The sound that a headphone, connected with the code100, produces does not include the effects that are placed in sent and return. That is really strange. 

Music played with a phone or tablet that is connected with Bluetooth does go through the effects in the sent and return loop. Really strange again in my opinion.

I would like to know  why it is wired this way and I would be really happy with a solution for at least the headphones!

Kind regards!
