So I have sort of gotten my friend into higherish end audio but in the end he still liked my Klipsch Image ONE headphones better than my DT770's or Shure SRH840's or Denon D-5000's due to the bass and how loud they can play from a portable. At least I talked him out of beats and having hearing them he likes the Klipsch's better.
He also had a pair of S4's and liked them even better but he destroyed the cord on them and the cord on the Image ONE's cord isn't fairing much better, coming apart by the iClicker. He has also "blown" the Image ONE's, they still work but crackle some times. He is sort of deaf and likes a ton of bass so he listens really loud.
The only thing I can think to recommend to him are the Beats Pro's? Is there anything better that can deliver good isolation and loud sound levels with a ton of bass?
