A:Answer Hello Blazingskywoman! The H390 Wired USB Noise-Cancelling Over-the-Ear Headset uses a USB connection, so it needs to be connected to a PC, Mac or Chromebook computer in order to operate. It will work with a lot of business apps on the above platforms, but if you need to connect the headset directly to a phone, you'd probably require something with a RJ9 jack, and this would not work unfortunately.
