I'm looking to purchase a pair of closed headphones that are over ear.
They need to have decent isolation so they don't leak (the outside getting in isn't that much of an issue as it's going to be a quiet place).
They also need to portable, most likely folding for travelling, and with that, they also need to be durable.
Comfort is a huge need. The AD-700 is very comfortable for a standard with not too much clamping force.
Budget is $100, I definiely won't be stretching it any more than that.
It will be run either from a computer or a phone, so no difficult to drive headphones, and music preferences are just about everything (Top 40s stuff?).
At the moment, I don't think that I have many options. All I see are the Sony V6 and 7506, but even then, I'm not sure how their isolation stacks up, but I think that it meets all of the other criteria.
I apologise for being vague, but this will end up being a gift for someone.
