Bose A20 Replacement Ear Seals (Aftermarket)

Will these ear seals fit my Bose A20 headset?

Yes. These aftermarket ear seals are made as a direct replacement for the original cushions on the Bose A20 aviation headset. They are engineered to the A20 specifications for a secure snap-in fit that re-establishes the acoustic seal. They are a compatible alternative made by PilotMall.com, not an OEM part manufactured by Bose.

Are these genuine Bose parts or aftermarket?

These are a high-quality aftermarket product designed by PilotMall.com as a compatible alternative to the original Bose A20 ear seals. They are not an OEM part manufactured by Bose. For many pilots this is a cost-effective way to restore comfort and the acoustic seal of the headset without paying for original manufacturer parts.

What material are the ear seals made of?

Each ear seal is made from a soft, pliable protein leatherette wrapped over plush foam. This combination is built for comfort during long hours in the cockpit while holding a snug shape that keeps the acoustic seal against your head. The protein leatherette gives a smooth, comfortable feel against the skin.

Do new ear seals really improve noise cancellation?

Yes. A proper, tight seal is essential for maximizing both passive noise reduction and the effectiveness of your headset Active Noise Reduction system. When old cushions crack, flatten, or flake, the seal breaks down and quiet suffers. Fresh ear seals re-establish that critical seal so your A20 returns closer to peak performance.

How do I know when my ear seals need replacing?

Replace your ear seals when the covering is cracking, flaking, torn, or flattening, or when the headset feels less quiet and comfortable than it used to. Worn cushions lose their shape and let sound leak past the seal, which reduces both comfort and noise reduction on long flights.

How often should I replace my Bose A20 ear seals?

There is no fixed schedule that fits every pilot. Replace them whenever the covering starts cracking, flaking, tearing, or flattening, or when the headset no longer feels as quiet or comfortable as it once did. Pilots who fly often may notice wear sooner, so inspect the seals periodically and refresh them when they degrade.

What shortens the life of aviation headset ear seals?

Wear comes from normal contact and friction over time. Facial hair such as a full beard can speed up wear at the seal edge, and exposure to extreme heat or cold can stiffen or crack the covering. Storing your headset properly between flights and avoiding excess strain on the cushions helps them last longer.

How do I keep my ear seals clean?

Wipe the protein leatherette covering gently with a soft, slightly damp cloth and let it air dry before storing. Avoid harsh solvents or soaking, which can break down the surface and the foam underneath. Keeping the seals clean and dry helps preserve the smooth feel and the snug acoustic seal against your head.

How are the ear seals installed and do I need tools?

Installation is designed to be toolless. The ear seals snap into place so you can refresh your headset quickly. Peel off each old cushion, line up the new seal over the earcup, and press it down evenly around the edge until it seats. Take your time working it around the full rim so it sits flush.

Are these ear seals sold individually or as a set for both earcups?

These ear seals are sold as a set of 2, one for the left side and one for the right side, so a single purchase covers both earcups.

Will these ear seals also fit the Bose A30, A10, or Bose X headset?

These aftermarket ear seals are engineered as a direct replacement for the Bose A20 aviation headset. They are not designed for the Bose A30, A10, or older Bose X models.
