I'm filling both vent holes with epoxy (to seal them),
Epoxy is too messy imo. I usually just use gel super-glue, fast and clean.
...then drilling new vent holes right next to the original holes (then I wont have to deal with the tuning mesh at all). I can control the hole sizes with micro drill bits (which you can find on Aliexpress). The drill bit method is precise, consistent, and repeatable.
The drill bit sets are only $2-$3usd (for a set of 10 assorted bits). Plus they're made of tungsten steel, so they will last a very long time (especially with plastic IEM shells). As far as sizes, they're available in extremely small sizes and in very small increments (ie 0.1mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, etc.
While It is good and more reliable method, I think it is still quite dangerous and You need to drill with very slow rpm holding shell upside-down to avoid plastic residue getting into membrane chamber. I`ve done it but prefer fine-tuning port hole with fabrics and other materials.
I have made special needle pins and use thin sticky-paper into what I poke holes - gives me faster and easier method to test out different configurations and driver tunebility potential. After that, I usually go for wood - some bits CNC, some bits pure handwork :wink:
It's all @CoiL's fault - he got me started down the rabbit hole of modding insanity LOL
Sorry for that!

Btw, will try to finish my best sounding IEM ZS5v1 mod this week.

Well, honestly I use UV activated glue (LazerBond), which is far easier, faster, and superior to every other adhesive I’ve ever tried.

Ah, no worries; danger is my middle name lol

Oh, I thought You were talking about some epoxy resin that You need to mix and work fast (messy). I use wurth gel-superglue in 20g tube which is quite cheap compared to 6g tube which costs about 2/3 of bigger 20g tube. I have about 20-30sec time to calmly use it and it dries with about 30sec. For me easiest and cheapest way but each to his own tricks :wink:

The 2nd best audio deal of the millennium was the UiiSii CM5 for $8.99 (I'm starting to sound like a broken record with the CM5 lol). If you like the EDR2's sound, you'll LOVE the CM5.

I ran across these on e-earphone Japan, selling for the equivalent of $50 USD:

Wow, $50! That's quite a markup from the UiiSii CM5!

Shelly HR-5000, eh? Interesting name. They do look like a shell (or a 'bunch of bananas in your ear' as another member pointed out) :)

I have received my first batch on chi-fi iems including QKZ DM1, DM9, DM7, Plextone X41M and UiiSii C100.
Having had a bit of a listen through all of them with some Pink Floyd, Dire Straits, Boccelli, Josh Groban and Daft Punk, the best bang for the buck seems to be the UiiSii C100s. They were the cheapest at under $3 USD as well.
There isnt too much to them, really basic build, but sound great and I am able to sleep with them in as well.
Looking forward to receiving the rest of my orders.

Welcome to the club, glad you like them :)

If you want a little more towards the neutral side get the EDR2. Otherwise, if you're happy with the EDR1 (especially the sub bass), stick with another EDR1 as a backup pair before they're all gone forever and become myth and legend like the ZS1 v1.

I'm in agreement - $4 and change is the audio deal of the millennium!

What's the difference between CM5 and Blitzwolf though? Since both are graphene.
