I am very happy with the smaller sized earplugs. The material is very soft and comfortable and I have no problem wearing them for an extended period of time. If I insert them deeply I can block sound to a large degree, and I can adjust so they aren’t in quite as deep if I want to let more sound through. The “key chain“ holder is great! I have it clipped to my wallet belly bag so I know I have them with me at any rehearsal, gig or loud situation. I think getting the proper fit is essential. I started with the regular sized earplugs and both of the two different sized shells that came in the package seemed too large to insert into my ear canals. I would work to get them in and then if I talked or moved my jaw much it seemed like they would wiggle looser. I returned them to Eargasm and was refunded most of my money according to their return policy. I haven’t had those fitting problems with the smaller size. I wish I had known about these sooner and that I had become more aware and proactive about protecting my ears long ago. I am an amateur musician and have recently noticed some ringing in my ears. I will have my first hearing test at an audiologist at the end of this month. I think my hearing is still pretty good and I want to keep it that way. I plan to get a spare pair of smaller earplugs in case I should lose one of the ones I’ve got.
