Worth it.

1. It can identify small signals. The value of the differential signal of the Music Ribbon Frey 2 signal line is largely independent of the precise value of "ground". It can resist the interference of the power supply very well and is worth buying.

2. Equal length. The length of the two lines of this line should be as long as possible to ensure that the two differential signals maintain opposite polarity at all times. It is worth buying.
