Fwiw sometimes I wear my APP2 inside my cheap passive 3M earmuffs haha. For an hour or two of use it’s been comfortable enough that I can listen and also attenuate loud tool noise e.g. a weed trimmer.

Of course you don’t get any speech boost to enable conversation with this setup. But no one else around me has passthrough either so I turn off my tools to talk the old fashioned way. :)
