Frequently Asked Questions

  • Is the NC-181 compatible with Windows 10?

    Yes. The NC-181 is compatible. Just plug it into your sound card.

  • Can I use my new NC-181/NC-181VM with my old USB-SA adapter?


  • Will my headset work with Skype or Zoom?

    All Andrea headsets are compatible with all major communication platforms such as Skype, Zoom, Hangouts, Meet, Google, WebEx, Microsoft Teams and WhatsApp.

  • What is the difference between the NC-181, NC-181M, NC-181VM, NC-181VM USB and the NC-181VM USB-C?

    NC-181 has 2 separate 3.5mm plugs, one for input and one for output. The NC-181M indicates the unit has a single shared audio 3.5mm plug for input and output, it also has an in-line Volume/Mute control. The NC-181VM has 2 separate 3.5mm plugs as well as an in-line Volume/Mute control. The NC-181VM USB indicates that the Andrea USB-SA External Digital Sound Card is in-line, or built into the cable, as well as a digital in-line Volume/Mute control and plugs into a standard USB port. The NC-181VM USB-C is the same as the previous but plugs into the newer USB C ports. 

  • I only get static or what you might call loud distortion noises through my headset.

    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.

  • Is there a replacement foam kit for the NC-181?

    Yes. The part number is C1-1007200-4 and can be found in our accessories link.

  • Will my music files play in mono through the NC-181?

    The NC-181 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 and routed through a single audio channel. In the case of the NC-181, 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.

  • What is the white dot located on my microphone?

    The white dot located at the end of the mic boom (just before the foam windsock) indicates which way the mic should face. The white dot should be facing your mouth.

  • How do I request warranty service?

    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.
