what exactly did you mean by that?

Looks like the days of my ER4S pair are numbered. Both barrels are showing tiny cracks on the nozzle area. Might be due to age or the infamous Knowles filter issue. Any idea that might help to save Ety? Superglue?

Again that yellow stuff. Where do they get it, I wonder...

Question for fellow ER4S (not P, SR, XR) users. Do you hear sub-bass rumble at the start of this video which lasts about 10 seconds? Neurotech - When the Night Falls

@EtyDave I suppose, acoustic dampers are matched in Etymotic iems as well? It seems Knowles dampers come in different sizes. Do you know the size for ER4?

Mine is old gen with plastic body. Thank you for advice. I don't really understand this part. Would you be so kind to explain?

Maybe it's placebo but somehow plastic green filters paired with ER4 result in different sound vs Knowles acoustic dampers. Does anyone know where genuine Knowles dampers can be purchased?

And the reason for that is? Also, according to service manual it's not a good idea to open up 700's until absolutely necessary: "More than 30 minutes's exposure of a high polymer diaphragm used in the SE-700 will affect its property, resulting in impairing the tone quality. Also never touch...

Yep, it really was an old filter that messed up balance and projection of sounds.

Even though it looks clean with magnifying glass?

Experiencing weird behavior with my ER4. Feels like balance has shifted slightly towards the right side, and sometimes most sounds come from this earpiece. Everything was "centered" before. Does anyone have a clue what that might be? New eartips didn't work. I haven't tried to change the...

He did that 7 years ago.

Depends on what you prefer. RS1 is heavily colored pair of headphones.

Does anybody have a clue what's going with Etymotic ER38-15SM standard frosted eartips? Is it out of production?

It's not. If you don't know how to read graphs - don't read it🤷‍♂️

Considering all the tweaks you did with it I would say K340 is a very poorly designed headphones :relaxed: I certainly would not tinker with headphones without measurement gear and necessary knowledge for all the stuff, but that's just me. Seems like it works for you just fine. In my opinion...

Final Audio D8000 Depends on what model you're comparing to. Although I'd heard PM-3 a long time ago, I would say it has a "cleaner" sound overall, free of that common "haze" among vintage. PM-1 is a whole different beast, much better than aforementioned.

Optimize? What are you hoping to optimize there after AKGs engineers without proper knowledge in the field?

I beg to differ, but OK. Everyone should form their own opinion based on experience.

Nah, just a normal routine for an Ety fan. After all, tips do get softer with time. Now the real challenge comes with a fresh out-of-the box frosted triple flanges. Putting them dry can make cry even a grown-up man:sweat_smile:

So, anybody got a chance to try it and compare with other Centrance products in regards to pure SQ playback?

Would you be so kind to post those impressions here in the thread?

That's what happens when people don't look at the etymology of those words first.
