Boom microphone with 3.5 plug for Phonak Roger Touchscreen teacher microphones. Simply plug it into the transmitter's 3.5 mm jack and it's ready to use. We always recommend having a microphone as close to the speech source as possible for best sound quality. The included windscreen eliminates noise from wind and noisy consonants (s, f, v etc). The microphone has a mount for both ears, making it stable and secure. The cable is long enough to make it possible to have the Touchscreen microphone hanging via the neck strap or in a belt clip.
