Well just the white filter inside the vent port. It's a small little thing that takes almost nothing to take it out.

But do this only if you feel like u want more sub bass. Reason being is when u take it off, it adds a significant amount of sub bass and warmth, but to me, it's perfect.

well, I already have the serial and the sub bass is decent on that so maybe I will let the Vortex live in peace.

I don't notice much warmth added but my interpretation of warmth may be different than yours. I really want to measure them with the mod because my gut says that it reverses the roll-off that happens around 90Hz and results in a nice bass shelf

Yea maybe not "warmth", but a much larger presence of bass. I can not only hear it, but feel it. And I think you're right with reversing the roll off. I think Penon was going for a specific sound signature with the Vortex when they slapped the filter on there. But they secretly packed in a wonderfully designed vent that could double as a bassheads dream when tinkered with. Haha

So call me crazy.... But I think I made the Vortex sound even better by changing out the nozzle grill. This is what I switched it with:

The sound seems punchier and crisper to my ears. Overall an even more enjoyable experience!

Did you take the dampening filter off that was in the nozzle as well?

No I did not. I left the dampening filter in there. Just swapped out the metal grill.

Thanks all.

Here is my review of the Globe.
https://www.head-fi.org/showcase/pe...ifi-audiophile-iem.25087/reviews#review-29019

Good review. I also found a certain similarity in sound between the Penon Globe and the Sony IER-Z1R.

Well I’m 100% happy with the Vortex but you all know what curiosity does… so I tried the bass mod.

With filter:



Vortex filter, with the needle that I used to remove it, for comparison:



Without filter:



Listening to it as I type and it’s almost as though someone threw a new bass DD in there.

What I’m hearing is a nice thicc slab of sub bass. It rolls into a tasteful mid bass hump and warms up the mids a bit. Upper mids onwards are pretty much untouched as far as I can tell.

It’s funny but this mod makes the Vortex sound more like ye olde classic Penon. The bass, that warm tilt. Just that you get to keep the new, improved treble.

Verdict

Try the bass mod if: you want to use your Vortex for the likes of Chemical Brothers and Massive Attack, or if you simply want to feel some sub bass. Or if you miss classic Penon tuning.

Maybe think twice if: you listen mostly to acoustic instruments and love the texture and detail in stock Vortex bass. I will say that this was one of the things that gave Vortex its special sauce.

So I have a foot in both camps but will listen for a few more days and tip- and cable-roll a bit before deciding whether or not to put the filters back.

So nice to hear a parallel view on the subject. I just went with the idea after the Globe was insistent.............asking me to pull the IER out.......surprisingly they did share a couple tuning similarities?

So glad you liked the mod as much as I did! What I found tho was that you need a pure silver cable to somewhat tame that bass. Even then it's still pretty bassy. But I love it

Also I use Azla lite tips. That's a great combination I feel with this mod.

Which penon iem is Vortex without the filters most similar to?

Another shameless plug, Vortex on offer for EU only if anyone interested!
