Can you currently get sonion E25 or E50 anywhere? Did they stop making them?

Edit: adding random thought: anyone used gutted TWS shells for wired projects? Lots of room in there for BA's...

Only one guy in the world sell E25. Check yoycart shop.

Re-did the CI-30120 brass tube measurements because they weren't sitting right in my head. Turns out I must have had a leak before on my driver inside zobel tests, with the big volume difference in the low end. Here is 0.6mm ID vs 0.2mm ID, both tubes about 25mm long and this time I made sure they were sealed well with tack.

Looks like a nice cheap and easy physical low pass solution for solid subbass with good rolloff to 1k and up. Not to get my hopes up too much, but that curve looks strikingly similar to a sonion 38d1xj007, for about 10% of the cost. Surely won't sound as good, but on paper...

Bonus, it will be extremely easy to package inside a nozzle, this 0.2mm ID 0.6mm OD tube is TINY. So as long as you have shell room to fit the driver itself, should be good to go.

Comparison curve, and 0.2mm ID tube pictured. You are looking at the thin side of the CI, other side is about 3x as wide.

I have 26-E25WT02/9, do you want to buy it?

I think the person was asking about the E25ST001/D, E25ST002/D, and/or the E50DT0005/D.

Only the tweeter part
Otherwise he might have to disassemble the driver

 

[Wgibson]

Yeah, thanks but looking for just the tweeter. And I live in the US so depending on price, it may not make sense to try to ship to me. Really they just look a little better than a 30095 so I was interested, but I have some 30095's ill try out first.

I looked up the datasheet and those seem like a good full range solution by themselves, maybe you just try to make a small earbud style, use foam or mesh filter on the nozzle if needed.

Hi all, after take impression out of silicone mold, the paraffin which I use to coat on impression is broken and stuck inside mold. Any one are same issue and how to solve it?

 

[Bassiklee]

Blow it out with compressed air, carefully pick it out with tweezers.

Hello team
does anyone tried made some diy ATM earphones?
like "Project Heaven" on AMT driver (Air Motion Transformer technology)?

@dhruvmeena96 i'm getting a pair of these soon, traded for them, altho they can be purchased for around 1.3k euro iirc.

edit - the hybrid ones, dd/amt black/gold pair.

 

[BigBublik]

I want to make hybrid CIEM.
I like sound in my GK-31732 but i have more bass and more textured bass. I think use TWFK for tweeter and dynamic driver for woofer.
And i have some questions:
1. Crossover. Which i need to use?
2. Driver. I want to buy Sony MH755 or MH750 and extract dynamic driver. Or are there better options?

 

[Wgibson]

General question, which do you finalize first? Assuming you're happy with circuit design and preliminary frequency response measurements.

Do you finalize physical stuff like attaching and gluing tubing, dampers, verify fit in shell.

Or do you do all the wiring first? And risk having to rework or damaging something as you try to get it packed in a shell after it is wired?
