A common issue with Koss Ur-30 headphones is the ear foam degrading over time with sunscreen and bug repellent. Here we have a soft ear padding that's actually better quality than the original, its a larger ear with larger padding and better wind resistance.
These come with a warning changing them over is a bit tricky you need to loosen off 3 screws to remove the old set and getting the new pads in can be a pain so if you're not good with a screwdriver and fiddly tasks maybe ask a mate to help who is.
Worth Noting these are not Minelab endorsed aftermarket parts these are parts we have sourced via a factory in China who make replacement ear pads.
Opening up your earphones yourself will void your warranty if its still valid!
