Sony MDR-G51

Sold or Listed Prices

5 market transactions via web search — not HiFi Registry sales.

Understanding the market

Half of recorded transactions fall between $61 and $63. The full range is tight — lowest to highest is only 1.4×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.

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 5 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.
