As in the header, I remember very little about this book or series
Some guy who is a key leader, either Earth Government or a corporation or a power bloc. There was a space trading element but I really can't remember anything about that. I don't think this person was the main character.
The key point I remember is, from the moment he wakes up, there's a little device or implant at one of his ears. All day long he gets updated on stock market and political info and military dispersals. A continuous low murmur.
