I use my sony's because i really really love them, they just sound amazing without any unneccesary things.
But, after around an hour of listening my ears start to hurt. the earcups haven't been replaced since my dad bought them around 1990. so yeah.. i need to replace them. but, of course, no one has parts for these old headphones.
Getting other headphones is not an option, as i love these and im as broke as i can be.
