So basically with this tutorial I can equalize my headphones to flat or whatever I want permanently and use it anywhere? Great and very explaining tutorial but just this one small question. Please reply ASAP. Thanks

It's for both home and outside. I have an Iphone 4S with no amp. Doesn't really matter to me too much. It shouldn't be a completely bass heavy headphone because that's the problem with Beats. It can either be flat or customized. 

I have a moderate understanding of headphones and such but I need help choosing from the headphones that I will list. I have done extensive research on all of the headphones but have trouble choosing one to buy. My budget is up to about $150 at most. Please help out. Thanks  ...
