New! The next generation in Binaural In-ear microphones have 17dB less noise (hiss), 10dB more sensitivity and 10dB higher max SPL than our standard model. They measure an amazing 19dB of equivalent self noise. 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 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.

Recommended accessories:

Windscreens: 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. These windscreens are acoustically transparent, and allow sound to pass through to your ears and the microphones completely unchanged. They are available in tan and standard black. These are also handy for those recordists who need the microphones to be very unobtrusive as they completely cover the mic element.

Microphone power supply (Battery Modules): For loud recording situations, the mics need more power than typical recorder can provide. You can also use battery module to adjust bass response and adjust levels. See the details on each module for features and specifications.

    I bought these microphones for binaural audio voice recordings. Background noise is very low while the microphones pick up everything else making it sound crisp and clear.Where this product truly shines is in just how life-like the sounds are. In the past, I’ve had my dog jump down from my bed while I’m recording. Upon listening back on the recording many hours later, it sounded EXACTLY like my dog had just jumped off my bed behind me to the point I couldn’t tell if the sound came from the recording or not. I was amazed at that. Great product. 10/10 would bang

    Ok, here’s the scoop, I am a total neophyte when it comes to recording anything, especially live musical performances. I got the most amazing recording–no noise, incredible tone, rich and silky smooth up and down the scale my very first time (which was last month). It’s actually hard to believe how good my recording was. I happened to hear a recording of the same concert with someone (a) using a $600, 3 lb Marantz versus my $200 Roland R-05, that weighs about 8 ounces and fits in jeans pocket (b) they extensively mastered their audio afterwards; mine came straight off the SD card.I probably had a better seat to record from and sure, I recorded at a higher bit rate than this guy but I have trouble he would have had results to match (or at least exceed) my binaural recording, given how muck more details and depth I had in mine. Oh, and by the way, he was using $2800 Schoeps CCM 41V microphones…!

    Purchased the MS-TFB-2-MOG-XLR Ultra low noise In-Ear Binaural microphones. Excellent binaural sound quality with low noise. The XLR option allows one to use with mic preamps with 48v phantom power like the ART Pro MPA II studio grade stereo mic preamp.I used the binaural mics to measure headphones: to compare speakers: sound quality with bass response to below 20 Hz. Fantastic product for the money

    The in-ear binaural microphones from the sound professionals bring to life, the audio around you. If your looking for a complete 3D emersion, you need to look no further. The new Master series brings up the volume, and down the noise making recordings that much more life like. The shielded cable option truly shields, it’s like I’ve got XLR cables but I’m only using a gold plated 8th inch running into my Zoom H1 recorder. If your wanting to record high volume sounds such as loud music or loud bangs, I’d suggest you invest in a power module, as my experience with the H1 clips easily.

    Great Microphones!

    I have used these for years to record live classical music, and it’s important for me to get the both highest and lowest tones just right, without missing any of the music’s finer parts. These microphones are always good for that. However, to some extent, stereo microphones are magical: the same brand, the same supplier, the same model, and you can get a bad set or a phenomenally good set. If you stumble onto a good mike, you keep it for decades. I have found that these microphones are often better than even the most expensive brands.

    I recently got my hands on these in-ear binaural microphones, and I must say, I am absolutely thrilled. As an audio enthusiast, I’ve been eagerly waiting for a chance to try out this cutting-edge technology, and these microphones seem to be exactly what I’ve been searching for.

    The design alone is striking, and it’s evident that these microphones represent a significant leap forward in the world of audio recording. The binaural concept, with microphones placed precisely in your ears, promises to deliver a listening experience that is incredibly immersive and lifelike.

    I have high expectations for these microphones, and I genuinely believe they won’t disappoint. The prospect of capturing sound from a perspective that mirrors the way we hear naturally is incredibly exciting. Whether it’s for ASMR recordings, field recordings, or just enjoying music in a whole new way, these microphones seem poised to excel.

    The anticipation is building, and I can’t wait to put them to the test. From everything I’ve seen so far, the combination of technology and design is genuinely innovative. Stay tuned for my full review after I’ve had the chance to try them out. I have a feeling these binaural microphones are about to open up a new world of audio possibilities!

    Recently purchased the MS-BINAURAL-BUNDLE-2 to build a binaural dummy head for a client. These are specifically the MS-TFB-2 – Ultra-low noise, in-ear Binaural microphones. The IOS adaptor is huge bonus! The flexibility of recording with an iPhone on the go makes things super convenient!

    I had previously bought the same microphones for my own build several years ago. You can hear the results in an episode of the podcast Campfire Radio Theater called “Abduction at Willow Woods”.

    I know it’s not a Neumann head but for my money these little microphones produce excellent results particularly if you take them out on location to record actors or sound design! Very realistic 3D effect with low noise! I used a diy dummy head with silicone molded ears, recording with a Zoom H2N.

    An excellent set of binaural microphones.

    I have listened to various recordings of different binaural microphones, and these still continue to provide excellent quality and binaural audio, a flat frequency response, and low noise in comparison to other microphones I’ve heard or dealt with myself. I’m pleased that such microphones are still available, and hope to continue enjoying them for quite some time.

    I purchased the MS-TFB-2 binaural microphones to use with my GoPro Hero 11 Black camera (with GoPro Media Mod) for recording activities outdoors (in stereo) and especially for a forthcoming helicopter tour I will be taking that I can record the pilot’s dialogue that will be piped into our headphones (and our conversations with him) during the tour. I took a helicopter tour several years ago and videoed it but since we were wearing headsets none of the dialogue was picked up by my video camera and recorded, only the noise of the helicopter blades and engine. I have unscientifically simulated this situation with the MS-TFB-2 by plugging it into my GoPro camera (and of course into my ears), setting up my computer to play music and dialogue videos on my computer and piping the videos’ audio via Bluetooth into my Bose over-the-ear headphones, recording the video with my GoPro while capturing the sound with the binaural mics in my ears underneath those Bose headphones. I tried both the Standard Mic and Standard Mic+ external mic GoPro settings (20dB increase on the latter). In both cases, playing back the GoPro recorded video/audio, the music and dialogue audio were captured by the binaural mics without any issues to my untrained ears. The real proof for me will be when I take the helicopter tour, but so far it the recording is sounding clear and as I hoped. I do have a couple of issues with the binaural mics – I have large ears and the mics do not fit as snugly in my ears as I would like. Also, I purchased the foam windscreens for the mics, but they do not secure onto the mics, instead you just put them in your ears after you have placed the mics in your ears. I haven’t tried recording outside with the wind blowing to see if/how the windscreens work and whether they stay in or pop out of my ears (they do not appear to fit in my ears very snugly either) and to of course see how much the wind noise is reduced by them versus the noise without those foam windscreens. So, some more testing to follow, but initially I am quite satisfied with the mics and the quality of the recordings.

    I have had the first version of these mics for years. now I love these as well! they are the same in-ear design that I know and love, but the cable option is better and the mics are way less noisier! They are nice and stealthy as well, very easy to where and so small you tend to forget that they are even there.

    I recently purchased this binaural microphone to experiment with head related transfer function (HRTF) as I am aspiring to work as a sound engineer. While I have not extensively tested the microphone yet, my initial impression is positive. The mic appears to have very low distortion and seems to be highly accurate in capturing sound.

    I am looking forward to using the microphone more extensively in the future to fully explore its capabilities and potential applications. I plan to conduct more tests and experiments to better understand its performance and how it can enhance my work as a sound engineer.

    I will provide a more detailed review once I have had the opportunity to use the binaural microphone in various scenarios and fully assess its capabilities.

    Developing an idea that’s been brewing since 1992… and now technologically mind blowing what the possibilities are. I’ve only scratched the surface on these binaural mics possibilities. But the tests have been astonishing. Consider me a fan of the Sound Professions!

    These binaural mics have changed my life!

    I purchased this product for BRIR measurements and it works perfectly!
    I bought it with a 3.5mm connector because I was on a tight budget, but if I had it to do over again, I would buy it with an XLR connector.
    The soft earfin acts as the housing, so be careful when modifying it.

    I’m so pleased with these. I’m having the opposite of buyer’s remorse, where I keep finding excuses to take these out to record music, the outdoors, city walks, you name it.

    Bought them to try recording some outdoor festival sets over several days and cannot believe how well they performed. No discernible noise, incredible detail, with a good pair of headphones I can close my eyes and listen to the recordings and I’m transported right back to where I was, with a natural-sounding reproduction of place and space. With a pair of tan windscreens the mics were comfortable over several hours, I could still hear perfectly, and I didn’t draw any attention at all.

    I’ve ordered a battery box to give the mics dedicated power instead of having my audio recorder supply it. It doesn’t seem to be strictly necessary in my case given the quality I’m seeing so far, but it should help keep things tight in high-SPL conditions.
