All verified earpads
Fit details and supporting evidence.
- Part number
- EPZ-HIFIMAN (variant suffix varies by material; product page shows EPZ-HIFIMAN-FNSK for Fenestrated Sheepskin)
- Dimensions
- Product page lists A 111 mm, B 105 mm, C 65 mm, D 60 mm, E 30 mm; measurement labels are not defined in the retrieved text.
- Mounting
- Replacement pad product; the cited product page does not specify the attachment mechanism. HE400i manual documents flange-to-rim snap-in mounting for the headphone’s pads generally.
- Sound / ANC
- Aftermarket pads offered in multiple materials. Dekoni states that material/construction can customize tonal signature; no claim of stock acoustic equivalence is established here.
Evidence (2)
-
down.hifiman.com
Confirms the HE400i’s general pad mounting method: the mounting flange fits onto the earcup rim and is pressed until it snaps into place. It does not establish Dekoni-specific mounting.
-
dekoniaudio.com
Dekoni explicitly says its circular HiFiMan pads fit HE400i, identifies its four material variants, and discusses HE400i-specific pad measurements and sound comparisons. It states that the tested HE400i stock pads are pleather/velour hybrids.

VelPad (HE400S stock earpads)
Compatibility is not fully confirmed. The evidence may involve a model family, generation, or only partial support.
- Dimensions
- Inner diameter approx. 54 mm; outer diameter approx. 106 mm; thickness 25 mm at thickest and 16 mm at thinnest.
- Mounting
- Mounting system; exact attachment detail not specified on the product page. HE400i manual says the pad’s mounting flange fits onto the earcup rim and snaps into place.
- Sound / ANC
- HiFiMAN describes the VelPad as beveled and designed to direct the planar drivers toward the ears. The HE400i manual says to orient the thinner portion toward the front and thicker portion toward the back. The manufacturer lists the VelPad as HE400i-compatible, but does not establish acoustic equivalence to the HE400i stock hybrid pad.
- The evidence supports only part of the fit claim or a related model/family, so exact compatibility is not fully confirmed.
