Product Description:
Trumpet players no longer have to sacrifice range, endurance or the integrity of their practice during sessions when a mute is necessary. The Brass Spa practice mute is free blowing and does not back up in the lower and upper registers like other mutes on the market. Whether you're on the road, in an apartment, or just want to get in some late night practicing, this practice mute delivers.

Rating : - Works great!
A trumpet player recommended this mute to me personally. Its is quiet and my roommates love me much more than they used to! It never warps the notes and I have no problem with air flow and range. And it is insanely light, I don't know how they did it. I never have any trouble with it staying in my horn either.
