One of the cables wasn't locking as tightly on the MMCX connector. It was still electrically connected, but it was much easier to pop out than the other side. Looking closely at it, it was excess rubber that was preventing it from solidly locking. I did trim it and locks much more similarly to the other side now, but SQ wise, the A3 isn't impressing me as strongly as the A2 did and the trimming had no effect on the SQ.
