I'm truly amazed at the number of people here that have had comfort issues. Must be a statistical anomaly.....you know, where only the complaints are showing up and the people who are happy (the majority) simply say nothing at all.
These can be worn loose (as has been mentioned several times in this thread). They are very light for their size and have enough clamp (for most) to just let them sit over your ears with no pressure from the top band. Mine sit like that and are perfectly comfortable.
