I can not hear anything and the phone has the headset icon on, how do i get it off

There may be linking issues between the headset and the phone. Page 11 of the user guide offers these suggestions. Also, here is a link for re-pairing your headset to the phone:

Plantronics Explorer 230 Pairing Instructions

Remember that you want to purge any possible bluetooth interference from your phone.

"Callers cannot hear me or I cannot hear caller/dialing tone:
The headset is not turned on or the headset is not connected to mobile phone. Press the call control button for 2 seconds until you hear a beep or see the indicator light glow blue to turn headset on.
Your headset is out of range. Move the headset closer to the phone or Bluetooth device.
Your headset battery is drained. Charge your battery using the AC power adapter supplied.
The listening volume is too low. Press the volume key up (toward the earloop) to increase the sound heard in the headset."

Good luck from Headsets Direct!

you have headset problem you should contact with mobile enger. and 2nd thing check your profile on the mobile

it means you have the phone in headset mode so it is sending audio to headset not speaker ...should be able to turn it off in the phone settings

Problem is on your Headphone Interface, go to nearest service centre and change that part. or clean that part

open headset port, push down on square connector, cover port and it will be gone

The headset icon always appear in my nokia n70 and cannot remove and when i connect my headset ... it doesn't work . with or without headset the headset icon always appear in my screen .

maybe you had your phone wet on the bottom part where the headset is to be plugged in. bring it to the nearest repair shop for the just to clean the metal contacts then, your icon will be gone

i fixed this problem

The phone came with a headset. Plug the headset in and out a few times; it should reset the headset icon and phone can be used regularly again

Is the headset paired and connected to your phone? Is bluetooth turned on in your phone? Look for the bluetooth icon on top of your phone's screen. Let me know what model phone you have and I can help you troubleshoot.
