This here is actually really important: if you like what you hear then that‘s great! Others not liking something should not necessarily impact ones own enjoyment after all.
I greatly appreciate people being honest though. I have no doubt that DMS genuinely doesn’t like the Peacock. And most importantly, he gives reasoning as to why that is. Being critical is often confused with being rude.
I had a similar experience with the Sennheiser IE300. I personally do not like that IEM at all and returned mine. Too dark to me, too little energy, not what I enjoy. I still think though that it‘s a great IEM for those who enjoy that kind of signature, since it has the technicalities to back up it‘s asking price. And it‘s hella comfortable. So while I do not like them at all, I can still acknowledge that it‘s a good pair of IEMs. My experience with the Mangird Tea has been the same: not what I like, but it is a good IEM when I remove what I may find enjoyable and be critical about it.
If they were just not DMS cup of tea he would have said so, and brought up positive points. But since he didn’t I believe he just did not find anything good about these.
Like I said: That doesn’t mean YOU or anyone else might not enjoy them. Your mileage may vary. That sentence is so important in this hobby.
People in general have a hard time accepting differing opinions, not just in this hobby.
Your own genuine feelings and opinions are valid.
Others genuine feelings and opinions are valid as well.
Just because someone else does not like something doesn’t mean that you have to not like it as well.
Likewise, your opinions and feelings aren’t facts and the „end-all“ that everyone has to abide by.
I wish for more quality discourse and a respectful treatment, not just in this hobby.
Discuss, debate. Call out weak points or arguments. Make quality arguments as well. But don’t question someone’s tastes.
Lastly, the best critic is one self. So if you can, Test listen. It‘s not always possible, but when it is, it‘s the best way to try if you like something.
