The Fourte and Trio have only 3 and 2 BAs (in addition to a DD) each. In these each BA covers only one frequency range. Does it mean that these drivers will be worked harder to get the same volume and as such they are more likely to distort?

No. The drive level is only one factor, but there are a lot of other factors at play as well.

"The price is also higher because high driver counts add to the cost on our end, as well as typically requiring a bit more labor to assemble."
What about Trio and Fourte with only 3 and 4 drivers respectively?

Again, the driver count is only one factor. The Trio and Fourte are priced higher for other reasons.

Thanks everyone for all the great insights. I think I know what I need to look out for looking forward.

I do have one more question that might be a bit random... I've recently been looking into earplugs to be used for going to concerts... something to protect my hearing but still be able to clearly hear and enjoy the music. Could the custom IEMs with an m15 module be used in that function? Thanks!

Absolutely! I’ve brought my customs (sans cable) to a number of metal concerts for that very reason. They work great.

Increasing driver count is typically for two reasons. One is what Matt covered, where multiple drivers output the same frequency, so you get more amplitude without pushing the drivers as hard. Or, you can assign them each different frequencies, have better coverage over the entire range and have finer control over it as well. In the latter, think of the drivers like points or faders on a parametric EQ. The more points you have, the finer control you get over your EQ. So, rather than only having control over the lows and highs in a dual-driver IEM, you can manipulate the lows, mids and highs in a triple-driver. It allows the designer to EQ the IEM more precisely.

The possible decrease in clarity you're talking about may be referring to phasing. When you have drivers outputting different frequencies, there's a possibility that some of the frequencies they're outputting may overlap. For example, where the bass driver ends may slightly overlap with where the mid driver begins. Now, if those frequencies are misaligned in the time domain - meaning, they don't reach your ears at the same time - they may destructively interfere and do funky things like cancel each other out, resulting in an unfocused, often hollow sound. That's what may cause incoherence or unfocused-ness in multi-driver IEMs, but they're so advanced and their designers are so skilled now, that you're very unlikely to see phasing in a renowned brand like 64 Audio.


The Fourte and Trio's drivers are all tubeless, which changes their properties by quite a bit. I wouldn't be surprised if they were able to resolve and perform at a higher ability than most multi-driver designs. So, they don't need the extra headroom that stacking gives. Although they have relatively low driver counts, what drives their costs up is the R&D invested into the acoustics around them. Because they're open drivers, they radiate freely, and you can't tune them like you would a closed, spouted driver. You can add dampers and manipulate the length of sound tubes to shape the frequency curve of a traditional driver, but those options are obviously unavailable for a tubeless driver. The way to tune them would be similar to speakers, where you house them in a calibrated chamber that acoustically boosts wanted frequencies and dampens unwanted ones. The time and money taken to make all that work is what you're paying for when you get the Trio and Fourte, and it's what results in the performance that a lot of people have continuously raved about.

Well explained! I too believe that time and cost of developing Fourte and Trio are the price that we paid for.
Tried them both, and both sounds unique in their own way.

Hi,
does anybody know how to remove the grille mesh in the nozzles?
Thanks

We really don't recommend that you do that. If they need to be changed you can send it in for cleaning, but they need to stay there to protect the Tia driver.

Thanks for the feedback everyone. My favorite cans are the OG Utopias, so it sounds like I may be better off finding the extra coin for the A12t as the descriptions of their sound signature appears to be closer to my preference than the A6t.

Ordered the A12t from Bloom Audio and got my impressions done today.

Let the waiting game begin….

oh that's amazing! Which apex module did you use? did you notice any drops in any particular frequencies that may make the concert-going experience worse?

I’ve used both the M15 and M20, and they didn’t make that much of a difference when used as earplugs, to be honest. I don’t know if I’d say they made anything sound worse. I really dislike overt loudness to begin with, so any attenuation is good attenuation to me.

I'll just leave this here. The most beautiful (and beautiful sounding) 64 Audio IEM I've had the pleasure of owning. Review coming soon.

which iem is that, is it a universal iem

It’s the N8 in custom.

Nio is the universal “counterpart “.

I have been using my Penon PAC480 cable with my Volür for a couple of weeks now. To my ears, it sounds at least equal to the stock cable, if not better! For me, it introduces further clarity, the detail retrieval feels elevated, and the soundstage expands a bit. Happy my Volür is so versatile!

That's a very low bar to cross
This one will scale very well with better cables. Brise cables were my go to for the u12t!

You lucky dog. Boy did you make the right decision. Does everything so well !!

 

[Aetherhole]

I took my A12t on a work trip. I hadn’t used them much in a while, but boy did I really enjoy them again. It’s so nice to have a good seal with no fuss! Owned them for about 2 years or so now and still love the look of them, too.

Which Brise cable did you find to go well with U12t?
