That's what I meant by "the headphone world." It's like a resort: all-inclusive.
(Now there's an idea for a theme park.)
In which direction would you look if you were looking for headphones that put out prodigious bass? I'm not exactly concerned about mid and high range accuracy - I have the HD650 for that - but I'm also not willing to go down the Beats route, either. The ATH-M50S is pretty much exactly what I have in mind, but since I've owned it before, I'm wondering if there are other comparable options.
