Aftermarket replacementVery high confidence
- Dimensions
- Dekoni lists pad dimensions as 118 mm outer width, 66 mm and 66 mm inner measurements, and 58 mm depth.
- Sound / ANC
- Dekoni describes the pads as preserving acoustic integrity, but this is a manufacturer claim; replacement materials may change sound. The product page’s customer feedback mentions increased bass with its leather option.

Tier A · Manufacturer
Philips identifies the target as Fidelio X2HR/00, confirming the headphone identity; it does not make an OEM replacement-pad compatibility claim.

Tier B · Specialist
Dekoni separately states that its X2 replacement pads also fit the X2HR and X3. It discusses possible sound-response changes, including increased bass, so the manufacturer’s acoustic-integrity language should not be read as a guarantee of unchanged sound.
