I use these occasionally (after ear plugs started causing problems for my ears). They do a pretty good job in my experience at helping me focus even though they do not perfectly cut out some sounds, everything is muffled enough that it's a peaceful sensation if not total silence.
The bigger issue for me is they really can't be worn more than an hour or so at a time without discomfort.
Basically I wore them for the majority of the hours of the day (during sleep + while working) for over two years without any issues then I had a some pretty major impacted ear wax and started looking into it more. Apparently ear plugs are not really good for you. Which is unfortunate because there is really no substitute.

Out of curiosity, what kind of problems did you experience with ear plugs?
