Maybe it was because I was born before we had cell phones and computers, but I was led to believe that if you didn't have blue tooth capability on your PC, you could plug this in and then the computer would be blue tooth compatible. My HP desktop didn't come with blue tooth, and runs Windows 7, so I thought this would be an ideal addition. It did nothing when I plugged it in. Three little audio chirps when I plugged it in, but that was it. Thinking maybe I did something wrong, I went to the Insignia website hoping to download the full manual instead of the quick start guide that came with it. Well, the full manual is only available in spanish and french. The only other manual in English was the quick start guide, which I already had. Well, there was a technician waiting to answer my questions, so I typed in my problem. Immediately, the (robot) technician asked for make, model, and OS of my computer. She then said to stand by to talk to a computer specialist. I am sent to a service website that is longer Insignia, and they want you to join their club for $5.00, then I think $29 or so per month and they will answer any technical question you would have in the future. They wanted your credit card information with the promise that you could cancel the contract at any time, which they were hoping you would forget to do down the line. Wait a minute, I bought their product, it didn't work, I wanted some assistance in case I was doing something wrong and they want to charge me for that for a product fresh out of the box purchased yesterday. So I didn't take the bait. I read a few more reviews, and some said they were having trouble/no luck loading the software in a Windows 7 OS. So to make sure the unit was working properly, I plugged it in to my laptop and it installed the SW immediately. It was working. However, as others have mentioned the fidelity is horrible into my beats earphones. I may return it tomorrow and try to find something else that I can hook to my pc to give it blue tooth. It made for a frustrating evening trying to get it to work, and the sound quality is only mediocre into beats earphones..
