JCally JM04Pro. I am surprised! This thing is nothing like the non pro JA04 version. I daresay I like this JM04Pro better than JM20 and CS-Pro 46L41! What makes this JM04Pro great in my POV is the fact it offered the quality of JM20 minus the sheen and glare to the tone that could make intensive listening session fatiguing. In fact, this JM04Pro is sniffing at Lotoo PAW S1/A&K PEE51 territory with its smoothness and musical expression. Yes, it is not as sparkly as JM20, but this also mean it is not as dry analytical as the former – to me it is a BIG plus!. Yes, I know you may think I have lost my mind, what insanity is this to say a $12 Realtek sniffing S1/PEE51 territory? I am just describing what I hear - I harbour no biasedness towards anything, and I love what I heard. IF this JM04Pro would only offer a bit more sharpness and technical competency, a bit more soundstage width and depth, a little more razor-edged imaging, some more driving power up to 150Ω, I say it would probably equal S1 and PEE51. I will no longer recommend JM20, not after hearing JM04Pro which cost half the price of JM20 now.
PS: Just to make sure I have not lost my sanity yet. A buddy of mine is getting one too, checking if I am making any sense here
OVERALL RATING: 85/100
Recommended Pairing: With anything below 70Ω.
