If your device is still not functioning after contacting the Andrea Support Team, you will be asked to submit your proof of purchase via email or fax, verifying that the product was purchased within 1 year. You will then be issued a return material authorization (RMA) number, with complete shipping instructions to return the device to our facility for evaluation. The customer is responsible for the return shipping. A traceable method such as UPS or Fed-X ground is recommended. If the device is found to be defective after evaluation at our facility, a new device will be shipped to you free of charge.

First, confirm that the microphone is not muted in the “Sound” settings located in your computer’s control panel. If not, reconnect the mic. Your computer should ask if the device you just plugged in is a line level or microphone level device. Choose MICROPHONE level. Next, open Sound Recorder and try to make a test recording: Start button -> All Programs -> Accessories -> Entertainment -> Sound Recorder. Click the red record button, and speak into the mic. The green line should start to move as you speak. If not, connect your mic to a different port on your PC and try to make a recording again. Repeat these steps until the green line moves when you make a recording.
NOTE: If you recently upgraded your operating system, you may need to update your sound card drivers by visiting the manufacturer’s web site.

No software is required. Simply plug in the headset, and set it as the default audio device on your PC.

• Windows Vista, Windows 7, Windows 8 & 8.1, and Windows 10 users:
  In your “Sound” settings in the “Playback” tab, you will see a list of available devices. Right click the speakers you wish to use with Skype, and select “Set as Default Communication Device”. You should now see a green telephone icon next to the chosen device. Next, open Skype > Call > Audio Settings. In the “Speaker” settings select the speakers you wish to use while in Skype. Then “Save” and exit.
• Windows XP users:
  Open “Sounds and Audio Device Properties” located in the control panel. In the “Audio” tab ensure that “Use only default devices” is NOT checked. Next, open Skype > Call > Audio Settings. In the “Speaker” settings, select the speakers you wish to use while in Skype. Then “Save” and exit.

This is usually a soundcard driver issue when upgrading your OS. Try going to the soundcard manufacturer’s website and search for the Windows 10 driver version for your soundcard.

VM stands for Volume/Mute, as the headset has an in-line volume control for the headset speakers, and a mute switch for the mic.

First, eliminate the possibility of a bad audio port by plugging your device into another computer, or by trying another headset on the computer in question. You may also try cleaning the plug with rubbing alcohol and a cotton swab to eliminate any oxidation. If the problem persists and you are within the 1 year warranty period, contact the Andrea support team. Please have your proof of purchase handy.

Yes. The part number is P-C1-1007200-4

The NC-121 is not capable of converting a stereo or multichannel signal into mono. Mono, monophonic, or monaural, describes a recording where all the audio signals (typically a left and right signal) are mixed together and routed through a single audio channel. In the case of the NC-121, this must be done before the signal arrives at the headset’s single earphone, otherwise you will hear only the left channel side of the audio. Windows XP has the ability to convert a stereo playback signal to mono, but this feature was dropped in later versions of Windows.
