DC Pro X
I bought a set of DCs and I am very happy with them. Lightweight, comfortable on long trips, ANR works great!
However, I found one drawback:
Our company operates a couple of CL 605 and 604, and they don't work in the right seat. There is a loud background noise as soon as you connect them. After I experienced that, I tried the headset on all our company airplane with the the same result.
On the left side they work great!
