Step-by-step guide to replacing ear cushions on Koss Porta Pro headphones. Includes tips on choosing replacement cushions and avoiding common mistakes.
Quick answer
To replace ear cushions on Koss Porta Pro, gently stretch the old cushion off the speaker housing, align the new cushion's groove with the housing rim, and press it evenly into place. The whole process takes about two minutes per earcup.
Choosing the Right Replacement Cushion
The Koss Porta Pro uses a standard on-ear cushion that attaches by stretching over the speaker housing. The Sporta Pro Ear Cushion (product ID 1668877) is a direct replacement that includes two pairs of ear cushions and two pairs of temporal pads. The FeatherWeight Ear Cushion (product ID 1668871) also fits the Porta Pro and comes with two pairs of cushions, giving you a spare set.
Both options are priced similarly and share the same attachment method. The main difference is that the Sporta Pro set includes extra temporal pads, which can improve comfort on the headband's pressure points. If you prefer a slightly softer feel or want a backup pair, the FeatherWeight cushion is a solid choice.
Step-by-step replacement guide
- Remove the old cushion: Hold the Porta Pro earcup in one hand. With the other hand, grip the cushion near the edge and gently pull it away from the housing. The cushion will stretch and pop off. Work around the rim if it feels tight. Don't yank the cushion straight off; you could tear the foam or damage the speaker grille. Stretch it sideways instead.
- Align the new cushion: Take your replacement cushion (Sporta Pro or FeatherWeight) and locate the inner groove that runs around its back. Position the groove so it lines up with the outer rim of the speaker housing. Make sure the cushion is not twisted. The seam or logo should face outward for a clean look.
- Press the cushion onto the housing: Starting at one point, press the cushion's groove over the rim. Use your thumbs to work the cushion evenly around the entire circumference. You should feel it snap or seat into place. If the cushion feels loose after installation, you may not have seated it fully. Repeat the pressing motion around the rim until it feels snug.
Product facts
- Sporta Pro Ear Cushion: Includes two pairs of ear cushions and two pairs of temporal pads. The extra temporal pads help reduce pressure on the top of your head, making longer listening sessions more comfortable.
- FeatherWeight Ear Cushion: Includes two pairs of ear cushions, giving you a spare set for your headphones. Having a spare set means you can rotate cushions to extend their life, or you have a replacement ready when the first pair wears out.
