Review: quality purchase - Decent mute. Currently being used for high school band and works perfectly. Will use more for Jazz band. Good purchase for a non-professional musician.
Review: Effect sound reduction - Took this on vacation so I could get some practice in. It cuts the volume to where I doubt anyone in the building can hear, and it plays well. Pitch is not affected and it does take a little more airflow, but it makes practice possible. It stays in the bell, and takes up very little room in your case. Like a silencer for a gun, with this you could kill a passage and no neighbors will hear it!

### ⭐⭐⭐⭐⭐ quality purchase
*by T***. on March 21, 2026*

Decent mute. Currently being used for high school band and works perfectly. Will use more for Jazz band. Good purchase for a non-professional musician.

### ⭐⭐⭐⭐⭐ Effect sound reduction
*by H***P on September 30, 2025*

Took this on vacation so I could get some practice in. It cuts the volume to where I doubt anyone in the building can hear, and it plays well. Pitch is not affected and it does take a little more airflow, but it makes practice possible. It stays in the bell, and takes up very little room in your case.

### ⭐⭐⭐⭐⭐ This allows fairly normal air flow with a good sound reduction. It helps with my practice
*by K***M on November 22, 2025*

If you want to practice, without scaring pets or disturbing neighbors this is for you. I play a few stringed instruments. I wanted to be able to practice a trumpet. I first tried a standard 'trumped mute', bad choice. A cork in the tube messes with the needed air flow badly. This device seems to have the ability to allow for normal air flow, and still greatly reduce the volume. I am a sub novice with the trumpet but I do heartily recommend this.
