Hi kennjava Thank you for your answer and the story about your binaural experiments! I sometimes record from vinyl and listen to cassette tapes in the car quite often. I have some cassettes that

Hi Heinz. Thanks for the follow-up, the pictures, and the link to the binaural review. I didn't realize that the HM-200 incorporated a sort of pinnae or directional body shape. Interesting. Yes,

Many thanks for your replies and your interest in this topic. Because of the discovery of Johan (I don't perceive the typical hole in the middle…) I would like to follow up a little. I think it's

Dear Heinz, One more thing...Wind is a nightmare, more sensitive capsules means more wind sensitivity. Wind-shields could help but may dump clearness. Good luck with your experiments.

Thanks for the kind words Heinz. Your recordings and the info triggered my interest in (semi) binaural recordings again. I did experiments 15 years ago with some Aevox Audio mics - a brand I rand for

Andrzej is wise, and if tho HM-200 still works properly, and? keeping it in?its original condition is important to you, then yeah, leave it alone.... If they were mine, though, would open them up

Many thanks for the information. You're right. I'm missing the foam windshields. I'll try building new ones. The Victor HM-200 on eBay seems to be way overpriced. There's one on Yahoo Auction in Japan

It appears this device is also known as the JVC HM-200e. more info on this site: https://www.audiovintage.fr/leforum/viewtopic.php?t=40732 I don't know if your specimen has the foam windsceens, that

Many thanks for your opinions. I really appreciate your thoughts! Last year I read a lot about the World Soundscape Project ( https://www.sfu.ca/sonic-studio-webdav/WSP/index.html ) , Soundwalking

Dear Heinz, Listen to the timid advice of the old "fixer". If something is old and works well, it is best not to disassemble it... Your recording is great, I would like to have headphones like

I've opened up a few headphones lately. kennjava's advice is good. I imagine those HM-200s have an inner and outer plastic piece (aka housing/shell) that are held together by two screws. My recent

I have not worked on that model, but headphones like that usually follow the same general construction. The soft earpads have a rim or flange that fits into a slot that runs around the cup edge.

I listened to the ducks but on loudspeakers. I don't perceive the typical hole in the middle from real binaural. I like that fact. Hope I cross this headphone somewhere to do further

I bought vintage binaural headphones from Victor last year. It's from 1976 and still works. If anyone is interested, I have placed the specs and a test recording in the Victor HM-200 folder (

I have placed the order but it will take some time for the items to arrive.?Until then, I'll think about a possible Sound Sleuth bamboo housing design.?Perhaps a bamboo SASS design would be an

Half of LNprimer.pdf in my Files is dedicated to RFI/EMI suppression. RFI is usually due to some internal circuitry demodulating the RF.? You need to get the yucky RF that is coming in to a low

Hi folks, Groups.io is doing a "reverification" of some (just a few, I think) members as part of keeping spam at bay.? It's legit, be careful as always but this particular thing is

Replaced the tantalum cap and the mic is working once again!

Hi everyone, does anyone know if the Ambi-Alice (GoPro mount version) will fit inside the Rycote "Baby Ball Gag" windshield? ( https://rycote.com/25mm-bbg-windshield-ryc011003/ ) They make them to fit
