### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfectly fits in the JBL studio 530 bass port
  

*by E***S on Reviewed in the United States on May 2, 2023*

Like the title says I bought these to plug the ports on a pair of JBL studio 530s that I bought second hand. These fit great and stay in. They're solid rubber and feel solid.

    The best for the price

Works great. Happy!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fit 30mm openings better than #6 stoppers.
  

*by F***N on Reviewed in the United States on April 9, 2021*

These solid rubber stoppers are indeed solid, and require some effort to push into and pull out of openings, but are a better fit for 30mm openings than #6's.  These are made of very dense rubber and are impervious to wear and tear, and seal good if pushed in hard enough.
