## Customer Reviews

### ⭐⭐⭐⭐⭐ Just right for band rehearsals.
*by A***Y on May 1, 2021*

I play in a 5 piece band that rehearses with a PA and has a pretty loud drummer. The 15‘s were blocking out too much sound and I found that the 9’s are just right (where I can hear well enough to sing harmonies on pitch). I will save my 15‘s for when I go to loud live shows.

### ⭐⭐⭐⭐⭐ Work great!
*by G***R on July 5, 2019*

Already have the other db filters, so knew what to expect and how to use these. Worked as expected!

### ⭐⭐ Doesn't last long
*by L***A on August 4, 2023*

What's going on with the glue on these things? Seems like every few months I have to buy a replacement filter cause the glue just gives out splitting the filter in half.
