I recently discussed and plotted the NiceHCK EBX21 signature in comparison to the Rose Technics Maria I & II (here).sorry i have other question there was a lucky bag discount for ebx21 earbud .maybe later similar price will be on sale so i want to ask you which one(pt2021 vs ebx21) will beat other in soundstage wideness ,detail,sepearation,can you give some comparions about ebx21 vs pt2021.
Personally, I find the PT2021 offers better staging and perhaps the type of timbre and imaging that you are after, more than the EBX21, which is still a very good earbud in it's own right. I consider the EBX21 to be an excellent reference option for critical listening... that is if you can handle their bright cold analytical nature. I really liked the EBX21 but sadly it was way too fatiguing and gave me horrendous head/earaches. The PT2021 is far less offensive in these regards.
My recommendation would be to choose the PT2021 in any of it's higher impedances... neither I or ClieOs were able to discern any major difference between any of the higher impedance versions besides perhaps maybe a sliver of more bass extension offered by the ~147Ω model but that was questionable. All the higher impedances scale remarkably well and offer the very same signature which is astounding. One would be hard pressed to discern and identify (readily and repeatedly) the three (3) higher impedances. The PT2021 line is probably the only series of earbuds that I have ever heard that has successfully tuned the same signature across multiple different impedances. Remarkable to say the least!
