I did have my mobile phone very nearby also connected to the bluetooth headphones while my laptop was still using 11n wifi. I didn't have any noticeable issues with bluetooth there. But I got the feeling that my phone's android drivers + hardware for bluetooth are tuned better than the laptop ones, so maybe that just means the phone is just better at jumping frequencies to avoid. I guess the best test would be the same laptop model in direct proximity, but sadly I only own that laptop once. ;) I hope wireless interference wouldn't rule out that some driver work would be considered to make it work better - after all, both chips are in the same laptop and as per the intel comment, bluetooth is supposed to work despite of wifi activity.
