Too much upper bass/ lower midrange ("mud"), even more ear gain than the already exaggerated Harman2019 target, distortion peaks and not crazy cheap. A quadruple no for me. Why choose these when there are the Salnotes Zero II and the Truthear Red, besides many others?

Please watch my post from monday.

Ok, maybe you can improve the frequency response a bit with some switch configuration, but this still not makes it competitive to the Salnotes Zero 2, the elevated ear gain does not diminish, the distortion will also not go away by it and the prices stays the same. So?

Neither IEM is perfect. Zero 2 has a shallow TWS like fit that won't work for everyone. The tuning of either set could be equally valid depending of your listening habits and Trio is customizable in that regard. It's silly to be mad that there are options in the budget range.

I am not mad at all, just stating that is is not a very attractive offer and that there exist even quite a bit cheaper options or equally priced ones which are better. Also in distortion measurements. So I considerer it as superfluous, even failed.

Realistically, any product that fulfills basic requirements and is stocked by retailers can't be considered a failure.

One basic requirement for IEMs is achieving a secure fit. Without a secure fit, measured metrics become useless. Fit issues have been reported numerous times for the Zero 2. Any IEM operates at the mercy of the user's anatomical variation, which significantly impacts the FR and comfort. These factors are not reflected by measurements but have a significant impact on an IEM's performance. That's why I can't call the CCA Trio "failed." I don't believe such conclusions are useful.

Besides, the IEM market is an ecosystem that creates an impetus for manufacturers to continually improve, leading to better products over time. To me, it feels irrational to call any product "superfluous" while caring about better IEM performance.

You don't have to agree but this is how I see it.

Just look at the distortion peak. There are so many IEMs with basically zero distortion starting from $15.

Are you saying that in real world use you are going to hear that???? :facepalm:

Do you know how loud and harmful 94 dBSPL is long term? Of course it is good to have headroom for EQ and whatnot, but with these IEMs you are most likely bringing things down. Yes it is possible to do better, but it isn't really a problem here. Certainly not one for a $20 IEM.

Trio appears tuned for low to medium SPL listening, with a lite extra bass and treble resembling a light equal loudness correction curve. 94 SPL or higher is definitely not a normal listening condition even with IEM of a different tuning style. I hate to say this but you always see reactive comments, with absolutes, by those that don't seem to think carefully about the real implications.

Even if your average listening level is well below 94 dBSPL, there are peaks in music which, for a short time, might get much higher. This distortion peak is around 1 kHz, were our hearing is most sensible (in the bass it would be much less relevant). Furthermore, I like headroom and good engineering, not products that are barely ok. Also Amir states the price as $44, not $20.

So why should I choose this IEM, where there are many IEMs on the market with negligible distortion, lower price, better tuning and also from a better company???

OK, I see you are just talking off the cuff and not being serious. Happy holidays.

I have no idea why you are saying such a thing. I provided you arguments and evidence. You provided nothing but condescension.

No more of this thanks .
What? Please look at the original message. When I make a complaint, I am getting told "I need to be less sensitive" and when I say the same thing to the original poster, I get reprimanded ? Where is the logic?

You are a relatively new member that might appear to be trolling more Senior members. Our Senior Members are here to provide technical support and advanced Audio science and engineering knowledge to those that seek it. They get pretty tired and irked if they feel or sense that they are being played or punked. As a new member this is a behavior that you want to avoid at all costs. Because once the members start detecting that you may be here for reasons other than benign and beneficial purposes it won’t be long before the Moderator Team comes to visit. I am giving you the benefit of the doubt here and calmly and politely explaining this to you. Knowing full well that what I just explained is common knowledge at most technical forums. However, if you keep this type of behavior up you will not receive further benefit of the doubt here…. ;)
