Hi guys I don't know the first thing about headphones but current space constraints are sending me in this direction. The main question that I need answered is whether circumaural types are likely to damage the arms of my glasses. This is something that I will not tolerate for obvious reasons. There are plenty of other threads on headphone choice so I have a rough idea where to start with something between £50 and £100 to spend. PJ Hifi will probably be my first port of call, has anyone used them for cans in this price bracket before?
