Full size isolating headphones will make your ears hot with extended use. Full sized open headphones give the best sounstage and are the most comfortable. They aren't good when you need isolation though. I use traditional earbuds, IEMs, and open and closed headphones. They each have their place. Sometimes isolation is great, but other times(such as when walking through traffic intersections) isolation can be dangerous.
Headphones do typically last much longer than IEMs. Some people(including myself) are using their Sony MDR-V6 for more than 20 years.
Full sized closed headphones generally give the best bass. IEMs are best for getting isolation without hot ears. Full sized closed headphones can be nice outdoors in the cold weather though(instead of earmuffs).
