Replacement Ear Pads for Synchros E40BT E40 S400

These replacement ear pads fit the Synchros E40BT E40 S400 S400BT headphone models. They use PU leather and soft foam for a comfortable seal. The pads arrive as a pair so both sides can be refreshed at once. They are intended for listeners who want to restore worn cushions without buying new headphones.

Upgrade From Worn or Lost Original Cushions

The pads replace original cushions that have flattened torn or gone missing. A swap is worth it when the old pads no longer seal properly or cause discomfort during long sessions. The 15mm thickness and 72mm outer diameter aim to restore the original fit. Buyers who need a different material or a larger inner opening should look elsewhere.

Simple Press On Installation

Installation requires pressing each pad onto the earcup until it seats evenly. The flexible foam helps the pad conform without tools. What usually goes wrong is an uneven seat that leaves a gap and reduces isolation. Align the 32mm inner opening with the driver before pressing firmly around the full circumference.

Questions about this item

Will the 72 mm outer diameter and 32 mm inner diameter fit my Synchros E40BT earcups?

These pads are sized at 72 mm outer diameter and 32 mm inner diameter, matching the Synchros E40, E40BT, S400 and S400BT models listed.

How do I install the pads without tearing the PU leather?

Stretch the elasticised inner lip over the earcup rim, working gradually around the 32 mm opening; avoid pulling from a single point to prevent the PU leather from splitting.

When should I replace these PU leather and foam cushions?

Replace the pair when the foam compresses below the 15 mm thickness, the PU leather cracks, or the pads no longer seal against your ears for noise isolation.
