The next generation in Binaural In-ear microphones have 22dB less noise (hiss), 18dB more sensitivity and 10dB higher max SPL than our standard model. This means that your recording will have noticeably less background hiss and greater dynamic range than previously possible with in-ear binaural microphones! Compare these to the best omnidirectional microphones anywhere and you will see why these offer the highest level performance at fraction of the cost of other similar mics.

The MS-TFB-2-MKII Sound Professionals In-Ear Binaural microphones are mounted in extremely comfortable super-soft, In-Ear holders that slip right into the ear structure. Why put microphone here you ask?

Pretty simple, really. There have been many ‘binaural’ 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, 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, 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 very realistic recording. The cables terminate in a stereo 1/8″ (3.5mm) gold-plated miniplug.

    These make great field recordings.

    Recorded with mix pre 3ii , with XLR cable option for the mics. The only editing I did to the file was to run a high pass filter because the massive rumble from all the motorbikes was overbearing, plus fade in/out.

    If you want to get right to the meat of the recording check out the middle part (-4:07 or so) for the very loud bikes and sirens, and also check out the accurate detail of the chimes near the end (-0:30 or so).

    The only minor gripe I have about these mics is that the cables are ultra thin and appear to be quite delicate, but they have given me no issues so far.

    I also have the MKI version of these mics, and these are definitely superior in terms of detail and self-noise. They also sound overall better, in my opinion, then the pair of Uši Pro’s I have when comparing sound quality and noting that they are regular mics and not binaural.

    I would definitely recommend these.
