    • Q:

      BP894 question.

      I am a radiologist dictating cases all day long and currently use the PRO8he with a 3.5 mm connector to a Buddy7G USB connector into our speech recognition computer. The recording quality with the PRO8he is incredible which increases speech recognition accuracy but it is somewhat uncomfortable for long periods of use. I am considering the BP894cLM3 as an alternative thinking it would be more comfortable for long periods of use. Would I anticipate the recording quality to be as good as the PRO8he with this unit and is the BP894cLM3 the correct item to order to obtain a 3.5 mm connector? Also, would the BP894 series be considered comfortable for long periods of use? Thanks for your help!

        Thank you for your inquiry. This will not work. This microphone is designed for use with a Sennheiser wireless system. I do see any convenient way to make this work for you.
