120 ohm swd2, fluff compared to them..

Ohhhh.

Yeah, I would hope a TOTL bud would be better.

in fairness, I note that the sound of beryllium drivers is very original and does not look like something else ... maybe Fiio em5, but I have not heard them yet

15.4mm 130 ohm - great speakers. but from a smartphone (snapdragon, kirin processors) - they sound bad. from zishan 2, strongly modded - acceptable. with amplifier Lee Hood 1969 - sounds better.

I just received my package from China with one of the new titanium drivers ordered from NSC audio store, which is this one:

https://a.aliexpress.com/_B0o3rJ

it is a 120db 64 ohm unit.

but instead of that i found this one:

https://a.aliexpress.com/_B0VIoz

which has identical diaphragm picture but is rated 114db 64ohm and has unfortunately a metal cover that I really don't like. Apparently it's still a very good driver and maybe it's even the same, so I don't know what should I do about that.
Any advice or experience with the store?

I've had good luck working with NSC thus far. I would take a picture of them with a multi meter showing the wrong ones were received and see if they can send the correct ones.

I will ask them for sure, but it could be that they are the same driver? It seems a bit weird to me, but the pictures are identical, only the enclosure changes from a plastic to a metal mesh one, and the stated sensitivity.
I wondered what do you think about this. Maybe it's un updated model? It would still seem quite unusual, but I wanted to hear your opinion before asking to the store.

 

[assassin10000]

Someone else will have to chime in. I don't know much about the 15.4.mm drivers available.

 

[assassin10000]

Went back and did a little more fine tuning on the 14.8mm PK1 150Ω red film. The sub-bass extension on these drivers is really good.


Currently on the blue line.


Need to make another couple pairs of shells and re-do the 64Ω N55 and 40Ω Ti drivers.

Seems to me that is exactly the same driver 65.4ohm (120dB). The titles on Ali are always messed up.

Anyone tried Smabat M2 Pro with ST10s Gold driver in them?
Would be pretty cheap way of getting ST10s like sound for about half the price using DIY kit...

Has anyone assembled headphones with 400 ohm graphene speakers? How do they compare to beryllium130 ohm headphones?

At the top of the thread there is a search bar, if you enter "400ohm" you will be surprised to find that the 400ohm graphene is well spoken of and mentioned fairly often

ок.

And the difference in price, in this case, is justified. IMHO 400ohm is a better driver overall. Same as 500ohm and even 600ohm

Went and re-did the 64Ω N55 driver tuning as well. They sound really good, even with lower powered sources like my BT20S (or my older phones).

Going from about 7-8db pinna gain to about 10db definitely brings a slight increase in clarity without being sibilant or harsh. The treble is up across the board and brings details a little more forward but no so far as to be fatiguing or bright.


Here they are vs the 120Ω beryllium drivers. Kind of normalized them for comparison purposes (at about 800hz).
