I'm not a "real audiophile ", just a guy who tries several IEMs and enjoys non-bassy jazz/folk/60's-70's rock...
When Bob describes an IEM as "emotional" and another as "technical" are those one word descriptions really informative and helpful to y'all? Because to me, I go "huh" and figure that I'm just not an audiophile and not-in-the-know.
'Emotional' describes the rollercoaster feeling you will have as you try to justify the expenditure to your other half
'Technical' refers to the exuses you will invent in order to achieve the goal above
On a (hopefully) more serious and helpful note, I'm a kind of lower mid-level/blue belt in the audiophile world lol.
With time spent in enthusiastic practice, I learned to be able to actually taste and distinguish some of the flavours described in fine wines and coffees.
In the same way, I'm starting now to be able to understand and perceive some of the technical terms that get thrown around here.
I'm still far from being an expert or being at the level of many on here though, so please take my advice with a pinch of salt and listen to what others have to say!
Here's how I have learned to interpret some of the terms (which may be incorrect, but I'm sure others will jump in to kindly inform me if this is the case!)
If you can imagine a graphic equaliser with all the switches in a straight line along the middle, that's kind of what people are getting at when they refer to a 'flat' or 'reference' sound signature.
Now imagine whacking the bass up to 11.
You've just 'coloured' the sound signature. Imagine instead that you'd turned the bass switches up to 3 (above the middle), and done the same with the treble.
Now you've created what is often referred to as a 'V-shaped' sound signature. This kind of sound signature is very common amongst entry and lower level earphones, but can still be found even at much higher tier products, and can lead to what's often described as a 'fun' or 'energetic' sound.
Note that you can have a strongly 'coloured' signature in this way, or sound signature that only mildly deviates from the flat, reference sound (sometimes called a 'shallow V-shaped' signature).
So, going back to the flat EQ, reference sound signature, I'd interpret 'emotional' as meaning a sound that deviates in some ways from the flat, reference sound.
If it can make certain aspects of the music stand out, or make you feel up close or immersed in the performance, then I guess that would be why it's described as emotional.
The 'technical' descriptor, on the other hand, may indicate a more reference/flat tuning, but I actually think it's not so much talking about that, but rather the ability of the earphones to allow you to notice more details in the music. Instruments playing in the background that you may never have noticed before, for example.
So the way I'd interpret 'emotional' and technical' especially in the context of these two earphones, is as follows:
The Icarus is described on their website as offering very good "3D imaging and instrument placement". This would probably allow you to feel comparatively more immersed and involved in the music. Along with a non-reference/flat tuning, I'd imagine these together contribute to create the 'emotional' listening experience described.
I would imagine based on all I've read, that the Master, whilst still probably somewhat v-shaped, offers a *comparatively* more reference/flat sound signature, along with greater levels of detail.
I'd suggest that these would enable you to notice more details and nuances in the music, hence them being described as being more 'technical'.
Note that Trinity's wonderful interchangeable filter system means that you can quite extensively modify whatever sound your earphones come with as their 'default' sound though
Well, that's my interpretation. Feel free all to chime in with your own or to suggest corrections to mine.
Hope it's of some use
