I was using the telex 750 in the Bus and i had to crank the volume up and then the captain would just talk with the boom down and I’m like huh? What? You want flaps? Tell them what? So I brought my DC pros and I will not go back to wearing anything else. Can’t even hear the engines but I think that’s kinda important so I put one slightly off my ear to hear them. Above 18 people take them off and go on the speaker.
