I've updated the model with a bass port here

That would be great! Also depending on your slicer you might be able to just add a hole for the bass port.

The model is done, I just haven't gotten around to uploading it yet. There are also a bunch of other potential improvements that I want to test out. I'll also add that I haven't had the chance to test print the model yet (my printer's packed up ready for a house move) so I can't guarantee quality.

If you want MX500, I modeled one here. Or you could try the Val39 which is s good copy of the Qian39.

I made a model of the MX-500 shell for 3D printing (link)

Wait until you find out how thin the wires inside IEMs are.

That makes sense. The FF3 don't have the greastest quality bass even if they are fun. Interesting, in all of the discussion around the FF3 I don't think I saw anyone compare the two. I have the M4 and M5 with the ST-10S drivers and they were nowhere near the FF3, but that maybe due to the...

Can you explain what you mean by 'great levels' of bass? The FF3 are already the bassiest earbuds you can buy by far.

On second thought I was probably thinking of the MMCX version:laughing: Luckily it looks pretty easy to 3D print a copy. Do you still have the shell to take some measurements from? It looks like you're right, they're similar but slightly different. Although the sensitivity isn't necessarily a...

Has anyone tried to DIY a Yinman? Identical wooden shells are available on Ali and I think(?) the drivers are too. (600Ω Beryllium)

Having had multiple TRN BT** devices, I can't recommend them to anyone planning on using them out and about. The modular earhook uses a 2-pin connection that's prone to falling out, leading to me eventually losing one of the modules in a dark street. If they eventually redesign the hook to use...

If you're OK with using MMCX-to-QDC adaptors, there's a pretty decent Ety clone on Aliexpress: https://www.aliexpress.com/item/1005003712610618.html

I wish there was more discussion, but I suppose you'd have to try and find reviews to get a feel about which ones are best. Personally I've seen these praised a lot: Tanchjim One/Darling, Etymotic (all of them), JVC FD01/FDx1, Sony XBA-N3, Final E5000, HifiMan RE800

Because 'better' and 'worse' are subjective. If burn-in actually affected the sound of an IEM then surely some people would find it better, but some people would find it worse. After all, we all hear differently right? So it's curious that burn-in only ever seems to make IEMs sound 'better'.

Added: KBEAR KW1 Spirit Torino Twin Pulse Beryllium I think the KBEAR Neon might be discontinued but I'll leave it on the list for now.

I've done it a couple of times. It takes some patience, a sharp blade or scissors, and some pliers or tweezers, but it's not too difficult.

I haven't tried most of the IEMs on the list, but going from memory the Droplet was quite well reviewed and has a USB-C cable. Otherwise, you're quite limited, sorry.

You can always check out the thread in my signature. There's not a whole lot of discussion but I do maintain the list to be fairly up-to-date.

I'm pretty sure Fengru is just the Chinese word for 'DIY'. It's not a brand or anything.

Not just limited to classical either. It's not uncommon for two or more songs on an album of any genre to 'flow' from one track to the next.

That's the one, and as far as I know there's only one 130Bery so find whichever shop has it the cheapest and order from there. It's fairly easy to drive, takes a bit more power than average but no issues driven from a dongle.

My favourite is the 130bery. To my ear it's a better 150BG, but it's twice as expensive.

PETG. Probably gonna go through a few revisions to get the right clamp force. There's gonna be a strap as well which will might be TPU but I'm gonna see if a thin PETG print might be flexible enough. :thinking: If I can do all of the parts in a single print it will be a huge plus.

Folding headband WIP. Going for an ultimate compact headphone.

Just looked this up and it's kind of baffling. Partly because it's a Bluetooth set that's open-back, but also their choice of tuning. They compare their FR with a $1,500 'Audiophile Favourite' and a $50,000 model (HE-1?): I'm not as familiar with what headphone FR should look like, but are...
