I echo the comments about UFlyMike. Their boom mike is only $275 and can be paired with an infinite supply of Bose QC headphones that can be had on eBay for next to nothing. The package ends up much cheaper (less than 1/3 cost) and much LIGHTER that the Bose QC20 which is the only product equally as good. Been using mine on the 737 for many years at DL.
