Question about GN Netcom GN 9120 Professional Headset

High pitched squeel

When someone calls in and I answer the call using the headset I get a high pitched squeel in my ear and the other person's ear as well. If I make a call out it works just fine no squeeling sound. I have tried moving the headset base further from the phone but I can only move it so far. I don't know what else to do.

Turtle beach x32 high pitch noise

I had the same problem. I was using Energizer Rechargeable batteries that were fully charged and the same thing was happening to me. I took out the batteries and switched them for the ones that originally came with the headphones and they were working perfectly fine. For some reason they don't like Energizer Rechargeable batteries. I haven't found another brand that works yet, but I hope this helps.

High pitched sound when attempting to use the headseat rather than the handset. I have tried all of the settings on the side of the desk moduel.

It sounds like it may be plugged into the wrong jack on the phone base. The cord from the S10 HAS TO BE plugged into the jack where the curly cord from your phone was plugged in. You can't use the headset jack, this will cause the high pitch sound you are hearing.

Good luck from Headsets Direct!

Bose Aviation headset Series 2 has high-pitched squeal.

Try wearing the headset the "wrong way". The left side of the headset on your right ear & the right side of the headset on your left ear. I have the QC15 with the same problem and it worked for me. Good luck!

Charging plantronics 520/521

The red light will stay ON while charging and will go OFF when charged. Charging does not take long. Since you have no manual, you turn the headset on by pressing down or toward your head and holding the button down. If it's in your ear already, you'll hear a four-note upward pitch sequence to indicate it's powered on. If it's out of your ear, you'll see a red light, followed by a blue flashing light.

Set your phone into Bluetooth mode and make sure in the menus that Bluetooth is "discoverable" or some such lingo to search for the headset. The pairing code for this headset is 0000 (zeros not O's), so when you set your phone up to pair with the headset and the phone wants a pairing code, enter 0000. After the pairing is completed and Bluetooth is activated on your phone, you should hear a high pitched single tone to indicate the headset is in range and communicating with your phone. If you separate from your phone over about 30 feet or if communication is interrupted with your phone for some reason, there will be a lower pitch single tone, indicating loss of communication. After pairing, you should not have to go through the code sequences or setup again unless your phone is completely reset. You should be able to set your phone to Bluetooth, turn your headset on and hear the four-note sequence, followed by a single high note.

Push the switch up or away from your mouth to step the volume up. Likewise, push the switch down or toward your mouth to lower the volume. I've never turned it down, it's always a little low in volume to me even at max.

Push down or toward your head BRIEFLY to answer or hang up the call. Depending on your phone, you can also activate dialing or voice command by using this same brief push. There is a brief delay between pushing the button and being able to talk on most phones, so you might listen for a volume or noise change before talking.

To turn the headset off, push down or toward your head and hold the button down. You will hear a four-note downward pitch sequence to indicate power-down. If you're looking at the headset, you will see a steady red LED, then it will go off. By the way, a flashing red LED indicates need to recharge. A flashing blue LED indicates the unit is operating correctly.

Remember, battery consumption on your phone is greater with Bluetooth turned on, whether you use the headset or not. Bluetooth units constantly stay in touch with their partners, much like your phone stays in touch with the cell towers. So watch your phone's battery indicator a little more closely until you get used to your talk patterns and general use. Depending on your situation, your phone may not use much more battery than before.

Standby (inactive but ON) time on the headset is very good, and battery shelf life (power OFF) has been good also. These headsets are extremely useful in a car or if you are busy with your hands during calls. Just remember to use your head (pardon the pun) and not take or make calls while doing something dangerous. You wouldn't do that with your corded home phone, would you? The vote is still out, but they do tend to look a little nerdy when worn constantly in public. I hope you get as much benefit from your Bluetooth headset as I have from mine. I thought they were completely Nerdsville before, but I'm a convert now. Good luck.

Broke the ear hook for the Motorola h500 bluetooth headset

The ear hook on my H500 broke as well.  I called Motorola (866-289-6686) and they are mailing me a replacement.  Even though This bluetooth has a 1-year warranty.  I purchased mine in Jan. 2007 and was covered but the rep didn't verify anything regarding the purchase date so even if you're outside of your warranty, you might still give it a shot.
