I flew for 10 years with a trusty DC H10-13.4 and it served me well, until I started driving a 402 on long legs and going to bed with ringing in my ears.
ANR is the only way to go, after extensive research I settled on the Telex 50 D and love it! A mate I fly with got the DC X11 and after trying my headset is trying so send his back and get a telex.
Hope this helps
