Thank you Brian, I will look into it. 

Hi @Maggie F, Thank you for reaching out to us. To connect directly to a phone, you will need to use a special audio interface that is compatible with smartphones. We recommend the iRig Pro Duo. ...

Hi i purchased a 3dio freespace and can only get it to record one side. i know this is an issue with the channels but everything ive tried has not worked. I tried using my phone (google pixel 7) bu...

Hi @Vincent Robert, If you're not seeing the $1,999 USD price, it is because of your location (this will also happen if a VPN is being used). We do not change the price for any customer based on t...

Hi, I try to buy at 1 999$ but I see the price at 2 804$ Do you think you can fix this and give me the 20% BF ?If you make this, I buy one !  ;-) Thank ! 

Hi @Vincent Robert, Thank you for reaching out to us. Our FS Pro II is regularly priced at $1,999 USD (as of Dec 2025). Our Black Friday Week Sale is currently running until 11:59pm tonight, Dece...

Hi @Anup Engineer, Thank you for reaching out to us. I looked up the specs for the DJI Osmos 3. Only a digital microphone can be connected as an external microphone. What we recommend is recordi...

Hello, I just received my FS BINAURAL MICROPHONE. I'm trying to connect it to a DJI osmo 3 but I am having issues. I'm just using TRS - TRRS - USBC string of connections and the osmo does show the...

Hi @Melti Heart, Thank you for reaching out to us. Have you tried replacing the 9V battery inside? If the 3Dio microphone's power switch is left in the ON position while not in use, the battery m...

I got this 3Dio relatively recently (like under a month ago) When I set it up the sound was fine, but now it's not being picked up by my pc at all. I have a 3DIO FS and an AudioBox USB 96.

Hi @Kathrine Phillips, Thank you for reaching out to us. I'm sorry to hear you're microphone is experiencing a ringing sound. A ringing sound, typically caused by feedback, could be due to the mi...

Hello, My 3Dio has been experiencing a ringing issue whenever I talk or cup the ears, but it suddenly stopped one day. It’s been about a year, and then out of the blue, the ringing returned...

Instead of 90-99% isopropyl rubbing alcohol, is it possible to use distilled water and a uv light wand instead?

Hi @Asmr ist, If you wish to disinfect the microphone, we recommend using %90-%99 isopropyl rubbing alcohol. When cleaning, avoid contact with the center chassis enclosure and the screw posts that...

What about disinfecting it after mouth sounds and ear licking? I can't rely on just using paper towel with warm water to get rid of any bacteria on the microphone.

Hi @Joseph Giacoio, I meant the 3D design of the KU100 pinnae. My apologies, I thought you were asking how you could place the KU100 pinnae onto a 3Dio mic. If I understand you correctly, you wou...

Brian; thank you for the response.  What do you mean by "would require the 3D designs"? Im a grad school student in Spatial Audio and have the opportunity to have my pinnae scanned and 3d pr...

Hi @Joseph Giacoio, Thanks for the question. That is not something we offer, but technically this could be done. The KU100 pinnae would have to be adapted to our disc design, and would require th...

Is it possible to swap out the pinnae for, for example, the pinnae from a Neumann KU100?  Thanks Joe

Thank you Brian! We'll try out the new battery and let you know what happens. 

Hi @Cory Lawrence, Thanks for reaching out to us and for the explanation. If the mic hasn't been used in a few years, then I would definitely recommend replacing the 9V battery inside the mic as ...

Hi all, Hope all is well. My partner bought the 3Dio FS (non-XLR) SSL2 a number of years ago and has never been able to get it working. I only discovered this recently so have been trying to sugge...

Hi @behnam nemati, Thank you for reaching out to us. When you are browsing our website from Turkiye, are the prices shown in USD or in Lira? Unless you are using a VPN, our website should display...

Hello, I live in Türkiye and in the MasterCard payment method I can only pay in Lira or Euro but you only accept Dollars.Can you change it to Lira so I can complete my order?

@3Dio Thank you so much! I'm very glad I asked questions first! 😁

Hi @Josey Bowman, Great question! Those solder points are used to connect to a separate circuit board that we use in the XLR model. Connecting XLR outputs directly to these solder points would not...

Hello, While I ideally would like to have the Free Space 2, I found a 3Dio Free Space microphone secondhand to start a YouTube channel(Binaural Escape) and so far it has served me rather well. I us...

Hi @Cansu Duygu İTAL, Thank you for your question. With the 3Dio connected, if you're getting a stereo signal on the RC2 (either confirmed via direct headphone monitoring from the RC2, or via vis...

Hello! I hope you are doing well.I have a 3Dio FS XLR microphone with XLR cables and also a RodeCaster Pro 2 Mixer. On the contrary of RodeCaster Pro, RC Pro 2 allows you to do pannings for left an...

Hi @Sofia Perez, Thank you for your post. I'm sorry to hear you're having issues with your mic. Also, thank you for the video. That is very helpful. It sounds like it’s time to change the ...

Hello, Thank you for your question. While there is currently no way to modify or extend the ear canal of our existing models, we are working on a new model that will have deeper ear canals and wi...

Hello, I recently purchased a 3dio FS microphone and I use the Scarlette Focusrite audio interface. After about 5 uses with extremely cautious care, I began to hear this odd static sound in the au...

Hello, I’m currently using the 3Dio Free Space binaural microphone, and I’ve encountered an issue with the ear canal length. The ear canal on this model seems too short to fully insert...

@kyrie milan Thanks for the question In the end, as I do industrial design, Im working on a bespoke solution tbh Indeed versatility is paramount and have created a marriage between a neumann, 3DI...

Beyond the current project, do you have plans for future projects that might influence your choice of microphone? Would versatility play a role in your decision?

This is exactly the kind of answer I was looking for. Thank you for making it so easy to grasp. Really appreciate your help!

Has anyone tried the foam head trick for binaural recording? I did! I used a cheap craft store foam head and carved ear canals into it. Honestly, the results were... interesting. Definitely differe...

Thanks so much for the reply The non pro looks very similar to the primo capsule (Ive made/modded lots of mics) but of course that all changes with ear canal and post process but make sense now. A...

Hi @Mark W, Thank you for your post. Great question! Apologies for the delay in responding. The reason you see the difference of 9dB and the FS and FS XLR microphones showing a lower self-noise i...

Hi Im looking to buy a second hand FS XLR instead of doing a project (Im an industrial designer and thought a custom dummy head would be cool...like spock or something lol) but Im finding some con...

Hi 성찬 황, It is difficult to tell from a cellphone screenshot whether the imbalance exceeds 1dB. We don't use the method of tapping on the center enclosure to determine any imbalance. If you are l...

@3Dio What I need is not after-sales service, but rather to know if the left-right imbalance shown in the video or image is at an acceptable level for a product sold by 3dio.   When I tap t...

Hello 성찬 황, Thank you for reaching out to us. I'm sorry your mic doesn't have proper L/R balance. We match all microphones to have identical sound output within 1dB between L&R ears. Therefor...

I purchased a 3dio through a second-hand transaction, but the left-right sound balance is not correct. When I asked the seller, they claimed that this is normal and that all 3dio units have imbalan...

Hi @nghi le, If the audio signal is weak, it is most likely due to a weak or dead 9V battery inside the mic. The 3.5mm output on all of our microphones is powered by a 9V battery inside the mic. ...

hi there! I recently received the FS mic as a gift, however the cable was missing. I purchased a third party 3.5mm cable and connected the mic to my Tascam dr-05x, however the audio was very weak. ...

Hi @Kim N Munro, Thank you for your question. Yes, a dummy head will increase the binaural nature of the microphone as it will more closely mimic the reflections similar to a human head. We do no...

Hi, I've heard from a few sources that trying to repurpose a foam head to put between the ears will give better binaural results. Are there any thoughts on this? Thanks!

Hi @Gina Greco, Hmmm, okay thank you. Would it be possible for you to send us an audio recording of the crackling sound? Our email is customercare@3diosound.com. Also, what interface are you usin...
