Verdict

The call

The clearest difference is update cadence: K at every 2 months against JBL Performance's every 5 months. K also leads on device support (3 vs 1) and iOS requirement (13.4 vs 16.4). JBL Performance's advantage is ratings volume (6 vs 1). On price, rating, review sentiment and ads there is nothing between them.
