So, I got mine and no, it's not the BA version. Driver flex alone in the right earpiece confirms that. Also, the call quality was described to me as "atrocious", so aside from the false advertisement, they are useless for business. The case is great and they actually sound pretty good when I EQ out some of the 400Hz flab and push the low-treble region (2kHz-4kHz) a bit. Even with the false advertisement, if the call quality was good and there wasn't any annoying driver flex (or it was at least consistent on both sides or none at all), then I'd probably keep them for the $51 I got them for.
