DDJ Ergo Headphone\monitor latency + Traktor 2

Hi, 

I recently bought a DDJ Ergo, and having issues with Latency via the headphones. It seems the headphones are playing the cue slightly behind\forward of the monitors, making mixing almost impossible. 

Has anyone else had this issue before... 

I was using the Wego just before this, same laptop\setup with no problems. 

Thanks,

BD
