Low Noise In-Ear Microphone – one ear only. Made in USA.

The SP-TFB-1 Sound Professionals In-Ear microphone is mounted in an extremely comfortable super-soft In-Ear holders that slips right into the ear structure. It is worn this way while recording and produces an extremely realistic recording. This is accomplished by having the microphone element right next to the opening of the ear, well inside the ear structure. While recording, your hearing is not impaired, so you can hear normally while making very realistic recording. The cable is 59”  in length and terminates in a 1/8″ miniplug. This mic is excellent for recording telephone conversations (where it is legal to do so) as it will pick up both sides of the conversation.

IMPORTANT NOTE: Because this microphone (and optional windscreen) is used inside the ear structure, it is not returnable for exchange or refund. The normal year warranty still applies.

Available Options:

Since there are some variances in the shape of the human ear, and especially for customers with larger than average ears, and/or for windy situations, soft foam windscreens are available (choose windscreen option above). These windscreens are acoustically transparent, and allow sound to pass through to your ears and the microphones completely unchanged. They are shipped in natural off-white color (see pictures below) and are easily dyed with common household dyes available at your local supermarket. These are also handy for those recordists who need the microphones to be very unobtrusive as they completely cover the mic element.
