We have several MB-1/2 PRO UC mics. Younger users are reporting varying degrees of noise and voice echo feedback from these units. It is quite loud apparently, but it must be at a higher frequency that my older ears can't hear. Some headsets are worse than others and it was made worse after recent firmware upgrades. Tech support (Sennheiser apparently sold off this business) was not too helpful.

The environment is quite noisy (ceiling fans, talking, etc) and 6 users work in close proximty to eachother.

Is this a hardware issue or is it related to Dragon changing the sound? We are using DMPE4.
