Just got those and they sound horrible at high volumes and barely have any bass...they sound nice when plugged in to my MacBook but I mainly need these for work.
I understand there are portable amps but I don't want to go that route...Are there any headphones with built-in amps or something so they sound better that these, specially for use with my iPhone 5S at work?
P.S. even my Panasonic RP-HTX7 sound better with my iphone than these!!
