This is an amazing work headset for the price. They are a little tight around a big head like mine, and it won't win any awards for how music sounds so I took away 1 start for that, but for phone work it is excellent, voices are heard clearly and the microphone picks up my voice clearly as well. I even used it for some voice over video work and my voice sounded like it came from a much more expensive microphone. These are overall better than the headsets my job provided and they cost 3 to 4 times as much as these. For call center and phone work, these are the best overall for the price.
