Hands free kit microphone problem

I am having a problem with my LG TU 550 Hands-free car kit, People on the other end of the connection cannot hear me properly, insted of sounding loud and clear, it is like background noise, I almost have to shout for them to hear me properly. Is there any solution to this problem?

    Bought the Plantronics hands-free wired headset (MX-256-X1) and had the exact same problem. People on the other end couldn't hear me unless I held the mic right by my mouth and shouted, and then just barely. Returned it thinking it was defective, but the replacement has the same problem. Then I noticed that when I plug it into the phone, the TTY device symbol pops up on screen instead of the headset symbol. If I switch the mic to mute, plug it in, then turn mute off again, it works okay (though people on the other end still report a slightly muted sound. This headset got great reviews - but so far, only barely acceptable for me, and only after flipping the mute switch.

Why can't people hear me talking when I try to use my TX 550 hands free device. Microphone is not muted.

Hands free needs to be checked especially the microphone.

Sounds like there is a noise cancellation issue. Can you check to see if there is food or other debris in the microphone hole?

I would delete all paired devices from the Parrot kit and delete the Parrot kit from your phone, then remove your battery from your phone for 5 mins, then repair as a new phone. If this does not work you have a microphone issue, check the wire is not trapped behind one of the trims.

LG neon i can hear people talking to me but they can't hear me

If your phone isn't muted, you have a bad microphone at your phone, you'll need to replace it or you'll have to use always a wired or a bluetooth hands-free device.

Bluetooth issues

The solution was quite simple. Always give your new hands free kits the full charge before trying to use it. I never thought it would make that much of a difference but it obviously does. I feel terrible about all the hands free kits i have taken back as faulty.

Hands free car kit

  1. The microphone socket is very tight. Ensure the microphone plug is pushed in completely on the handsfree Control Unit.
  2. There is a small cable and plug inserted into the top of the handset carrier. This is only a plug holder. The speaker will only work when this plug is plugged into the earphone socket on the side of the handset.
