Anybody ever use a Sennheiser HMEC 25-KA ANR headset in GA aircraft? I'm wondering if the comparatively light weight and size is worth the tradeoff of "only" 31dB of total noise reduction (passive and active). A set of rugged DCs with ANR, for example, have better overall ANR performance but are significantly heavier and take up more space. I realize it might also be a matter of personal preference and I will have to try various models before I reach my own conclusion but I'd still love to hear some of your opinions (especially those of you with first hand experience).
