I was watching a video that shows the Audeze factory, and this caught my attention: the membrane of the CRBN model.

anto22: You should try to build standard e-stat headphones first so you will know what this is about. Than you maybe recognize that the wireless e-stat is no-go. The main thing is that e-stats must be open back design otherwise it doesn't work well. My suggestion is to build standard headphones...

I believe that you must use Eagle from Fusion360 licence. Or it is merged into one program now? You can find lot of guides on Youtube. Free alternative is KiCad, you can do it in every PCB layout program, but it can be sometimes tricky to use it for designing stators and spacers.

mattmatt: FR-4 is from JLCpcb. Mylar is 3um from ebay, but it is few years back I bought it. As for the stretching, I am doing it by hands on flat glass with tape. chinsettawong: Aliexpress sometimes have weird behavior. Anyway, for others or when the link will be dead:

Sure...

After long time I made new E-stats, this time with oval shape. The dimmensions of the cup are 110x90mm. Active area of the diaphragm is 75x55mm. Stators are FR-4 as always, this time 0.6mm thick with ENIG surface. Spacers are also 0.6mm. I tried some graphene nanoparticles treatment for cars...

Does the Uno work with Playstation 5? I did not find this information anywhere. I am considering of buying one for playing on my console. If it works it will be exactly what I am trying to find.

It is open back design. There is comparison with DT770. After all, it was a bit too much with that filter. So I was still working and trying to lower the treble because it was very tiring for longer listening. Small update after some time. Headphones was sent to few people to get some...

Thanks. Yeah, isodynamic is only naming convention, it is classic planar magnetic driver. Isodynamic is this type with bar magnets and orthodynamic is the type wit circle magnets like Final Audio D8000. 5) Progress on the second version I received all necessary parts for new design so I...

Hi All, I have been working on this headphones for some time and I want to share some results. I want to clear from start that I won't give away everything that I learned, mainly not revealing the process of the membrane creating. Although it can be guessed from photos. It just cost me too much...

If it is open back design, then the material of housing will not alter the sound, choose any material which suits you. About how far with the driver, it mainly depends on earpads, generally I would say that deep ear pads will give you better bass, but as the cavity in pad is increasing, it can...

From my experiences I can only advise to you, that you should not focus on such things like materials for housing and ear distance from start. Personally I would try to focus on driver itself, since it is not so easy to create it. When you will have working driver, then you can build some...

Finaly I bought MiniDSP Ears so I was able to do some better measurement of my estats.

Wow, that is impressive work.

Thanks, i quess i will have to try nonagled version then, I found with 110x90mm dimmensions. https://www.aliexpress.com/item/1005003380649489.html?spm=a2g0o.cart.0.0.aad43c00QXLE5W&mp=1

Does anyone have tip where to buy good earpads? I am looking for oval angled sheepskin earpads but I had no luck with finding any. Round types are easy obtainable, but the situation is much worse with oval ones with bigger dimensions.

That is very good price, and it is good that it is working too, I will order one too to try it. I am still using this pair for long time, I've tried tried many different headphones over time but in the end I always ended with them.
