Wow, I had no idea. No wonder they were so cheap

Does anyone have any alternate sources for BS6 drivers (Bellsing 10013) other than the Soundlink store on Aliexpress? They seem to be out of stock

  Uneven curing is probably because of uneven light exposure - smaller cups will help a bit to some extent, but it will greatly help to rotate the molds as you cure it under UV light. What I do is rotate the mold 90 degrees 8 times over the course of the curing time period (if my cure time is 8...

@Shilohsjustice , what tubing lengths did you use for your Savant clone?

  Looks interesting! The biggest concern is whether it's transparent to UV light but hopefully it'll work out. It'll be much cheaper too.   Keep us posted!

  The original seems to have been made private by the poster...    Is cutting the tubes and gluing it over the top and side of the drivers the way that Noble did it? Such a massive risk of sealing the outlet port...

I'm planning my next set of IEMs and I wanted to emulate the setup on the Noble Savants so I got myself a pair of ED-30761s from AliExpress. The issue is that the drivers don't have ports on them! They have small slits where (presumably) the sound comes out but no cylindrical nozzles to connect...

  Yea I found that Fotoplast is actually cheaper by volume than the UV nail gel I was working with (Gelaze).

  What material is your mold made of? What nail light and "black light bulb" are you using?

If the pads have come off the driver, the driver is absolutely unusable. 

Anyone know how long silicone ear impressions are good for? I've heard mixed reports of them changing shape over time.

  Nice! They look great!   It depends on how your UV lamp is set up - if possible, it may help to note where the shells are thinnest and try to apply extra light/time to these areas on the next set of shells with something similar to a flashlight. If you're using a UV box, keeping constant...

  They look fantastic!   I tried reinserting mine back into my ears and it was also a struggle and a bit painful (and they were made at an audiologist's office). The portion of the ear canal past the second bend is highly sensitive to anything that touches the ear wall - hence why CIEMs don't...

I just found something fantastic for shell-making:   CND Color Additives       I think that using these in combination with the existing clear UV acrylic we all use (Dreve Fotoplast, Egger UV, UV nail gel) could yield some really interesting results. Using these additives could result in...

HOLY COW @piotrus-g the new crossover works wonders. Everything has a realistic timbre to it now - the snare especially sounds much more natural. The soundstage has expanded greatly now and there's a lot more air. The bass has been pulled back, but still has great impact and texture while...

  I see. I just ordered the parts and I'll try out the new crossover. The mids just don't sound right in the first design. Also, I learned my lesson and bought through-hole components rather than trying to squeeze SMD components in a non-SMD application... soldering them was a nightmare. :P  ...

Yeah, I've discovered the heavy bass of the first design LOL   I ended up using decently high resistor values - 82 ohms on both CI drivers, with a 2.2 uF cap on the TWFK and a 22 uF cap on the filtered CI. This yields a cutoff point for the filtered CI of about 88 Hz, which makes it pretty...

I'm in the middle of ordering the components - I'm planning on using a 10 ohm pot + 30 ohm resistor to be able to freely adjust the crossover point for the filtered CI.   Is there a capacitor type that lends itself well for audio applications? I heard tantalums being thrown around this thread...

  I see - I think my mistake was pouring out the uncured material and immediately pouring in the glycerin for the post-cure. I thought the idea was to avoid exposing the resin to the air and so any leftover resin left in the shell when i poured in the glycerin floated around and caused a big...

  Yup! I took the cables from an old pair of Shures that I had and didn't want to invest in another set of cables, so I used MMCX connectors. They seem to be more durable than the two-pin connectors anyways.    I did separate the TWFK from the GK - it was a matter of sliding a razor blade...

I've had a ton of soldering experience so I'm pretty comfortable with it. My ears and ear canals are small, though, so a design with less components would be appreciated. :) Digikey/mouser are pretty accessible for me (USA) so anything available on there should be fair game. I'm aiming for a...

I just finished making my first CIEM - a quad-driver with a Knowles GK with an extra Knowles CI-22955 connected in parallel with the GK's CI driver. Both CIs are glued to each other and a single 20mm #12 tube was used for them, along with a red Knowles damper. The TWFK is positioned closer to...

Just got these, and found that decored Shure Olives inserted backwards (tapered end facing away from your ear canal) on the nozzles don't affect the sound signature much (read: mids and highs still clear as glass) while still providing more isolation.   Isolation with the decored and reversed...

Hi all,   I tried this mod out and it works really well. I ordered the David Clark gel pads from eBay with the same part number as the link in the first post.   When I first got them and tried to put it on, it was an EXTREMELY. TIGHT. FIT. I really don't want to take them off again. They...
