Key words: ANC, ANC function, ANC performance
1， ANC function can ONLY reduce the noise of low frequency noises in the range of 20HZ-800HZ. Also, although the consistent Low Frequency ambient noise can be reduced effectively, the noises can NOT be canceled completely.
2， The noise canceling effect may not be pronounced in a very quiet environment, or some noise may be heard.
3， Due to this unique feature some frequency bands sound quality may be affected relatively.
4， ANC031 is a cost-effective entry level ANC headphone with up to 22dB noise cancellation performance. We also have other models of ANC headphones with better ANC performance - ANC041 (up to 37dB ANC performance - $99.99).
Here are two options –
Option1 - Please let us know (contact support@avantree.com) if you’d like to pay the difference and change other ANC headphones.
