LISTENING EQUIPMENT USED IMPARTED HUGE INFLUENCE TO SOUND IMPRESSIONS & RATING

TTGK App clearly revealed that JA3 is in fact JM6 in a different package

💚PROS

Clean neutral and natural timbre
Great coherent dynamics
Great Treble textures and extensions with polished smooth decays
Strong Mid-Bass responses, richly textured density and decays
Neutral Mids slightly intimate, richly textured and smooth.
Mild Sub-Bass with smooth decays
Crisp details retrieval, highly transparent
Realistic toned guitars, cello, percussions, and piano
Great speed and transients handling, amazing dexterity
Properly sized soundstage, commendably holographic spatial imaging
Clean separation of layers with precise placement
Great synergy with many type of IEMs/HPs/Earbuds
Great on poor quality recordings and Lo-Fi music despite being very transparent
Great sibilance resistance all the time
Clean black background even on sensitive Hybrids (CVJ CSK)
Efficient battery drain

💔CONS

Being this cheap, there’s potential QC issue and consistencies. As with many cheap Chifi items
No mechanical volume adjuster
No Balanced Output
Construction and build appearance seems less durable
Needed 90/100 volume for normal loudness on T40RP MK3
Driving power not as great as others, need higher volume on demanding pairing

VERDICT

JCally JA3. It’s very simple, this is a JCally JM6 without a cable attached to it. Otherwise it is identical internally to JM6 and CX-Pro 31993. And of course despite being direct mount, it sounded exactly like JCally JM6. A great option for those preferring super compact Dongle (which are quite limited even now).
