Razer Leviathan Sound is much louder from bluetooth than it is from wired connection.

I am running a Razer Leviathan RC30 from a macbook pro. I am able to get much better sound through the bluetooth connection rather than the wired connection. I upgraded the cable for the wired connection but still no luck. The reason why I would like the wired connection is there is an ever so slight lag on the bluetooth sound when I am watching video so the lips of the person speaking are always a little bit in front of the sound coming out of the speaker. I have tried all the Apple sound adjustments but to no avail. Is this a known issue with the older Leviathans?
