I've been reflecting lately on the curious case of the BA10. Upon first hearing it (and reviewing it) I was somewhat undecided about whether or not lightning had actually struck twice for KZ (the ZS6 being the first lightning strike). After evaluating the BA10 for several months I can confidently say that the BA10 holds up incredibly well. Yep, I can wholeheartedly say that "yes", indeed lightning has effectively struck twice for KZ Acoustics with the BA10, albeit the second time around it was more of what I'll refer to as a quiet storm. I'd like to see KZ revisit the BA10 tuning but this time in a more ergonomic housing since the BA10's unorthodox approach to housing was so polarizing.
That said, I have no complaints or concerns regarding fit or comfort with my BA10.
Looking at how the 10Pro and C16 have been so well-received, and rightfully so, I'd like to see KZ simply double the driver count on a BA10 replacement to further increase definition, separation and perhaps layering. Truthfully, I don't know if they can pull it off; I'm almost certain that the aluminum housing, lack of tuning tubes and unused space (40%+/-) inside said housing contribute to the homogenous and cohesive sound that pours through the nozzles. The BA10 is a very good IEM but in all candor, I doubt KZ can pull off duplicating the sound.......but I can hope.
Bottom line:
If KZ can duplicate the BA10's sound signature with the minor improvements mentioned above AND keep their legendary price to performance ratio (perhaps $90+/-) then it'll be a landmark IEM.
.......but it MUST BE ALUMINUM (and SHOULD have the vented faceplates) and it MUST BE ERGONOMIC or it simply won't work for interested parties.
The BA10 sound signature....
It's lover'ly
