Can you compare them to any other IEMs that I might have? KZ-ATE, KZ-ZS1, W1 pro. How is the soundstage? Mids?
I can give some impressions against the
KZ-ATE....
KZ-ATE (with default sponge tips) VS
KINERA BD05 (default silicone tips):
BASS:
With the ATE, the bass is balanced and quick with no bloat what-so-ever. And, even though the sub-bass is not as deep as I prefer, the details and transparency is really satisfying with many selected genres. The BD05 has more of a solid bass signature with a strong presence in the mid-bass that contibutes very well with the lower mid-range.
MIDRANGE:
The ATE has great midrange presence and transparency (remind you with the sponge tips) and provides good coherency because of it. The BD05 plays very well with its BA armature partner where the dynamic takes care of most of the MID and all lower ranges, while the BA armature takes care of the MID and all higher ranges to the "T".
TREBLE:
The treble on the ATE is nicely detailed to the point where I can hear some micro-details coming from a dynamic driver, but can be somewhat picky on bad recordings. The BA on the BD05, does a very good job playing well at higher ranges and peaks nicely on top without sounding strident or harsh.
SOUNDSTAGE:
Soundstage on both the ATE and BD05 are very good, but play differently because of their different signatures. The ATE sounds transparent and imaging is great all around, while with the BD05, the soundstage can be just as wide, but not as deep (or lacks a little depth, per say). Headstage sounds a little more present and realistic with the ATE, while the BD05 sounds a little dryer, but precise.
CONCLUSION:
They're both great IEM's for their price range and many here can benefit from their different signatures.
