About this pair
Cracked Synchros cushions make JBL S300 and S400 sessions less comfortable than they should be. These JBL S300 S400 replacement ear pads in gray leather-look finish restore a wipe-clean face and a matching-pair seal for Synchros cups — including S400BT when the outline matches. This listing is ear pads, not the gray headband.
If you searched for gray leather ear pads for JBL S300 S400, ear pads compatible with S300, S400, S400BT, or an everyday ear pads kit for workouts and commute, this aftermarket pair targets that spare. Smooth leather look with an easy-clean surface is the point of the refresh when foam edges crack or the sede leather-look face peels.
What these ear pads are
is the gray leather-look ear-pad pair for JBL Synchros S300, S400, and S400BT. Shared S300 S400 cup mount language on the supplier row means you should still confirm the worn pad outline before stretching a new cushion on. It is not black and it is not the gray headband.
Aftermarket S400 gray vs OEM is a fair expectation check: these are aftermarket gray leather-look replacements unless a listing explicitly says OEM. Treat them as Synchros S400 gray over-ear pads / S400BT Bluetooth gray cushions of the stretch-on style typical for this family. A matching-pair S300 S400 gray install keeps both cups looking even after the swap.
Who they are for
Owners of Synchros S300, S400, or S400BT who need a cracked S400BT pad refresh or a wipe-clean gray Synchros hygiene upgrade. Match the gray color on your cups if you prefer that over black. Skip this page if you need only the gray headband — that is.
JBL S300 S400 ear pads price shoppers who want a kit rather than a full headset replacement land here when the cups still work and only the cushions failed. Commercial shoppers looking to shop Synchros gray replacement pads in stock can order this pair without guessing the part type. Cheap gray JBL S300 S400 aftermarket cushions still need the correct stretch-on outline — compare before you buy.
Install and care
How to replace ear pads on JBL S300 S400: remove each worn cushion, confirm the stretch-on mount on the ear cup, then ease the new gray pad over the rim until it sits evenly. Repeat on the other side so the matching-pair S300 S400 gray look stays symmetrical.
Wipe the leather-look face with a soft dry or slightly damp cloth. Avoid soaking the foam core. Confirm fit on S400BT the same way — product name lists it, but the worn outline is the final check before you stretch the spare on. Keep a soft cloth nearby for quick wipe-downs after long sessions.
