first of all what do you want to use the headphones for?
gaming only? gaming mainly with occasional music/movies use?
what pieces of equipment do you want to use with the headphones? we need to know everything so the headphones can be suited to what you have and what you will be using them for.
for the PS4 you will need an amp/dac (mixamp is the best for gaming and the other options which work with pc/smartphones/tablets, etc are better for music/movies)
i'll let you know about my setup so you get more of an idea:
PS4 = Wireless 5.8 Astro MIXAMP (£65 second hand), HD 595 (second hand around £60-£75), DX Clip on Mic (£1.56)
so my console setup cost me around £130 in total (mainly because of the fact you need a mixamp)
PC  - Asus Xonar DG (£15 ish when on offer), Fidelio X1's (£140) for music/movies/youtube/spotify, etc.
Portable - Ipod Touch 3rd gen, Fiio L9 LOD (£7 ish), topping NX1 amp (£20 ish), Sennheiser HD25-1 II's (£140-£180 new)
I pretty much have bought different headphones for completely different uses because they are the best for me for that use.
If I wanted to game on my PC I wouldn't use the fidelio X1's (£140) I would use my dx clip on mic (£1.56) and my HD 595's (£60-£75). Why wouldn't I use my headphones that cost twice as much? Because the HD 595's IMO are better for gaming.
So my gaming headphones are HD 595's, my music and movies headphones are fidelio x1's, my portable are HD25-1 II's.
For your budget I would be looking at CAL's (around £50 on OCUK and come with a free £7 clip on mic), or HD 595's or DT770's (£120-£130).

that's pretty much a good starting point for headphones and are "all rounders" can be used for gaming, music and movies.
