I got these just to listen to movies and so forth after the kids and wife went to bed, but I found they were much better quality than I first suspected due to the low price. I had no connectivity problems at all. The range easily covers my entire house, but would proably only be the advertised 150 ft without any walls in the way. My house is only 75 ft long with the transmitter on one end there is only one spot where I get even a glitch in receptoin all the way at the other end of the house. Yes, I looked like a dork walking around my house trying to find the range. :)
