Bose A30 Service Accessory Kit

Make your Bose A30 feel and perform like new again! This Bose A30 Headset Accessory Refresh Kit includes:

• Set of 2 Bose A30 Headset Ear Cushions
• One Bose Replacement Microphone Windscreen
• One Bose A30 Headset Headband Cushion

As a general rule, Bose A30 ear cushions should be replaced every six months or every 300 hours of use, depending on how often you fly.
You may need to replace them more often if you:

• Have a full beard or heavy whiskers
• Subject the headset to severe temperature extremes such as parking your airplane outside in severe cold or heat
• Put excess strain on the cushions because of improper storage
Indications that the ear cushions need replacing include:

• Flaking of the outer covering
• Cuts or tears
• Flattening of the cushion, reducing the effectiveness of the seal against your head

Ensure the performance and comfort level of your A30 aviation headset. Use as a replacement for lost, damaged, or worn ear cushions. Cushions are identical to original set included with new A30 headset and are made of the same supple, breathable protein leather.
While changing your ear cushions, it’s also a good idea to replace the Bose Replacement Microphone Windscreen and the Bose A30 Headset Headband Cushion, both of which are also included in this kit.
