I’d say generally the earplugs are very comfortable when in use and the sound reduction is excellent, but I feel the medium tips, which I believe are the smallest, feel tight in my ears, so might not suit everyone. The instructions on the packet could be clearer as they say to insert into the ‘ear’ but don’t specifically mention the ear canal, nor the best way to open it up for a good fit. I also feel that when removing, as they feel so tight, it creates a bit of a vacuum when you pull them out, which is a bit uncomfortable. Some way of releasing that vacuum would be more comfortable.
