Price trend
15 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
6 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $100 and $199. The full range runs 2.5× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
Over the last twelve months this model averaged $152 across 3 recorded sales, 12% lower than the preceding twelve months.
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 6 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is enough to establish a working range, but not enough to be precise — treat it as a guide rather than an appraisal.
