Editor’s Note: At CYMBACAVUM, we’re constantly trying to bridge science with the wonderful audio experiences we have. @miceblue takes on an scientist’s curiosity to examine Asius Technologies and 1964Ears’ ADEL — how it functions, the scientific principles behind it, and what it might or might not be.

I wanted to put together all of the videos concerning the production of CIEMs behind-the-scenes (there’s an additional Engadget feature on Westone, but I found the other videos more informative; there’s also an old video with ex-UE/JH lab manager Noy where he talks about the curing process in a pretty detailed fashion, but I can’t seem to find it anymore — if anyone has that link, please do let us know!).
From the videos, it’ll become evident that the basic steps are as follows:
- Receipt and trimming of the ear impressions
- Wax dipping
- Negative impressions from the colloid duplicating gel
- Acrylic pouring and UV shell timing
- Shell trimming and electronics/tube assembly
- QC measurements
- Faceplate production and UV sealing
- Final trimming, buffing, and polishing
- Final check and packaging for shipment
Other steps go into the actual design of new models and readying the production line, such as testing all drivers to be used, experimenting with different types of acrylic pours and mixtures, etc. but for the most part, these details aren’t discussed in the videos. Nevertheless, they should still be pretty revealing.
This is the “original” behind-the-scenes video from UE, from way back in 2009. Nevertheless, it’s pretty complete, and should probably be the first video anyone watches if they’re interested in the CIEM production process.
I picked these companies through multi-faceted criteria of technical superiority, logistical reliability, build quality, art, value, and spectacle — it’s not necessarily about who makes the absolute best-sounding CIEMs — it’s about who pulls it off the best in a whole package, and who will remain a mover and shaker in this industry years from now.
These are my picks (in no particular order): Continue reading Best in the Biz: The Top CIEM Companies in 2013
