Verdict
The clearest difference is update cadence: Marshall Voice at every 3 weeks against Harman Kardon Controller's every 2 months. Marshall Voice also leads on iOS requirement (10.0 vs 14.0). Harman Kardon Controller's advantage is device support (4 vs 2). On price, rating, review sentiment and ratings volume there is nothing between them.
