## Customer Reviews

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    They are probably better suited for long time wear
  

*by C***R on Reviewed in the United States on March 11, 2015*

These are ok ear plugs once you get them adjusted. They are different to wear and are only beneficial when worn for a long period of time. Others tried these ear plugs and were not too thrilled after the initial setup. They are probably better suited for long time wear. The fit is good and the comfort is exceptional.
