Retail Audio


Feonic’s invisible speaker technology, turns your window into a speakers that delivers sound onto the pavement all along the length of the window. The sound helps turn glancers into lookers and lookers into engagers.

    Independent Research carried out by Retail Marketing Services Ltd compared two windows, one with sound one without:
  • When weighted against the passers by, those who interacted – either glanced or stopped & looked - with the window display increased by 56%
  • Those who glanced at the window whilst passing increased by 58% weighted
  • Those who stopped & looked at the window whilst passing increased by 49% weighted

"Over the period that the Whispering Window was installed, we noticed a 40% uplift in sales across the whole of the audio and TV department"
