The Budget 700$ max
What headphone should I get ?
Not a headphone, just use equalizer. The only headphones with better bass than HE500 are Audezes, and they don't go for $700. If you want more (rather than better) just use equalizer, seriously. Or just give up on hi-fi headphones, the point of high fidelity is having the right amount of bass, not emphasized bass.
I was talking about the Signature DJ (since you wanted more Bass!), but the Signature Pro is good as well (the Signature DJ has a bit more bass quantity, bigger/wider soundstage, a bit more airier than the Signature Pros).
