Replacement Headband Cushion for JR-Series Headsets

This blue sponge cushion replaces the worn head beam pad on JR300, JR300BT and JR310BT children's headphones. It protects the original headband from dirt, sweat and daily wear while restoring comfort for young listeners. Installation requires no tools and takes only seconds. The part measures approximately 122 by 22 millimetres.

Upgrade from a flattened or torn original pad

When the factory cushion loses its elasticity or shows visible damage, this replacement restores the proper fit and hygiene. The jump is worth it if the headband feels hard, slips during use or has absorbed moisture that cleaning cannot remove. A fresh pad extends the usable life of the headset without buying a new unit.

Suits parents repairing a child's JR300.

Buyers needing a different colour or a cushion for another headphone model should look elsewhere. This single piece fits only the three listed JR-series variants and is sold in blue only.

Questions about this item

Will the 122 mm by 22 mm cushion stretch over the JR300 headband?

The sponge material is soft and elastic so it stretches to fit the JR300, JR300BT and JR310BT headbands.

How do I swap the old pad for this blue one without tools?

Peel the worn cushion off the head beam, align the new sponge pad and press it into place; no screws or adhesive are required.

When should I replace this sponge cushion again?

Replace it once the sponge loses elasticity, tears or becomes unhygienic from sweat and dirt buildup.
