This is a common thought that I see reflected on a regular basis. The core concept is that music should be about what we
feel - the emotional experience, and audiophile terminology is too analytical and distant from the music. Now if you wouldn't mind, let me defend the 'reviewer perspective' and explain why this reasoning does not work, and we in fact should stick to the audiophile terminology as much and precisely as possible.
Music is a deeply emotional experience when done right: the music of your preference, and the proper gear to let that music shine. But as we see from that sentence, both the music of preference and proper gear for that are highly subjective, and there will be as much variation in both music styles and gear, as there are people to hear it. So, the chance that a piece of equipment can convey the same emotional experience for one person as the next, is in fact more unlikely than it is probable. Someone that listens to classical or jazz music will value very different sonic properties as someone listening to dance, metal or hip hop. A 'perfect' iem for one genre, will probably be more of a specialist than an allrounder also suitable for the others.
So, if I were to write a review that focuses on how an iem is able to move me, what kind of emotional experience it creates for me - would that be a better review than describing its frequency distribution, soundstage, transparency and resolution? It would be a good read, and very enthusiastic, but it would be heavily biased. People might think they can relate better to it, but this only holds up if you listen to the same music with the same style of listening. More importantly, what one person describes as 'great mids' or 'high resolution' depends on what their experience so far has been. That's why we see a lot of reviews on head fi that hype an iem immensely since it is their first TOTL iem. I was guilty of this myself, so I know. Everything just seems perfect when you're making that first step up. But when somebody else with more or different experiences hears it, it might be a letdown.
However, if we both speak the same language, and I am able to accurately and objectively describe the way the music is presented, then this allows the reader to infer if that iem will match their preference and accordingly recreate that personal emotional experience. In fact, I would argue this is the only way that people with very different different tastes, experiences and expectations can gain valuable information from the same review.
So, this why I would advocate the opposite; people need to use and understand terms like transparency, resolution, separation, treble extension, etc, way more. I only very rarely read reviews that give me an accurate picture of how sound will be conveyed, because people tend to just write 'the mids are great'
Focusing on personal experience will not improve this
