This is my second set of these and I'd buy them again. Very useful for live music.

Seems like a good quality product but just got it so we will see how quality is over time.

[This review was collected as part of a promotion.] I thought there would be a hole in them but there isn't. Sounds don't get through so well. Faraway sounds are muffled while close sounds almost go away. I've had people sneak up behind me more often, which I don't enjoy. They're also painful when I first put them in, but get more comfortable the longer I have them in. But when someone wants to talk to me, because close sounds are so quiet, I have to take one out both out and start the process all over again.

They are very stiff in the ear and therefore very itchy and uncomfortable.

[This review was collected as part of a promotion.] I had high hopes for these earplugs but I found them to be less flexible than my silicone earplugs. They were uncomfortable in my ears despite trying several insertions and trying wetting them as suggested. Also could not get a tight seal in my ear canal. Overall a disappointment

Super disappointed. Recommended by my audiologist. Too stiff, couldn't get into my ear. No alternate sizing capability. I ordered standard size. I wanted to like these, they have a lot of technology behind them. Doesn't matter if you can't wear them. Who can cram over 1/4" of plastic into their ear canal? I have better luck with Loop earplugs. :-(
