It’s the Quattro version of the Enzo 3D.
So it will have the same kind improvements we saw between the Linx 3D and Quattro. The most substantial of which (that you’d never be aware of) is a BLE Aerial that offers 4-6dB extra gain - this virtually guarantees the signal between the device and the paired accessory/phone/programmer, which means that fewer errors are thrown, there are less dropouts and less crashing of the comms on either end.
Additionally, there’s more processors in there, the feedback manager is better and the speech processing offers more enhancement as does the refinement in directionality.
So: will it sound any different ? Possibly. Does it contain a significant upgrade? Yes.
