Sudden loud static noise on bluetooth hea…

I'm using LG Tone+ (HBS-730) bluetooth headset on my MacBook Air mid13 on OS X 10.10.2 Yosemite.

Since a few days ago, while I was listening to music and such on my headset, sometimes, a loud static noise (max volume I think) started suddenly, which shocked me and led me to quickly pull the earpieces out. No other sound is recognizable since this static noise is so loud. The noise does not stop until the bluetooth is disconnected by either turning off the headset or the bluetooth module from mac. Turning the headset on again, it works again normal.

While the noise exists, if I mute the volume on mac, the static noise stops, but comes back when I increase the volume again. Volume control on the headset did not do anything.

I'm suspecting either the bluetooth module on the laptop or the bluetooth module in the headset is bad, but couldn't test with another headset as I don't have anything else. It happened 3 times for the past 3 days I have been using it.

MBA is a little bit over 1 year old and the headset is about 1.5 years old, no related problems were experienced in the past.

Does anyone have any clue or similar experience?

Hi friends of the good sound. I researched a little bit about the issue that i found out with regards to the Notification Center (NC) and Bluetooth headphones.

Following thing I experienced:

If I use my Bluetooth headset (Jabra Revo Wireless a4.0.0) and immediately open the Notification Center (NC) the sudden static noise appears regularly.

Now I deactivated the NC. The sudden static noise didn't appear since last hours. My question to you is, if you can test following instructions at your Mac?:

1. Open Terminal.app at your frequently used account
2. You will see following command in Terminal: MacBook-Air:~ [your username]$

   or MacBook-Pro:~ [your username]$ --> depends on your Mac

3. Type after "$": launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist

   --> This will deactivate your NC after you log out and login to you account again

4. now log out
5. log in
6. You will see the Icon of NC on the right side, but if you click on it it will not start (because deactivated)
7. Done!

So my question to you is: Are you experiencing further sudden static noises in daily use with the Mac? Let me know.

I think the NC is buggy and is interfering the Bluetooth signal. So I don't need the NC, it is only an additional app.

IMPORTANT:

For people who want to get their Notification Center back please follow these instructions:

1. Open Terminal.app at your frequently used account
2. You will see following command in Terminal: MacBook-Air:~ [your username]$
3. Type after "$": launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist

   -> This will activate your NC after you log out and login to you account again

4. now log out
5. log in
6. You will see the Icon of NC on the right side, if you click on it it will start like normally used
7. Done!
