Price trend
14 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
10 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $89 and $175. The full range runs 2.9× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
Earpads and headbands are consumables and often need replacement — check whether replacements are still available for the model. On planar and electrostatic designs, confirm the drivers are undamaged, since these are rarely economically repairable.
This range reflects 10 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
