I bought my audio technica ath-m50x 5 years ago and they are still going strong! I replaced the cable once, but that's the easiest thing ever and my ear pads could do with a replacement, because the Faux leather is flaking off, but I'm too lazy and actually quite like the soft cushion underneath.
I really like the sound and it definitely has an emphasis on bass!
I also have the DT 770 pro, but I actually like the sound of the ATHs better for electronic, bass heavy music, so depending on your music preferences, you could give them a try :)
