Geekria’s product page explicitly names SteelSeries Siberia 800 and 840 as compatible and describes replacement earpads.
These are not ranked alongside verified fits.
Compatibility is not fully confirmed. The evidence may involve a model family, generation, or only partial support.
The product listing names Siberia 800 (X800, P800), Siberia 840, and SteelSeries H as compatible. This is a retailer listing, not the manufacturer's own product page, so it is supporting evidence rather than decisive manufacturer evidence.
