Quality made by ROSHO

With ROSHO’s driver microphones, you can always make yourself heard. The new, innovative RFM 310 driver microphone is particularly convenient. This very robust gooseneck microphone is available either with a switch (RFM 310S) or without a switch (RFM 310). It has been specially developed as an excellent alternative to the gooseneck microphones otherwise available on the market for professional use in public transport buses. The driver can announce important information at any time with very high sound quality.
