BEST BRASS trumpet e-brass IV mute

Electronic practic mute.   

Superior volume reduction; even equal to a soundproof room. 

Despite being quiet, it is incredibly free blowing. 

World’s smallest and lightest all-in-one e-mute. 

e-Brass reduces instrument output to a whisper, lowering volume approximately -30dB to -35dB. With its amazing quietness, you don't have to worry about disturbing the neighbors and also can enjoy playing the instrument without feeling self-conscious about other people listening. Using the e-Brass is just like playing in a completely portable and personal studio where nobody can bother you. 

e-Brass comes with a connecting cord, which will facilitate interactions with PC, MP3 players, or recording devices, so immediately after your purchase, you can enjoy Music Minus-one or a play-along recording (eg. Jamey Aebersold) with its 1/8 audio-in jack.
