I have a few for different purposes. My go to set is my AKG K44. It is as light as earphones, gives a good audio colour for casual listening and basic. The biggest issue with it is that it leaks out sound that might be noticeable in quiet settings. It is around £20.
My most preferred is however my Sony MDR7506. So good that I have two. I do recordings and these don't leak any sound into a condenser mic which picks up a lot of ambience. This is a bit above the budget but is quality. I even bring them on air travels because the children gets ear aches, these are the only things that help. I don't know the mechanics behind it but the MDR7506 is true closed back. For listening to music, this might be of a bit flatter colour but the range it adds is the heightened sense of hearing. Be aware of counterfeits though, this set is one of the few headphones that have been faked to death.
In between I have an Audio Technica ATHM50x and a Sennheiser HD202 which are both rarely used but decent in their own levels. I have a few Behringers that are too warm to the ears.
I've also heard good reviews about Koss for casual listening. And the Sennheiser HD201 has had a lot of happy buyers too. If a quality headphone is needed I would go for the Sony MDR7506 or semipro ones from its MDR series.
Obviously I love headphones and microphones.
