Hi Psycho
I want as simple solution as possible, I'm not to bothered about mic.
For instance although over my budget I was looking at Sennheiser RS180 wireless headphones as this will work through my denon avr x2000 which I run all my devices through.
What do you think?
They are good but your paying a lot for the functionality rather than sound quality. e.g. The RS180 is probably comparable to HD558's or something like that (which I own, but only cost me around £80 brand new and can be modded into HD598's for free).
That AVR should have a decent DAC and AMP within it to power headphones, if you don't care about having a mic then get the best pair of headphones for your budget.
Q701 IMO would be the best for competitive gaming. A modded Q701 (bass port mod) for all rounders.

He seems to like them but a lot of people don't rate a lot of what he says. Head fi should have a lot of info on wireless headphones too but ultimately wired > wireless and costs less too to achieve the same sound quality. Spend the same amount on wired as you would on wireless and generally you end up with better quality.
I see the appeal of wireless though and that is why I bought the wireless mixamp over wired versions. I cannot have a wire trailing across the room where it can get snagged or ripped out by someone damaging equipment.

wireless headsets (which are decent quality) like the above IMO are overpriced too, which is why I opted for the 5.8 mixamp for £60-£80 (which is now very rare and hard to find as it's in very high demand and been EOL for several years now) and a set of decent headphones like the Q701 which only cost me £120 brand new from America (£200-£300 here in the UK with a RRP of £400) but I waited to buy them and I upgraded several times.
I spent <£30 on my first set of decent headphones brand new Panasonic HTF600 then HD595 £75 second hand, then HD558 £80 brand new then Q701 £120 brand new.
The Q701 is end game in terms of competitive gaming and sound quality for the money I will never find a better headphone than that. To beat it you need to spend around £300 or more for minimal improvements, the £95 deal from America was a steal and quite a large number of forum members in sound city bought it, in fact there are 2 HUGE threads in sound city about that particular headphone thanks to me.
If you really want wireless then RS180 (headphones only) or a 5.8 mixamp (headphones + mic) are your best bet tbh. If you can get away with wired, grab yourself a set of Q701's for similar money (a guy is selling his in members market for cheap, second hand ones though) and plug them straight into the AVR.
