Review on Microphone Windscreen Foam Muff Cover for Bose Aviation Headset X A20 Telex - HeadphoneMate by Mark Toth

Rubbish as others have stated in their reviews. (1) The foam size is not suitable for A20. (2) the foam does not have enough resiliency to stretch and cover to compensate for the fact that it is not large enough. And (3) the foam is so thin/poor quality that even with careful application you'll break it. In our flight department, 4 pieces were replaced with 4 A20 headphones. and all 4 broken. Finally. The premium for this product is about 250 times. A complete kit costs about $0.25 (O-ring and foam volume). Considering the price they charge, you would think they delivered the PERFECT solution. No, that is not so. Don't waste money.
