First of all, I commend Logitech for its clear and crisp sound. However, my headset's mic does not work on my Dell laptop. It works perfectly on my smartphone and ipad but not on the laptop. I tried calling Dell Support if they could provide any solutions, instead, they gave me a generic answer from google saying that the headset has the problem. I strongly disagree though because it works on other devices. I hope someone has the it intelligence greater than Dell Customer Support agents to help me with this problem. I have struggled with this dilemma for almost a year now.
