I put the 130 Ohm beryllium drivers in the six-hole wooden shells (the background pair) as my first DIY earbud attempt and liked them so much I decided to try making a cuter version. I think I was pretty successful.

I left two of the vents blocked after painting the shells to keep the bass down a touch and they sound just about perfect to me.

Yeah. You really did!

What about that cable?

Looks really nice!

Can you please share more details about this?

I can, it's from a company that was called yurbud, the sounded terrible, meant for sports had these rubber tips the you put on the buds and they wouldn't fall out, I have the rubbers but rarely use, the yurbud shells are some of my favorite for the 130ohm Beryllium. The shells have a large cavity and give really cool sub bass.
Here's a pic, you can see the shells have a large lip for the rubber covers


The model I have are no longer found, it is a pity, I wanted more shells, i enjoy there sound much more then the mx500

The model I had is Yurbuds Signature ITX-2000
Found after a bit of looking

 

[grooveriders]

Apart from the 600 ohm purple beryllium, which drivers have soundstage as wide? Will be ordering some drivers soon so any input is appreciated.
looking to buy pk1 150ohm red driver, 62 ohm Ti, 400ohm graphene.
Also beside the shell/housing does foam/cotton increase or decrease soundstage and how does it affect sound signature?

Very interesting!

So how do the berylliums sound with the rubber cover? When you’re not using the rubber covers, do you install normal sponge foam covers?

The sound becomes congested, the bass gets boomy, a bit muddy
Soundstage gets much smaller
In general not very positive, the only time I used them was on a pair of monks, the tips added a bass boost but at the expense of the mids

I actually have not used the rubber covers in about a year and a half

I received the headphones for free, gave them to my wife, she hated them, then one day she told me she wanted a better pair of headphones, we whent to a local audio store and she bought grados......

A year later I remembered the shells, pulled them out, added 0.78mm 2 pin and 130ohm beryllium and its my 2nd favourite bud, very detailed, good mids and deep sub bass

Well in general stuffing the housing decreases the bass, I have used a bit in the past but have gotten better results by using paper/foam combinations
In my collection the wides sound would be between my 500ohm in mx500 shells and my 130ohm in my yurbud shells, 130ohm in metal shells with wooden cup

My 400ohm have the best overall sound (not too fatiguing, sweet mids, deep rumbly sub bass and airy highs)
My 64ohm ti ($15-16 dollars version) are my bass head buds
My 600ohm had good sub bass (one of the best) but the highs seemed to me to be too polite so I tuned them for there remarkable mids

There is no dilemma around these models. I completely agree with your comment
I also remember that you have very interesting DIY models for each drive. Yesterday I started the post about "nicknames" for DIY drivers. Based on your personal experience what nickname would you give for let's say 400ohm, 130ohm, and 64ohm Ti.?

 

[robar]

As promised, here are the photos of the panasonic shell @furyossa I put a B40 shell next to it as reference. Comfort is better, plastic is slighty worse but still quite decent. In stock form it only has a little open vent at the top. B40 cover fits.

May suggest "Eight Pack" for the 130 Ohm? I think that is quite distinctive to that model.

I think they really deserve a better nickname. What do you think about that?
Now, 600onm Beryllium. I often call it "Bery" but not only because of Beryllium. It reminds me of Barry White (big ie huge impedance)
OK for the rest of the DIY lineup you decide. This is just the beginning

Thanks for starting this, @furyossa I agree with the idea and your proposals, may I suggest pronouncing it "Barry"? I feel it sounds nicer, and sounds more like a 'name'
What do you think?
We need to come up with a name for 19-21kHz soon! Any suggestions?

This is my old post:

I found two pages selling red film 150Ω pk1 driver on Taobao.
https://item.taobao.com/item.htm?id=572623588063
https://item.taobao.com/item.htm?id=569489997267

However Taobao can only speak Chinese, so even if I used Google Translate, it was very difficult when I was in trouble.

https://www.tokopedia.com/
https://www.bukalapak.com/
https://shopee.co.id/
Searching with the keyword "yuin pk1 150 red film driver" on the above Indonesian website seems to sell it at many stores.
If you can ask a DIY member in Indonesia to purchase for you, this method may be safer.

DIY member in Indonesia here. From those shops, Tokopedia has more reputable stores selling DIY parts. Unfortunately, none of those stores advertising PK1 red film driver have registered any sales of that model. It is a common practice to list a unique item to bring traffic to their store, but when you ask them, they'll say it's out of stock. There is one store that I know have them in stock as of last year, but I think they've run out of it and no longer has it in their page.

Yup. 130ohm has the best abs in the lineup. "Eight Packs" or short "8-Packs" We solved that.
Now about 600ohm. I thought about it too, actually a few more names:
- "Barry White" it would fit nicely just if it had a white lid ie cover
- "Blackberry" will confuse many people and they will think that the phone is in question
- "Blueberry" because of blue shells that I use for this driver but it's irrelevant.
In the end, I decided to use simply the first 4 letters from Beryllium. Also because this is the first beryllium coated DIY we can call it "Papa Bery"
Ok. @Themilkman46290 love 400ohm graphene and @robar is bought all 19-21kHz drivers from the Ali (until recently they were not in stock )
I think it would be fair for them to be "godfathers" and give names to these drivers

Look ok. What do you think if it makes sense to use mmcx with this shells?

 

[vygas]

Hi vigas
last time we spoke about that. I found only Nokia models HS-23, HS-40, and HS-43 in one local shop.
Are you sure that HHD-1 has a 150ohm driver? These are all earphones for old Nokia phones. Some of these not have a 3.5mm plug

Hi, sorry for the late reply, and yes the HDD-1 has the exact same marks, dots, epoxy and red shine through the holes on the driver cover. Though, you could get a HS-23 and have a DIY PK3 driver in your hands . P.S. All those Nokia buds need a re-cable and are pretty easy to open up.

 

[Punslayer]

Yeah. You really did!

What about that cable?

The cable is one I put together with spare A2DC connectors and some wire from the CEMA store on Aliexpress. https://www.aliexpress.com/item/33054896260.html

It's a really light and flexible wire, so I thought it would be good for earbuds. I skipped the splitter to further save weight.

Looks really nice!

Can you please share more details about this?

As the other poster stated they're Yurbuds covers. You can find them on Amazon in a number of colors and sizes. For me they do improve fit a lot, but the sound changes can be unpredictable. Some buds sound quite nice with the covers on, while others get hollow and weird. I really liked these buds initially, but the bass was a little much for me and the covers happened to work very well in this case. On the pink version, blocking two of the vents had a similar effect.
