used to use the foam ear defenders but they used to block so much it made me feel isolated also they affected my balance something to do with the air in the ear canal not being able to move when cornering etc which i thought was bs until i found an article about it (would post a link but cant find anything online now) before i found the article i thought i was imagining it.

now use Auritech, did try the Pinlock ones but they come in a storage box which is a faff when getting them out and putting them away, the Auritech go in a screwtop tube which hangs round the neck much easier
