we have. Anytime we increase or reduce the amount of pressure relief it mainly makes changes in the bottom end. Interestingly, because of psychoacoustics it changes our perceptions of the whole frequency spectrum. -more HF "sizzle" -good enough bass response to listen to more modern music, for...

Love the review. Just to confirm, the faceplates are actual copper. They are coated to protect the copper and keep it from continuing to age.

Hi, thanks for your question, the Universal IEMs ship with our leather case which doesn't have that accessory insert. The universal IEMs also do not include the clip and cleaning tool. If you scroll all the way to the bottom of the product page, we outline everything that should come in your package

Hello, thanks for bringing this up. To correct the record on the foam insert in question it was always meant to be a temporary piece that the customer would toss after receiving the IEMs, mostly used for initial presentation. The problem we encountered was that the glue, used to secure the two...

Hi, sorry to hear that the A18s is giving you trouble. Can you reach out to support@64audio.com to get that tested and repaired, it is most likely under warranty since the product is so new.

You're referring to the U12t and U18t compared to the A18t and A12t demo? The Universal demo and retail units are the same

On the topic of cases that fit multiple IEMs, pick and pull foam can really go a long way.

Interesting, I actually just did this after seeing your picture to some tips, and it is an interesting fit.

I believe that is just the Pelican 1150 with the bottom foam piece removed to fit those cases. We showed that in the video mainly to display the convenience of the G10 case. I would definitely recommend the 1150 if you want something of that size.

It does fit the larger Silver Premium Cable as well as a Dragonfly Red

Probably not the G10, but definitely the G40 you just wouldn't have the custom foam for the G40. Maybe a multi-IEM case is something for us to look into.

We aren't asserting that anyone is measuring our IEMs incorrectly. We know that we measure our products correctly in our lab and this is where we make the design choices that were made when making the custom IEMs and the universal demo IEMs. We do stand by our custom IEMs and the accurate...

is there a particular brand of hybrid ear tips that you're referring to? We'd love to give them a try.

I don't recall the video you're remembering here. Can you send a link?

The pelican case does fit IEMs with the Silver Premium Cable

We would probably not agree with the statement that our customs measure significantly differently than the Universal demo. There are definitely outliers, QC failures that go un-detected, component failures etc; but as a general statement that is not accurate. It is the reason we have a...

Another thing to consider is that the ear canal is a natural harmonic resonator as sound comes in from the outer ear and passes through the canal to your hearing system, the reflections caused by the walls of the ear canal sound more natural to the listener, so when building a custom IEM we...

Our Universal demo IEMs are built to sound like the custom versions of those IEMs. Since the universal fitting demo unit sit further out of the ear canal they have to be tuned slightly different to accurately represent the way the custom IEM will sound when it sits further in the ear. They are...

The Pelican G40 case seems to be large enough to fit a couple sets of IEMs

Hi, we're not quite sure what you mean by this question? Are you saying you bought an A18s demo unit from somebody and then got it fitted into a custom shell? Or are you saying that you bought a custom A18s from another user, had it remolded and are needing service? The answer to both would...

Great question, the Universal IEMs ship with our Leather case.

Definitely the most ideal tool for cleaning any type of IEM. One hidden feature is it also can suck the lint out of your phone charging/headphone port :)

Definitely more news to come soon. Expect the unexpected :)

Hi, you should have a cleaning tool provided in the packaging that you can use to brush wax off, and use the metallic side to scrape then brush.
