Some time ago (months or more) I read somewhere about a device like this description, intended IIRC for smartphones and other recorders with small internal mics.

It's a small circular piece of foam, with a donut-shaped ring of adhesive around the outer part of the underside. You peel it off the backing paper and stick it on your phone, so the mic is facing through the center part where there's no adhesive.

My recollection is that it's similar in size to the adhesive punched-hole reinforcing rings that we used on 3-ring binder pages, to keep the holes from ripping through.

Now I can't find the thing to save my life. Does anybody recall seeing something like this?

Thanks in advance!

Hi Greg, I do not know of anything specifically made for phones, but Rycote (https://rycote.com/microphone-windshield-shock-mount/lavalier-solutions/) Stickies (with undercovers or overcovers) would work.
BubbleBee (https://www.bubblebeeindustries.com/) also has a line mounting accessories and filters.

Hi Rick. Thanks for the tip. The Overcover may be the product I had seen, and I then extrapolated it for use on phones. I could use a hole punch to remove the center of the sticky, so the mic could communicate directly with the fur. I will definitely keep those in mind, they would work.

If possible, however, I'd like to find a similar product, but foam rather than fur. I think it might be more durable in the long run. I did find phone-specific clip-on products, but I am looking for something with an adhesive attachment. Hopefully someone else has seen such a thing.

Thanks again! Hope you have a good upcoming weekend!

Personally, I like this windscreen that turns your phone into Don King :-D

That phone has more hair than I have!

I use moleskin a lot mounting lav mics on folks, it's would be easy to cut a hole in it. It is very durable the do not leave adhesive goo behind when removed, unlike 3M Transpore tape which I also sue a lot. Dr Scholl's callus and corn pads are circular and some already have center holes.

Rick, thanks for that suggestion; moleskin is a unique fabric/ product. I especially like the idea of Dr. Scholl's pads with the circle pre-cut. However, those circles have adhesive on only one side. So I'd still need to obtain some foam circles, and glue them to the top side of the moleskin. Or am I missing something?

No, you would have to improvise adhesive to attach the fabric.
OTOH, the BubbleBee lav tape has double sided adhesive and a hole in the center,
"The transparent double-sided tape keeps your microphone solid in place on one side and sticks directly to the skin or to clothes on the other side allowing the microphone to be safely and securely mounted almost anywhere.
The tape also has a small piece cut out in the middle of the tape, which is to be saved and used for fixing.The transparent double-sided tape keeps your microphone solid in place on one side and sticks directly to the skin or to clothes on the other side allowing the microphone to be safely and securely mounted almost anywhere".

Outstanding! My search for Bubblebee did not turn up that info. That product line is just what I'm looking for. Strangely, this is not what I recall seeing recently ... but if anything this is better!

Thanks again, Rick!

Your welcome Greg, glad to help my long time forum buddy.
