When compared to Aria OG, HOLA has better implementation in dampening.
I’ve clocked 10hours of burn-in on HOLA last night now the initial phase of driver burn-in shall be done.
Just tried with
an acoustic jazz trio track, I still see the 30hz somewhat slow tail of the transient and thought that might be the artifact of stock ear tips’s black silicone material. Switched to H570 and wow….!!!
HOLA is more capable than I initially expected, maybe even better than my modded Aria OG. H570 has great synergy with HOLA as well. The “Air Pressure Balance“ per what Tanchijim called their ear tips APB, is very ideal for HOLA & H570. It gives space for bass transient response to reacts very naturally which ultimately leads to very high grid conformity of sound image and it’s momentum delivery.
I’m not even changing the stock cables at this moment and running HOLA with single end mode, not sure what HOLA would present with balanced output after 30 hours.
It’s already “more than great” line in my expectation level.
An entry level IEM definition may need to be overwritten. At current pace of truthear’s improvement (from very basic level ear tips for ZERO/HEXA, to more modern
fluid dynamics based design), they may come up with H570 like echo camber resonance control silicone material in the next issues.
