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.

Truthear Zero: RED (Crinacle)

Manufacturer: Truthear · Source checked: 2026-09-09

Sensitivity is stated per RMS volt. Preserve any stated test frequency and tolerance; it is not directly comparable with a per-milliwatt figure.

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

Price bands are historical directory categories, not current offers. Confirm the exact model, nozzle, cable, local price and return terms with the seller.
