Apple produced two microphones under the product name "Apple PlainTalk Microphone". {{Citation needed|reason=Apple has records of one Apple PlainTalk Microphone only, which has the half-oval shape and was introduced in 1993.|date=August 2023}} The first shipped inclusive with Macintosh LC and early Performa models, and was circular in appearance. It was designed to sit in a holder attached to the side of a [[computer display|CRT display]], and be lifted out and held by the mouth when talking.{{Citation needed|reason=This microphone, known as the Apple Omnidirectional Microphone, is only known to have the industry-standard 3.5 mm mic-in jack. No version of it with the proprietary extended 3.5 mm jack is known to exist.|date=August 2023}} The second model was introduced alongside the AV models in the [[Macintosh Quadra]] series in 1993 but was also sold separately. It was designed to be positioned on top of the screen and to be sensitive to sound from the front. Both models had a longer connector, the tip of which was used to provide the microphone with [[Biasing#Microphones|bias voltage]].
