Yamaha SB7Xc Silent Brass System for Trumpet

SILENT Brass allows you to practice when you want, where you want! With the included earbuds, you can hear yourself playing while people around you hear only a whisper. This complete system includes the PM7X practice mute, the STX receiver unit, earbuds, a cable to connect the mute to the receiver, and an additional cable to connect an external music device so you can play along with your favorite songs or "minus-one" tracks. Please note: Yamaha discontinued the SB7XC in 2016 and replaced it with the SB7X-2.
