Great price on these headphones. I use them to garden/work in the yard so I can wear a hat and still have good ear protection from the noise of my small engines. I can answer calls, play/pause music, control volume etc... It's best feature as advertised is the RANGE. I get really good range for this device. I'm not realizing the 150 ft advertised distance but I am getting way further than I ever have with other bluetooth devices. Keep in mind that getting the maximum range is line of sight but I have kept my connected phone in the house and the headphones on outside without a problem.
