was trying to make smabat clone and turned out they sound awful
the drivers are the 130 berry. seems that it needs very specific drivers or the venting on my model sucks.

Spoiler: failedbat

Nice work man. Can you share *.max file? There are several things that you need to consider.
Pressure in front and back of driver need to be balanced to provide a better working environment for driver. This requires a lot of testing
Labyrinth canal has good length but I think overall volume is too big. Nozzle part is also debatable
BTW... I like, DLP print material, it's very nice and has nice feel to the touch, but acoustic characteristics can't be compared with resin and metallic shells.

sure thing. not the best in terms of topology and crap, tho.
that hole was supposed to be for short mmcx (the 4mm diameter iirc)
it was printed with pla resin.

also the fitting isnt the best to me.

looking forward on what youll come up with

a bit better after some eq.
the imaging is still messy, but it kinda has that out of my head feeling.

also the volume is sooo quiet, need to crank up the volume at 100 with my direct laptop.
and those rubber rings are a must.

Elfinear (who I believe is the maker of them 8packs and the 19/21 and 400/500/600 drivers) had the comp ti up for a while, but their prices are a touch high and not a popular store on Ali.

Elfinear did not make the 19-21s. It's Haoyun. They make OEM "Foster" drivers of different varieties, most popularly the big solder 19-21s that were derived from the first driver models of the MX500 ('97 -'03 I think?)

so im checking elfinear store and it seem they reduced the price of several driver (mostly the one that cost double), and i found this
https://www.aliexpress.com/item/100....store_pc_groupList.8148356.22.219e5730WLdGMg

im a bit curious, have anyone tried the 30 ohm version?
and in this link
https://www.aliexpress.com/item/100...o.store_pc_groupList.8148356.6.15a85730qE5BYw
there is this option named 32 ohm berrylium, do you think both driver i mentioned are the same? if there is a lower impedance version of the 600 ohm berrylium, this will be a huge found for me, i really love the 600 berrylium, not as bright as 400 ohm, and not as warm as 500 ohm. sadly im only using sony dap that tend lack in power driving

Sometimes Elfinear produces some custom drivers in small quantities like the green and gold 17ohm Beryllium composite but i never really heard of any 30ohm Bery driver, you should ask the seller directly to be sure.

The only 32ohm Beryllium driver i know is the 19-21 variant you can find here https://www.aliexpress.com/item/1005002765718710.html which is very good but has nothing to do with the 600ohm Papa Bery.

yeah youre right, so elfinear answered that the 32 ohm berylium and the 30 ohm berylium are different, probably the 30 ohm one are the lower version of the papa bery

Awesome! How do they sound?
Btw. did you make the gold cable with 2.5mm plug yourself or did you buy it somewhere?

For the yellow one I changed the plug from 3.5mm to 2.5mm and the yellow/brown cable is made entirely by me. Both buds sound great and I recommend these drivers

The LCP driver is also advertised as 130 ohm, I expect it is the same driver...
Do you have a link for the 32 ohm N52 driver?

Also Ry audio store on AE will make you earbud cable with 2.5mm plug on request for the same price as the 3.5 one. I just ordered one and I expect standard Ry quality.
