No particular axe to grind, but the company use Sennheiser noise cancelling headsets, I have bought a Telex 850 and there is no comparison......been using it for 18 months and now tend to keep it on both ears in the cruise....just watch out when putting your own headset on after crew rest as the other headsets are cranked up to max volume and you barely need to crack the volume button with the Telex.
For what it's worth, I got mine sent to my mailbox in MCO from Marv Golden
