Adams Aviation are most excellent about headset advice. I would highly recommend them. The only confusion is there are at least 3 Steves, so always get their surname. The last place to go is
www.Flightstore.co.uk as they have no knowledge about the products only what is written on the box. I had a really funny conversation about the Bose A20. He kept pronouncing it Bossy. I said its Bose but he did not listen he just kept saying the same thing. So they no nothing and obviously cant read either. It was like a comedy sketch. So definitely Adams aviation. Depending on where you are if you pop in and see them they will give you really good time and advice.
