The SP-TFB-2-IPHONE Sound Professionals In-Ear microphones are mounted in extremely comfortable super-soft, In-Ear holders that slip right into the ear structure. Why put a microphone here you ask? Pretty simple, really. There have been many microphone designs over the years…….mics built into fake heads, built into Croakies, made with clips for attaching to glasses, built into headphones and earbuds. All of these have one flaw……none actually put the mic element in the best possible place for the most realistic recording – within the Pinna (the part of the human ear that is visible – the folds on the outside). Even earbud Binaurals have the mic element outside the Pinna. Because everyone’s Pinna is unique, a recording made in your own ears will sound the most realistic. These mics put the mic element right next to the ear canal, well within the Pinna. This results in the most realistic recording possible directly into a Smartphone/iPhone headphone jack, from the perspective of the person wearing them.

While recording, your hearing is not impaired, so you can enjoy the sound of the performance while making a very realistic recording. The cables terminate in a 1/8″ (3.5mm) gold-plated 4-pole miniplug. 

NOTE: Since the headphone input on a mobile device does not support stereo recording, even though this product has 2 microphones, you will be making a mono recording. If you want to make a binaural or stereo recording, use the SP-TFB-2 or MS-TFB-2 and this interface.
