Effective but maybe too small if you have larger ear canals
The sound quality and protection is good but they were too small for my ears. In order for them to be effective, they had to be pushed in further than they could easily be extracted which resulted in some uncomfortable moments trying to get them out quickly. They are more comfortable than expanding ear plugs and carry a lot more of the frequency range so the music doesn't sound so thin as with other plugs. I am considering trying to swap the tubes into larger double or triple flange inserts or just buying a different brand since these only seem to come in one size.<br /><br />Keys are an effective if somewhat dangerous and uncomfortable method of removal if they get lost and there is no one with nails or a pair of tweezers nearby.
