Gotta agree with Rainboe on this. I used my bog standard DC head set all the way through flying training, flying the 146 (not known for it's quiet flight deck) and on the Q400.
I did try a set of ANR sennheisers on the Q400 and the difference between those and the DC's was negligible.
In my opinion spending a few hundred quid on a 'lifestyle accesory' is daft when that money could buy you a couple more hours of flying or a months worth of beer.
Oh yes, the results of my audiograms haven't changed over the last 15 years so damaging your hearing by wearing a 'normal' headset is probably a load of old nonsense
