Bose QuietComfort 45 Cushion Kit — Replacement Ear Cushions

Replacement ear cushions for Bose QuietComfort 45 headphones that restore comfort and the acoustic seal for optimal noise performance.

The Bose QuietComfort 45 Cushion Kit in Black provides a quick, affordable way to replace worn, torn, or missing ear pads on your QC45 headphones. These cushions are designed to snap on easily and recreate the soft, memory-foam feel that helps the headphones isolate sound and stay comfortable during long listening sessions. Available also in White Smoke, the kit includes both left and right ear cushions engineered to match the original contours and thickness for reliable fit and performance.

How do these cushions affect noise performance?

Worn or compressed cushions can let outside sound leak in and reduce the headphones’ intended quieting characteristics. Installing fresh cushions rebuilds the seal around your ears so your QC45s can perform as designed.

• Restores the circumaural seal that blocks ambient noise.
• Replaces flattened foam that compromises isolation.
• Helps maintain the original acoustic spacing from driver to ear.

Are these cushions easy to replace myself?

Yes — the cushion kit is made for straightforward user installation and requires no tools. Each cushion attaches with a discreet lip that aligns and clicks into the headphone earcup, so you can swap both pads in minutes.

• Tool-free installation — press and rotate or snap into place.
• Left and right pads matched for correct fit and symmetry.
• Instructions typically included or available through Bose support.

Will these cushions fit my existing QC45 headphones?

They are specifically molded for Bose QuietComfort 45 models and will not reliably fit other headphone lines. The dimensions, attachment lip, and foam density mirror OEM specifications to ensure proper alignment and comfort.

• Designed exclusively for Bose QuietComfort 45 earcups.
• Replaces damaged or missing cushions with OEM-style parts.
• Available in Black and White Smoke to match your headset.

What materials and comfort features do the cushions provide?

The cushions combine soft memory-style foam with a smooth outer covering that reduces pressure on the ears. This construction balances comfort for long sessions with the resilience needed to preserve the acoustic seal over time.

• Soft, conforming foam for reduced ear pressure.
• Synthetic outer surface for easy cleaning and durability.
• Thickness tuned to maintain the headphone’s original fit and sound staging.

Who is this for: The Bose QuietComfort 45 Cushion Kit is intended for QC45 owners looking to refresh the comfort and acoustic performance of their headphones. It’s ideal if your pads are torn, misshapen, or compressed, or if you want to replace lost cushions quickly and restore near-original fit and isolation without professional service. Choose Black for a classic look or White Smoke to match lighter finishes.
