I have The Three and there is a knob on the top that you can switch between input sources, with an indicator light that shows which source is being used. There is a wi-fi symbol that indicated when the Play-fi feature is being used. On the front of The Sixes right speaker there is a similar configuration - there is an indicator light for each input; however there is no wi-fi symbol like there is on the The Three.
So - do The Sixes have Play-fi or not? It seems weird that they wouldn't. I can't find any description that talks about Play-fi for The Sixes - although on the London Drugs website it says Play-fi in the product title: https://www.londondrugs.com/klipsch-the-sixes-self-powered-speakers-with-play-fi---pair---thesixesw/L9321969.html
Perhaps they did not have play-fi at first, but then it was added?
Can someone please clarify this for me?
