So recently my 3 year old set of Turtle Beach PX21s fell apart completely, and so it is time to get a new set of headphones/headset. I am stuck between getting the Astro A40s or some headphones like sennhesier hd598 or other with a modmic. I want your guys' opinions on whats best to do and what headphones are best for gaming and listening to music (Im a bassist and so bass is quite important to me, to be able to crank it up high). I kniw that sennheiser open headphones are very nice having bought a relative a pair of them, but i just want the get the best headphones for my money. My price limit is around £300 with everything but in time i can go higher (for example if i needed a seperate sound card, which is unlikely considering my mobo's built in sound card (i have the asus maximus vii hero)). Ooh and if it can work with my Galaxy S4 that would be great.
