I have a Dell n5010 (15R) laptop, and I also have a bluetooth headset which I use all the time while using the laptop.
Well, The headset works perfect all the time, I can listen to music for hours without a single problem.
But when I play games, there are problem. The sound periodically disappears and appears again, it sound like the reception is low, but the headset is like 50 cm away from the laptop. The problem happens only when playing games so I guess it's something related to the fact the computer is heavily loaded.
