Is It Safe To Use Headphones 1 Week After Canalplasty Surgery, Or Should I Avoid Them For A Longer Period?

Hi. I have just had canalplasty surgery and have been signed off work for 7 days I often have to use headphones (not earphones) for meetings at work .... sometimes for 5 or 6 hours per day. Will this be OK to use them just 1 week after surgery or should I try to avoid this for longer? If so how long do you recommend?
