I would second exactly what Morgy has just stated!
I started out with a M/A helmet, reasonable price/qaulity. But when the seperate headset was used, it was a royal PIA for me!! I just could not get on with the headset moving around under the helmet, creating more distractions.
So, purchased the Icaro and bribed Morgy with posh pies to retro fit my M/Avionics headset.
Brilliant combination now.
Still use the M/A helmet for ground handling though.
Not a cheap setup, but qaulity never is......
