LG Headset can pair with PC and I can hear but the mic is not working

Since it is Bluetooth, you have to pair the Bluetooth to your host computer or device. Find the correct window or screen and put it into discover mode, do the same with the headset. RTFM

Microphone might be bad. Try deleting pairing and try again. If still doesn't work then might be bad mic.

1. CompatibilityThe PS3 supports only one headset at a time. Multiple players on the same console will have to share.
Bluetooth:

• The PS3 uses Bluetooth version 2.0, and is compatible with all earlier versions (1.0, 1.1, 1.2). 2009 may see version 2.1 Bluetooth headsets hit the market, so you will have to try it for yourself on PS3.
• All brands of Bluetooth headset should work with the PS3.

USB:
USB (wired) Headsets can also be used with the PS3.

• Any of the PS2 compatible USB headsets should work with PS3 games.
• USB headsets are required for PS2 software used on the PS3.

Not Compatible with Bluetooth Stereo Headphones:

• The Bluetooth audio signal for PS3 only carries voice chat. The game sounds and music are played through your TV or stereo receiver only.
• If you want to listen to the gameplay with headphones then they will have to be compatible with your TV or stereo receiver.

2. Setup
A Bluetooth headset has to be registered, or "paired", with your PS3 before it can be used.

• Make sure your Bluetooth headset is fully charged before you begin.
• Check your headset instructions for entering "pairing mode". Activate your headsets' "pairing mode" so it can be recognized by the PS3.
• On the Cross Media Bar (or XMB) of the PS3 go to the "Settings" tab, then down into "Accessory Settings", then down into "Manage Bluetooth Devices".
• With your headset in pairing mode, follow the onscreen instructions and let the PS3 scan for your headset. When your headset is found, follow the prompts and enter a pass key (if necessary- the default is usually 0000 for all brands). The pairing should now be complete.

If you're using a USB (wired) headset, just plug it into one of the ports on the front of the PS3 (the system should auto-detect the USB headset).

Mic Test and Volume Setting
After pairing a Bluetooth headset, or after plugging in a USB (wired) headset, return to the XMB. Go to "Accessory Settings" and choose "Audio Device Settings". You can test your headset here.

• Your headset should appear as the audio input/output device. If not, just use the D-pad to highlight the Input line, then scroll until you see yours. Any microphone you have used with your PS3 will be listed, but only the current one will be available to select.
• Set the "Microphone Level" to 3. You can change the level any time if needed.
• Speak into the headset, and the level bar at the top of the screen should move at the sound of your voice.

You can also view a list of Bluetooth accessories you have registered in the "Manage Bluetooth Devices" tab under "Settings".
If your mic doesn't appear there then try pairing it again.

There are more ways to configure the audio input and output that can be useful:

• Set the input to (your mic) and leave the output on (default)- one person can chat with the other players, and the replys will play over your TV speakers rather than into your mic. Great when sharing one console because everyone can hear the team talk.
• Set the input and output to (default)- you will hear the game sound and voice chat through your TV speakers but won't be able to talk back. Great if you don't have a headset, or if you want the room to hear the team chat.
• Set the output to (default) to use stereo headphones with your TV or receiver. Then set the input to (your mic) and you can chat while wearing stereo headphones. Keeping the mic close to your face could be a problem since both ears are already taken! You could try a USB desktop mic and see if that works.

3. Troubleshooting

General:
If you are having trouble with a headset after it is paired with the PS3, there are a few things to check first:

• Make sure your headset battery is charged and working. Be aware that some brands/models will need to be paired again after each recharge. It's not a problem, it's just the way those models work.
• Make sure your controller is charged. Lots of strange things happen when the controllers don't have enough power, like dropouts and headset interference.
• The headset should be set as the input/output device from the XMB.
• For Bluetooth users, make sure there are no other Bluetooth devices in use near your PS3. Also try to eliminate any other radio frequency interference if possible.
• For USB users, make sure the connection is secure and there are no wire breaks.
• Update your console to the current available firmware.

Pairing Problems:

• If the PS3 cannot locate your headset, make sure that your headset is in pairing mode before you start scanning. The headset instructions will tell you how to set yours to pairing mode.
• If your headset is missing from the device menu after you re-start your PS3, you will have to pair again. Many headsets will only "remember" one device at a time, so you may have to register again after using your headset with a phone.
• If your headset appears on the Audio Device menu but is "grayed out" or not selectable, it is not connected. Make sure the headset is charged, and that it is on in standby. I should connect automatically when the Audio Device menu is selected. Tap the call button on the headset if it does not connect, or click on the Connect Bluetooth tab on screen.
• Make sure no other Bluetooth devices are in use nearby.

Voice Chat Drops:

• Most in-game voice chat drops are simply network lag. Usually they go away after a short time, so be patient. In extreme cases you may have to leave a game and return to reset the chat function.
• If you use wireless internet, a low signal strength to your modem/router can make voice chat malfunction. Make sure your wireless signal is as strong as possible to your access point.
• Sometimes a headset will quit after changing discs to another game. Go to accessories and select your headset again.
• Make sure no other Bluetooth devices are in use nearby.

Try charging it for 24 hours, this should reset the headset. then completely delete the pairing and repair the device. If this doesn't work, there could be a problem with the mic portion of the headset.

same here..

Yes you can. Just go to accessories or audio device settings. Have your headset on and hit connect bluetooth device. The key it asks for should be 0000. If that doesn't work do a quick search online and you should be able to find one that works.
