TRN BA5 Review + Rekomendasi 11.11 | Indonesia
Anyone speaks Indonesian ?
prepare for wall of text,he says as follows (3:30 and ahead)
well balanced earphone, airy, detailed & precise, and has "deep lows" with superb articulation, these iem can keep up with speedy/fast paced songs, these are not for bassheads ( that i can agree).
the sub bass can go really low & have a good texture, mid bass felt less pushed, which is great because they dont bother & fight with the lower-mid details.
meanwhile the mid have a good prescense and clean with a great amount of detail, but unfortunately mid-timbre sounds grainy, its not as clean but its good enough, its like the mids in KZ's BA.
vocals are well positioned, in the middle, doesnt get overshadowed by the lows & highs, but for male vocals it lacks the "body" but still detailed, for female vocals, its lash & vivid with excellent detail.
the BA5 strength lies in the highs, the tunings are extended, crispy & an insane amount of micro details retrieval, cymbals, high hats, snares sounds realistic but for treble sensitive be careful
for the soundstage the BA5 is wide with above average width and a good amount of depth
for instrument placement (imaging) it feels accurate & pinpoint
for separation the BA5 feels special because its clean, precise & every instrument can be heard without it drowning each other out
compared to the V90 the V90 is warmer, V shaped & fun sounding compared to BA5 which sounds analytical & well balanced (i agree with this one, even with the V80)
V90 has more bass than the BA5 because DD vs BA
V90 mids are more laid back & has mid bleed, BA5 is more balanced & centered, its a bit forward but just enough
for the highs, V90 is detailed enough but some pit & piercing, compared to BA5 which sounds more linear & more detailed
staging (soundstage) V90 is bit smaller compared to BA5
separation : BA5>V90
