I am a Bass-Head.  I had a pair of Sony on-ear monitors, and they were uncomfortable and didn't sound good, so I decided that it was time to buy new ones.  I did some research and decided that I wanted a pair of over/around-ear headphones with thumping bass for under $100.  I researched Beats, Bose, Sony, Skullcandy, JVC, Koss, Panasonic, and finally Sennheiser.  I decided to go with the HD 419.  I found them for $35 from B&H and bought them.  They came the same week (with free shipping).  I opened the box, put them on, and plugged them into my iMac...
