Bluetooth loud mechanical noise

[Nish]

I am having a problem with my ps3 picking up bluetooth headsets, they are all usually perfectly fine. I myself use 2 different model sets and randomly and more often the last 2 nights I've gotten a very loud sound that is received by my ps3. The sound is continuous and gets louder if I speak, I cannot hear the sound myself unless I go to audio devices on the xmb. Both headsets do it at the same time and while using my uncles official ps3 headset I got the same result.

Any tips would be happily received.
