I've had a pair of audio technica A700s for almost a year now, but one of my step brothers used them and broke the right headphone off. I have it held on with duct tape at the moment, but it doesn't hold very well. I was thinking about either picking up another set, since I quite like these, or...

I'm looking for some new headphones for my computer to replace the headset I have now. I was recommended Audio Technica ATH-AD700s and AKG K240's. I saw in the sticky that they were both recommended for my price range ($70-$150). What are the differences between the two?
