I'm with [MENTION=11587]MatthewAMEL[/MENTION]. Tried LS Zulu, A20, DC and more at my last job flying long days. PF2 is much more comfortable with custom earpieces. I have noticed a bit of environmental noise from most every microphone, so I'm looking for a better microphone cover, but other than that, I'm very pleased. I've not been here long, but I'd spring for the BT, if only to make phone calls without missing radio calls if/when I upgrade to the left seat. CAUTION! Fly them for a few weeks before you make a decision. There is a little break in period on the new ear pieces. I used a little Aquaphor on them until they were broken in.
