other people hear whistling

Bose product name qc 20

 

Hi, i have been using my QC20 with my laptop for zoom calls etc and other people on the call say they can hear a high pitched whistling sound like a kettle boiling - i can hear it myself, but when i recorded a powerpoint presentation, it recorded the whistling noise, so it is definitely there

 

any advice appreciated as it didn't used to do this.  They are less than a year old.
