Review on David Clark H10 30 Aviation Headset by Bradley Wacks

I'm currently training for a private pilot's license. A friend recommended David Clarke so I bought it. So far they are working very well. I like the soft headphones and the noise cancellation is pretty good. They are flexible and convenient. Not too big. I would say the mic knob loosens at times, I'm sure there is a way to adjust and tighten it, but haven't figured it out yet. I've been using them for about 5 months now and they still work great. I will add comments over time. A good buy in my opinion. Thank you J (1/2/20)
