try removing the pairing to your phone and pair again. If this does not work try pairing your headset to another phone and if it does it on that phone then something is wrong with the earpiece return for repairs if under warranty or if you are willing to pay for the repairs if out of warranty or replace ear piece all together as they are reasonably priced these days. If the ear piece works fine the other phone something has gone wrong with the bluetooth side of your phone return for repairs or replace depending on what you can afford to do. I hope this helps.

When joining (or pairing) a Plantronics bluetooth headset to another device a lot depends on the other device. Assuming that you know the necessary steps of your phone, PC or other device for connecting a bluetooth device, all Plantronics headsets pretty much follow a set pairing procedure for connectivity. This one is for the Discovery 975:

1 Turn on the Bluetooth feature on your phone.
2 Turn the earpiece on. Press and hold the call control button until the indicator flashes red/white.
3 Use the commands on your other device to locate and select your earpiece. 9xx Plantronics.
4 If prompted for the PIN code or Passkey, enter 0000.

Pairing is successful when the indicator on your earpiece flashes white.

Note If your phone supports Secure Simple Pairing (SSP), you will not need to enter a PIN code or Passkey.

Good luck from Headsets Direct!

its a hardware problem. try another ear piece if it still don't works go to your vendor and replace the phone

The 500A base station is definitely compatible with the 510 earpiece. If the earpiece is turned off or unpaired the base station's red power light will be flashing. If the earpiece is already off, try turning it on by holding down the little black button on top. The base station will automatically try to find the earpiece and the blue light on top of the base will come on. If the earpiece is already on (slow flashing blue light on the mic boom) turn it off and back on again and wait for the base to find it.

My HTC Touch Diamond paired with BTB-200 after I installed the JETware software. When pairing make sure that your bluetooth is on and visible, and that under services only the box for "hands-free" is checked.

Press and hold the call button while the boom is in the off position for 4 to 5 seconds. The blue indicator light should come on and stay on. The unit is now in pairing mode. Initiate you phones feature of searching for bluetooth devices and pair the two together. The default passcode for the H700 is "0000" four zeros.
Good Luck

I bought a new HS850 and guess what, I got this hearing problem on the very first day ...phew ! I did the pairing with my Motorola A1200 phone and it worked for once, even the sound was coming in the earpiece and then I put it to charge for the first time and once done, I again started it up and it got connected with the phone and after that there was no sound in the ear piece. I was going nuts....about what could be the problem.

So i decided to delete the earlier paired profile from my phone and do the pairing again and guess what...It Worked....:) So you can try that out too....
