I recently spoke with @FranQL about the custom DIY model with PK2 driver. He asked the Chitty store to put together DIY buds with this combo: a PK2 driver, a PK shell and a "goddess" cable with 2.5mm plug. Chitty store now has this model in stock https://www.aliexpress.com/item/1005002280618982.html

edit: He also ordered the PK1 150 transparent driver in this combination and now he told me that he even ordered a spare pair because he was delighted with the sound quality and the quality of the buds themselves.

I'm a big fan of these open-back metal shells from NSC. Has anyone else given them a try?

They're not cheap (~15USD) but IMO they greatly improve sound quality when compared to MX500 shells. They have a wider soundstage, deeper bass, and pleasant mids and highs. I've messed around with different tuning foams and positioning in the MX500 shells as well as adding different vent hole(s) on the shell, but I'm never really content with the sound. Seems like mids or highs always suffer when trying to boost bass. I probably just have to keep practicing with the tuning... lol. But in the meantime, these open-back shells sound great with minimal tuning. I've got the 32ohm red dot drivers in them and I think I prefer these buds over the 64 ohm Ti composite and 130 ohm Bery in MX500 shells. Also, made my first 4 core cable! That was fun.

Beautiful ! Good job !

@Maceinspace

What a great set you have assembled!

 

[Maceinspace]

@rprodrigues @jeejack thanks! Couldn't have done it without this great thread.

I was wandering about PK2 drivers in different shells.
Has anyone tried these in long docomo shell vs pk docomo shell? Does anyone has impressions about the sound difference?

Beautiful! Are those extra stems that come with the shells used for installing diy cables? If so, could you show how to connect those? Is this shell compatible with generic mmcx cables? Thanks

Long stem docomo shells produce more mids and lows than PK docomo shells.

By the way, have you bought anything interesting in the current sale?

Anyone tried these?

I have bought the titanium 14.8mm 32 Ohm a month ago, but it is still shipping.

Long stem docomo shells produce more mids and lows than PK docomo shells.

I like these long docomo shells more and more. They fit in my ear and don't move a bit. I bought 2 more to try the titanium and biofibre drivers.

Thanks! These are generic mmcx connectors, though the stock connectors would look best. I broke one of the stock mmcx when trying to remove it from a different cable . Here are the connectors I'm currently using. The quality is only decent but they fit the shell's stem width well. I followed this YT video for the cable and mmcx soldering.
I bought another of these shells during the sale so I'll post some pics in a few weeks of the build process! In the meantime, here are some pics of connector and shell tuning.

Small heatshrink tubing to protect from shorts at the soldering site. Aso added a small square of micropore tape to the vent.

Thick horseshoe foam with micropore tap covering the two exposed ports.

Generic mmxc connectors. They're glossier than the stock pair.

Hi folks,

Any idea where I could get the wire used for the following Tin Hifi upgrade cable?
https://pt.aliexpress.com/item/1005001645153926.html

It uses a single wire per side.

Thank you

Actually, it uses a cable with many strands of enameled copper wire. Most earphone cable is the same but the half of the strands are red or green coloured for the right and left positive, and transparent enamel for the ground.

Maybe this one:
