Customer Reviews

Based on 1 review
Smooth, detailed, pleasant, and a little pricey.

This is my second pair of all-BA iems, the first being the TRN BA5. I'd like to preface my impressions with saying I am no audiophile, just a hobbyist. My eartips: final audio e-type, since sound can be tip dependant. This is all my opinion, so YMMV.

This iem considerably smooth to me, with good texture all around. The bass is powerful enough, and it sounds better than the BA5's. The vocals seem clearer, too, and the the treble is smooth and detailed. but I do imagine it'd be harder on some people's ears.

Fit is good. Comfortable, decent heft (feels premium but not too heavy.) The typical metal build is solid, and the powder coating they use looks and feels premium. The shell is actually similar to the shape to the moondrop starfield if that's any indication of comfort, but the BA8 has better isolation.

Accessories are pretty lame for the price point. Standard TRN eartips, and the wire it came with is doodoo. It's like the stock copper KZ cables. (I was gifted an 8-core cable, but I wouldn't count it since it is not standard) but the aluminum carrying case feels nice.

I can't say the BA8 is 2x better than the BA5 considering the price, but it is a big improvement. I really enjoyed it.

I don't know how it compares to it's contemporaries like the KZ AS16 or the CCA C16, so I'd like to see them compared.
