I work for a call center and have to wear a headset 8 hours a day and by the end of the day I can always feel my earring posts and backs digging in to me, so I decided to try these. Omg they are so much more comfortable!!! I was worried they might be kind of hard to screw the back on but that wasn’t difficult either, but there is enough thread that I don’t feel like they’ll easily come undone or anything either. Overall very satisfied with this product! I’ll definitely be looking at their other products!!
