Thanks for the answers! The the Shure bodypacks have a 20KOhm bias resistor to ground where I wrote “BODYPACK_20K_BIAS_AND_AUDIO”. What difference does 100Ohms make? It’s a 0.5% difference,

R1 is to bias the Fet properly. Also there is no 1G resistor as that Fet has an internal diode designed to “leak” current and somewhat act as the 1G resistor. Most electrets with built in FETs

It's sometimes called electrostatic guard. A very common technique in RF and very high impedance circuits. The parasitic capacitance is used profitably to bootstrap the gate. It shields the gate as

When cell phones became common, Shure lavalier microphones were picking up GSM noise. Shure changed their FET circuit, added a dot on the lavs so you'd know they're the new type and marketed them as

Ha! This is some interesting stuff! I didn't know bamboo can be so hard it requires metalworking tools. Great reading, thanks for interesting and extensive information :) Didn't know your pole

I opted for the felt-covered version in the hope that they would be slightly better at rejecting dust etc in the field. Also, they were a few cents cheaper. I recall seeing SONY and other pro lavalier

You are right. Many bamboo species are light. It depends on the type of bamboo. This is a so-called Moso bamboo (Phyllostachys edulis). The pole with the headphone is dry, hollowed and about 5 feet in

Heinz - what a splendid setup! :) Bamboo too heavy?? Seriously? It's empty inside. Or is there something I don't know? Compared to my head it should weight next to nothing :) Mine's probably around 2

Thanks for your kind feedback! I tried something similar with the Victor HM-200 Binaural Microphone Headphone. But it turned out that the bamboo is much too heavy to carry it around. Anyway, it was

Yup! One's portable binaural tree ? BTW your (lovely) bamboo housings prompted me to move my lazy ass and finally make this True Tree Ears version. Beforehand I just fastened home-brewed lavaliers

Vladimir - I also got the same version: no felt, perforated front (from TME in Poland, much lower shipping than from Mouser). Official PUI datasheets of both versions show no differences.

Oh. would you please tell a bit more about 'fun stuff' you mentioned. It is interesting.

So cool! One should start a true binaural forest soundscape project. :-) Which reminds me to continue my bamboo microphone housings. Many thanks for sharing! Heinz

The one gig is pretty much “industry standard”. The capsule capacitance swamps the LF noise it can generate. You could easily go to 2G at 10G you can run into humidity issues and other fun stuff.

It's going to work, but not as good. I have a friend who is an electronics expert who said that even 1G resistor is actually not too good and it is recommended to use even higher value resistor. It

nice inexpensive solution. which aom 5024 version is yours? I've got a pair of 5024 with naked metallic front side with some pinhole perforation on it. I know there is also aom 5024 with felt or

Casey - My wonderful, funny wife thought of this even before I finished putting everything together.

Sounds great! But it's not done until it has a couple of googly eyes (helps with HF dispersion). :-)

I love it! Best Regards, Jules Ryckebusch
