The red and green lights do not turn on. Only the blue series has illumination if the cable is in specific positions.

Well, it's not worth it because:
1. Within 2 days, it started to break and I had to use a very strong glue.
2. It has absolutely nothing to do with the box. Neither music nor mobile phone nor anything.
3. I don't know if it's just mine, but in the blue color, half of it doesn't work, meaning it's like that. Or maybe it's the same with other colors like yellow and white.
I won't buy it again, but it's not that bad. I've had it for two weeks now
