I threw caution to the wind and purchased this model, and it was the right thing to do.
Just as I thought, final never lets you down.
It looks like I'll be enjoying a completely different sound than that of FI-BA-SS.
There is latitude in the essential sound, and the sound field is wide.
It's a comfortable sound with a lot of bass, but since separation and resolution are high, there is no stifling. Compared to other single drivers, these sound really three-dimensional. Lingering sound is good, too.
This is just how things feel for me; I don't know whether it's because of the lingering sound and the bass tones, but there are times when it sounds as though the tempo of songs is faster compared to with other products.
Until now, no matter which product I bought, I ended up using FI-BA-SS frequently, but it looks like I'll be using this product frequently.
If there is one flaw with this product, it would be the fit. My left ear canal is larger, and the left and right pieces are different, so it's sometimes hard to find the right fit. With LAB I, how I insert them into my ears differs from left to right; the distance from the eardrum also differs from left to right, and so it's a bit hard to adjust them.
FI-BA-SS has a better fit.
But since these have a sound that makes up for the problem of fit, I recommend them.
To sum these earphones up, I'd say "ultimate naturalness".
These are clearly different to the expansive group of earphones that have a lot of drivers packed into them in the pursuit of resolution and that sound great when you hear them for the first time, but that soon have you tiring of listening to them.
With LAB I, you also feel high resolution and rich bass tones when you first use them, but as you listen, you'll be hooked by the spatial representation, subtle high frequencies and superb, natural overall harmony. They hold a power that has you unable to stop the more you listen.
The beauty of the integrated titanium body, degree of perfection and its sense as a possession are perfect.
I also own some Heaven VIII earphones, and I feel some similarities with these – rich vocals, bass tones and airy feeling – but the overall resolution, richness and spatial representation give a sense of refinement.
