Wicked Cushions explicitly lists these WC FreeZe cooling-gel replacement earpads as compatible with Sony INZONE H9 and WH-G900N. The page describes them as thicker than the original pads and makes sound/isolation claims; its FAQ acknowledges replacement pads can affect noise cancellation or audio quality. Those are manufacturer statements, not independent performance verification.
