    You do not ned to open it up.... the best fix (but still might not work) is to fill a small container half-way with p[lain white uncooked rice (sounds silly, but trust me), put the 975 on top of the rice, and fill the rest of the way with rice. Put it someplace worm for a couple of days, and then try it. Unless the HS is already ruined, this will work. I did it with a Blue Ant and with a 975. (Twice for the 975... the first HS I did this with works. The second was too far gone.)

Rinse it with distilled water after you open it up and then let it dry for a couple of days. Also it`s important that you do not turn it on until it has dried out completely.

    No screws hold it together, just adhesive. Check out these pictures of a similar disassembled Plantronics.

SOURCE: PL-CS55 headset lifts receiver but only get buzzing sound in

Try a system reset:
1. Lift the headset off of the charging cradle (the base).  Make sure the headset is turned off.  The green light on the base won't be on if the headset is turned off. 2. Hold down the call answer button on the headset at the same time as mute button.  The mute button is found on the little black wheel on the top of the headset.  Use the tip of your finger to push it straight in. 3. Hold both buttons until you see a green light on the headset flash.  It will be right below your thumb.  Hold both buttons until the green light flashes for a series of 2 flashes.  Then let go of both buttons. 4. Put the headset back on the charging cradle and wait 30 seconds.  Lift it back off and try again. 5. If this doesn't work repeat the process once more or try a resubscription.
Resubscription procedure:
1. Put the headset back onto the charging cradle.  Make sure the red light on the base is on and the yellow light is flashing. 2. On the back of the base there are two buttons for the microphone adjustment that can be pressed down.  Press both of those down until the red light and yellow light on the front of the base start flashing. 3. While the headset is still on the charging cradle press and hold the mute button until the red light on the base goes solid, and the yellow light stays flashing. 4. Unplug the power to the base and then plug it back in. 5. Wait 20 seconds and try.

SOURCE: I have a CS60 Handset doesnt work when the headset is connected

First setup the headset as follows:

  • Locate the 2 ports on the bottom of the CS60 charging base. One has an icon of a "full telephone" and the other has an icon of a "hand receiver."
  • Unplug the hand receiver from the base of your existing telephone and plug it into the "hand receiver" port on the CS60 base unit.
  • Then take the short cable that came with the CS60 and plug it into the "full telephone" port on the base of the CS60.
  • Plug the other end of the short cord into the hand receiver port of your telephone (where the hand receiver just was).
  • Make sure the AC Power is plugged into the wall, and then you can adjust the configuration settings.
To be able to hear or speak through the handset, either place the headset back into its charging cradle or press the call control button on the side of the headset. The talk indicator light on the base should go off and no sound will come through the headset.

Note: Make sure that the cables are connected correctly and the handset cable is connected to the base of the CS60 base.

    Headset cutting out

    I was having this issue while using this headset on my PS4. I bought a small,2ft USB extension, to move it away from the PS4 console by about 2 feet and now it works perfect. It was something about the interference from the remote controls. Hope this helps.

    My mic on my headset stop working

    If your mic has stopped working this may be due to the fact that the hardware has finally worn out and may not work anymore. If the product is less than a year old try contacting the manufacture to claim your warranty.

    I need to repair my headset Genius HS-04SU. The volume control is not working

    You can disassemble the volume control and clean it. The potentiometer is probably not making contact or is dirty - it is just a variable resistor.

    Pantech c150 stuck in headset mode - no headset plugged in

    open the headset port on top of phone and push the little square adapter connector part down with your nail, and that will take it out of headset mode..

    If you have a Headset symbol stuck on your screen but have no headset plugged in, its probably down due to the pop port at the bottom of the handset.
    This normally shorts or fuses together inside the phone when exposed to some type of liquid.
    You will need to take this to a Nokia Care Point and they will need to check inside the handset for you.

    If it has got wet, then it is not covered under the manufacturers warranty.

    Try drying the pop port with a hairdryer.
