Hi, Please guide me to links/scripts if these questions have been addressed before. I want participants to use headphone and keep the volume settings as same for all.
Is there a way to know that respondents are using headphones indeed and not speakers? Or, abort the script unless headphone is jacked in? Also, is there a way to know the volume settings of respondents in the recorded data? (so that we can filter results later on)
Thanks
