I agree. Spacious sound is better than closed in.
It doesn’t have to mean it’s better, it’s my personal preference. But that doesn’t mean I don’t like the intimate sound, after all, it depends a lot on the mood.
Nowadays, modern music makes a lot of use of artificial sound and effects, whether it is instruments or vocals. For that music spacious sound is better IMO
For quality records, natural sounds, live music, etc., both (spacious or closed in) can raise the mood to a special level, to the level of pure enjoyment,
and I hope that's why we love this hobby.
I find that the larger single vent newer PK style shells sound more open, due to larger internal volume. They just require waaaaay more work to fit the drivers.
Two things that are of great importance for the natural movement of the diaphragm and depend on the internal design of the shell are the pressure release and the reflection of the sound wave. The pressure release can be similar whether they are in question MX500, PK, DP100, metal shells because it depends on the total size of all ports.
What makes them different is the way the sound is reflected and its return speed. The size and shape of the cavity are "responsible" for this,
but also tuning filters and cable, which act as diffusers and absorbers.
That's part of the reason why the 'bell' shaped K's earbuds sound so good too probably.
I didn't like the sound of the original K's Bell-LB due to the anemic bass. Someone recently mentioned that there is a new "2020 edition". Is this a new model or it's the same model? Is there any difference in SQ?
