Of course not and this is more common than you think. A lot of sets have imbalance, regardless of price.
Average consumer gets that problem every now and then and probably doesnt know it, so brands get another pass. We now live in times that people say phrases like “it’s only 20 bucks” or “qc gamble”.
Sure, this is a luxurious good, but imagine they were making fire extinguishers

I’m not sure if common = acceptable, and I don’t think just because the avg consumer doesn’t know it makes it ok.

Are people buying boutique IEMs at this price average though? I personally think any IEM at this price, especially from a boutique builder that could thrive or die quickly, shouldn’t be sending out something so imbalanced. They’re not pushing out a lot of volume in comparison to the major suppliers and any negativity could kill them quickly. It would really benefit any builder, especially from a boutique, to just buy a cheap coupler and provide a graph at least showing lack of large imbalances like @VIVIDICI_111 at the time of build completion.

Oh maybe I got misunderstood, but QC/QA is the thing that annoys me the most lol. I dont think it is ok even on a 20usd set.
Edit: oh lol, this is why you dont feed a baby and text at the same time edited original post

Agreed not that hard at factory to spend 2 min to measure up a set.

They spend 30secs and you spend 30 bucks.
Better than spending 20 and throwing it in the bin. I think pre orders and mass marketing is also a problem. Factories are now pushed to have insane amounts of stock Ready everytime they announce something, thanks to “happy meal” prices. Once you get above budget range, I dont have words.
Still waiting for a matched channels penon set, or final audio.

Sidenote - A/Bing the Diva and RSV right now with Vocal only tracks (so there’s no clipping or bass influence/imbalance) and ya, the RSV is still king for me dam 
What a legendary set.
Even though Diva is a noticeable step up in stage, resolution, and layering it just doesn’t hit the same as the RSV. I get goosebumps with the RSV everytime godam. So natural, detailed, and powerful. Diva is more laid back and airy/sharper in note transients, a cleaner Dark Magician with better treble detail if you will, but I find the note-weight and distance on the RSV to be absolutely perfect for vocal only/centric tracks, especially ballads. Rock and other stuff sounds better on the Diva, and ya RSV gain may be too much for some, but it’s perfect for my ears.
@nymz How hard are you kicking yourself selling these to me

I have one sincere question though: we know every manufactured item is build considering some tolerances. What is an “acceptable tolerance” for iems (ie a difference that couldn’t be heard)? 1dB? More? Less? Does it depend on the considered frequency?

1db or less is great, IMO; if someone can keep a FR to within 0.5db or less for the entire range, I doubt that anyone could actually hear it.

Oh man the amount of times I was all over the place when my kids were babies. Between lack of sleep and trying to multi task my conversational skills were a hot mess. Still are today at times but they’ve gotten a lot better.

You have to add a stop at the factory line, where both sets have to be measured by calibrated couplers, and have a person or an automate checking results and acting accordingly.
If the time of your test isn’t short enough, you slow down the whole line.
Then you have to decide what to do with unmatched sets. Do you sort them in the hope a “more matched” side goes out of the line?
So creating a test to check shell matching isn’t as easy as one could think.
It doesn’t cancel the fact that companies should be more careful about QA/QC (for a supplementary cost for the consumer of course). The way I see it, it could even be a marketing argument “our pairs are systematically tested, and here is on paper the FR of YOUR set”. The thing is though the majority of the consumers doesn’t care about all this, so the company aren’t pushed to do it.

It’s not a straight answer, but I’ve tried a couple of IEMs by now, so I’ll give my 2cents on it:
- There’s natural unbalance on your ears, this will make you more subject to the unbalance of the iems or not. In short, this means that everyone hears different and will be affected differently. A good example for this would be using buds in different positions for each ear;
- Tips can affect unbalance, but rarely if they are well built;
- There’s a difference between having an unbalance here and there or across all the FR, with the latter being much more noticeable/worse;
- If you have unbalance in some areas only, they won’t affect you the same. e.g.: I won’t notice sub-bass as much, or treble extension. I will notice a lot on mid-bass and upper-mids. The first make the “impact” sound uneven and the later will mess stage position of the vocalists;
- I do consider differences equal or below 1db acceptable. 0.5db or below are non-existant to my ears.

Not at all, ahah. It was calculated.
Me and a pal sold it at the same time. I got U12T and he got Trio. We still joke to this day that in the end, we will buy another set. It’s a big possibility.
I have like 5 iems or so still on my bucket list, so I gotta take care of hearing those first.
Oh and to everyone that doubts of RSV, I’d take it over 95% of the market, regardless of the price lol

Understood at the lower price point nor would I care. You hit the kilobuck and above or boutique IEMs and they should not assume we don’t care. Your hitting a price point and audience where it should be assumed at this price point we do care. Or if they want to assume we don’t at least provide proof of their craftsmanship and a means to offer some level of protection from potential flack that could blow their way.
