I bought this mute to practice at home with my cornet.
Even though its listed as a trumpet mute, the cork seal fits perfectly on my cornet, which can sometimes be a problem for some mutes.
There's a very noticeable difference once you start using this mute, all for the right reasons.
The volume reduction is huge without sacrifice to the quality of sound or tone (which was particularly important to me when I was looking for a mute), especially for mutes in this price range.
Pros:
-Volume reduction is superb for this product, probably the quietest mute I've ever used.
-Still retains a good quality of sound and tone.
Cons:
-A bit dear compared to some alternatives on the site.
Overall, I would definitely recommend this mute to anyone who wants volume reduction over anything else but still wants to preserve most of the sound their instrument produces.
