The ones with strings don’t have the same NRR rating as the foam ones and for prolonged wear can be quite uncomfortable. The only guys I see wearing those are in the shop or in an office most of the day and only wear them for a few minutes at a time.
This is why they make them with strings. I don’t have the dexterity to remove them otherwise.
