Follow these simple steps to fit QZPRO ear cushions on your Koss headphones. Learn the correct orientation, avoid common mistakes, and get a secure fit.

Quick answer

To install QZPRO ear cushions on compatible Koss headphones, stretch the cushion over the speaker housing, align the inner groove with the lip of the housing, and press evenly around the rim until it snaps into place.

Why cushion installation matters

Properly fitted ear cushions restore comfort and sound isolation. A loose or misaligned cushion can affect bass response and cause the cushion to slip off during use.

The QZPRO Ear Cushion is designed as a universal replacement for many Koss on-ear models. Its flexible vinyl material stretches to fit, but the fit depends on correct alignment of the internal groove with the headphone's mounting lip.

Before you start

Make sure you have the correct pair of cushions. The QZPRO Ear Cushion includes both left and right cushions in one package, so you can replace both sides at once.

Work in a clean, well-lit area. Avoid using sharp tools that could tear the cushion fabric. Your hands are the best tool for this job.

Installation steps

Remove the old cushion: Gently peel the old cushion away from the headphone housing. Start at one edge and work around the rim. If the cushion is glued, use a soft pry tool to avoid scratching the plastic. Don't pull the old cushion off in a single yank — this can damage the foam or the housing lip.
Orient the new QZPRO cushion: Hold the QZPRO cushion so the side with the internal groove faces the headphone. The groove should be visible when you look inside the cushion opening. Installing the cushion backward will prevent it from seating properly and may cause it to pop off.
Stretch the cushion over the housing: Place one edge of the cushion onto the top of the headphone housing. Use your thumbs to stretch the cushion downward and over the opposite edge. Work the cushion around the rim, pressing the groove onto the lip. Stretch evenly — pulling too hard on one side can tear the vinyl or misalign the groove.
Seat the cushion fully: Once the cushion is over the housing, run your fingers around the entire rim. Press inward until you feel or hear the groove click into place. The cushion should sit flush and not wobble. A cushion that still feels loose after pressing likely has the groove off the lip — remove and restart rather than forcing it.
Check both sides: Repeat steps 1–4 for the other ear cup. Compare the fit of both cushions — they should sit at the same height and angle relative to the housing. If one side sits higher or crooked, the groove may have slipped. Re-seat that side before using the headphones.
