Well I sold my old 50s and ordered the new hk 50s. I does sound a little better in music. I found the “voice” eq setting to sound best for music ironically. But my whole reason to upgrade was the microphone. The old one would transmit with wind noise during a group mesh. Well unfortunately the new mic is even worse. It is too sensitive even picked up a motorcycle exhaust for the other side of the road. Worse than before. Sena needs a audio sensitivity control for mesh.
