normalized comparison.

— means the inspected source does not establish a reliable value.
