Need Basshead Headphone within 2.5 K

[Fubar]

I need an on ear / over-the-ear purely bass dominating headphone under Rs. 2,000 - 2,500 that I can use for long hours without any discomfort. I am mostly listening to Nu Skool Breaks with artist including Krafty Kuts, Stanton Warriors, Plump DJs, Evil Nine, A-Skillz etc.

I can purchase from online stores only if they have COD facility in Kolkata.

Thanks.
